Adding a 4 channel amp is a great idea. Very nice! It means 2 channels are sharing the workload of one speaker between them and therefore and drive it with more power. A 4 channel car amp is basically an expanded version of a 2-channel amp. This saves installation space and makes it easier too.
You may want to buy and install a separate amplifier wiring kit to simplify the process of wiring your subwoofers. If not, you may need to connect the woofer directly to the battery and the car's stereo and ground the woofer manually.
Install and test any tweeters. As with woofers, tweeters, which produce high-pitch frequencies, can be easy or difficult to install based on the factory components of your car. If your car came with tweeters, you may only need to install the new ones in the existing housing and connect them to the existing wiring harness.

If, however, there are no spaces to install the tweeters, you may need to make your own or expand existing ones, use a mounting bracket, etc. Luckily, tweeters are much smaller than woofers, so the adjustments you'll need to make will be minor in comparison. As with woofers, if your car didn't already have any tweeters, you may need connect the tweeter directly to the battery and stereo and ground the tweeter to the car's body. Replace all panels and speaker grilles.
When all the components of your new speaker system have been installed, tested, and securely mounted in the car, you may replace any speaker grills or panels that you had to remove to install the speakers.
Make sure you've kept any screws that you had to remove to take the grill or panel off so that you're able to re-secure them properly. Congratulations - your new speaker system is ready to use! Maybe the ground is not properly setup, thus making noise in the form of static sounds.

Include your email address to get a message when this question is answered. If you find yourself in the situation above, you can do a couple of things. Replacing your radio with an aftermarket one would give those aftermarket speakers more power.
Also, if you want to keep your factory radio's appearance, or perhaps, a feature like steering-wheel mounted controls, you can amplify your factory stereo. Helpful 0 Not Helpful 0.
If you still have your factory OEM radio installed, installing aftermarket speakers may not improve sound quality for you. You may find that your radio lacks the deep bass like it used to have with the original speakers. This is because factory original speakers are generally constructed with paper cones, which require less power to deliver bass.

In the case scenario that I just a 5 channel amp how am I supposed to connect the single subwoofer speaker to the amp out, and also how do I connect the amp input since there are two subwoofer output from the headunit? For some people a 5 channel amp is plenty, especially the new models like Pioneer GM series with so much power.
However, a 5 channel amp saves spaces and makes installing easier to. It depends on what your needs are. Yes, if you change the head unit, using the RCA connections would deliver the best sound. It will accept a wide range of input levels and should work with RCA line-level inputs. There should be some items you can find that will do the trick. Thanks for the info. Also, that would be good if you can show me some items for RCA to bare wire.
Mar 26, Most all stereo receivers, amplifiers, and standard speakers (i.e., ones that are able to receive signals through speaker wire connections) feature terminals on the back for connecting speaker wires. These terminals are either the spring clip or binding post type. Hook your audio source to amplifier, play test tone and turn the volume up. Your audio source might clip so firstly checking outputs with DD-1 or oscilloscope should reveal any distortion or clipping, if everything is ok you can raise your gain until waveform starts looking . Nov 11, Amp Wiring: Head Unit and Speakers The way that you wire your head unit to your amp will depend on the outputs on your head unit. If your head unit has multiple preamp outputs, then you can connect each set of outputs directly to one of your amps. If your head unit doesn't have multiple preamp outputs, then you'll have to check your amps.
These will make your installation much easier and are reasonably priced, too: RCA female to speaker wire adapters. Hi, i have pair of focal vrs 60rms running through hertz he-4 75watts rms x 4 at 4 ohm and the speakers sounds bad no bass.
I have connected them on channel A and have sub on channel b bridged. Any idea why they dont sound good. What possible i have done wrong? Btw i run 16g wire from amp to front hu wiring harness then using factory wiring.
Audi a3 8p. Hi Pawel. Are you using the high-pass crossover function on the front speakers? If so, switch it off and see the result. How did the factory speakers sound? Was there good bass for those? Unfortunately, not all speakers will sound good in all car doors. This is a temporary situation - I bought the amp with the intention of running new speaker wire and RCA cables for signal and connecting all the speakers. Easy enough, right?
I had planned on just hooking up the two front door speakers to the tweeters in parallel two channels and then hooking up the rear door speakers to the other two channels. Am I overthinking this or is this a problem? Not sure if that would even work, or if it would introduce problems with delay or something else.
Hi MJ and thanks for dropping by! As you might expect, both have pros and cons. And to answer your question, yes using speakers in parallel does drop the total speaker load the amp will see. You can use both the tweeters and the GTO speakers on the front channels by adding inline series power resistors, 1 per speaker. Therefore if we do this for both the tweeter and GTO speaker on each channel, when wired in parallel the amp will get a safe 2 ohms load.
You can see an example of the wiring set up in section 3 in my wiring diagram here: Wiring diagram for adding inline resistors for adding more speakers safely. The trade off here is that while it lets you use 4 speakers on the front 2 amp channels, the resistors will consume a good portion of the available power. Ideal solution You could get a 2nd amplifier just for the additional 2 GTO speakers. There are many good budget 2 channel amps that would be great for this. Head units are very limited in power they can provide W usually.
You could use a very compact class D 2 or 4-channel amp for the rear speakers for example. Thanks, big help! Again, very happy to take any links if you have recommendations. Also, I found that with my car Impreza I can run cables through the rubber door boots without disconnecting anything but trim, by using a heavy duty 3 foot long zip tie with the tip bent up slightly like a ski and the other end snipped off, and a little windex for lube.
Hi MJ. Sorry for the delay as I was having Wi-Fi problems last night. It happens. This also lets you find many places closer which is important if the ground wire is short. Often times many in wiring kits are ft long etc. In all cases I would use a good quality crimp ring terminal on the ground wire. Amp wiring kits include these and make installation a lot easier. You can buy this by the foot or on rolls reasonably priced.

Hi Donzel. Really it should be very straightforward in most cases. Just be sure to plan for getting enough speaker wire. Besides trail and error is there anyway to know which output is driven by which input? Hi Mike. You have a very nice write up, very easy to understand. I was wondering if you could help me out with my situation. I have a Tahoe Z71 with Bose and Onstar. Everything has been fine. However, I still wanted to add more power to the door speakers.
So, I ran new speaker wire through all the doors directly from the speakers to the 4 channel amp. I add power and ground distribution blocks. After everything was finished and cut on the subs are working fine and the only speakers working are the tweeters in the A and D pillars, which I did not touch.
Any suggestions or places to point me in the right direction? The first thing I would do is to make sure the 4 channel amp is working right. I would disconnect the door speaker wiring from the amp and use a test speaker right at it to check it. I have an aftermarket Enon GF with Qpower watt front speakers and Qpower watt rear speakers cheap I know but they sound bad and have a crunch Thank You.
You can definitely run wire to each speaker from the amp and in some cases you have to bad factory wiring, bypassing a factory amp, etc. Great article. Very helpful.
Can you assist in a suggestion for the following marine installation all 4 ohm. Installed speakers are.
One Subwoofer 10 In. I also have the original 2 channel amp. Should I ditch the old amp or can I use it to drive the sub-woofer? Let me know your thoughts. Thanks Rex.
Charming question how do you hook up a amp to car speakers amusing
Hi Rex how are you? Note: I edited your comment to keep it small. I would just use that amp for all of them.
Running the amp's output wires to the wires on the adapter harness is how you avoid having to run new speaker wiring throughout the car. That's the bottom side of the triangle in the photo - speaker wires from the amp connect to the speaker wires on the adapter harness. Then that harness plugs into your car. To hook up speakers, you just connect the speaker wires to the appropriate outlets on the A/V receiver. Before you plug and play, though, there are a few points to remember. Keep your speakers in phase. Each speaker wire consists of two conductors, a positive and a negative. Mar 27, Connect the front, rear, and subwoofer speaker wires from the amplifier to the corresponding speakers. 5. Run the power lead from the amp (ensuring that it's on the opposite side of the car .
However, it gets a little bit more complicated since all channels use the same crossover, it appears from the manual. I have a question. The amp has both high level and low level inputs. The headunit only has 2 channels and no rca outputs.
On the amplifier my high level inputs only have 3 connections for each channel. They are labeled L, com, and R. Not sure why mine is different. Any suggestions on how to use this setup.
May 02, There are 3 basic ways to get a signal to your 4 channel amplifier: Connect speaker outputs to your amp's speaker level inputs Connect a line-level adapter to the radio then use RCA cables to the amp Connect your radio to the amp using RCA cables directlyTotal Time: 5 hrs 45 mins.
My other question is would I be able to use a Line level convertor and use rca Y adapters off of it to send signal to all 4 channels. Yes, definitely you can use a 2-channel line level adapter and then just go from the RCA jacks to the amp with inexpensive Y adapters if you like.
You could run a pair of RCA cables to the amp and then connect the Y adapters there if you want as opposed to running a 4 channel RCA cable to the amp.
This seems to be in my budget and I am keen on getting this amplifier instead of Pioneer GM-D - which you have reviewed and recommended. Please let me know about Pioneer GM-D Thank you. Hi Sam.
How will I get a signal to the sub woofer? Thanks for the brief explanation. I have managrd to connect up everything in order. How do I hook them up on the amp. Hi Stephen. Is that right? Otherwise you may need a ground loop isolator for RCAs. You can damage your head unit or amp. Hi Marty, thanks for taking the time to help us all. Happy new year btw. You kind of have to choose based on your setup and the speaker outputs.
If you need separate level control separate gain control for the 6x9s then use them alone on the front or rear channels. Hi Marty am from Mauritius and have a question concerning wiring. I have a Pioneer GM D amplifier. Or can you suggest how I should do the wiring please?
Hope to hear from you soon. Hi Ben. The GM-D has far more power available in 4 channel mode than the 6x9s 80W each can handle anyway. When running speaker wire from the amp to the wiring harness behind the radio.
How do you hook up a amp to car speakers
Do i run the speaker wire from the amp to the harness that came with my aftermarket HU, or do i run the speaker wire from the amp to the factory wiring in my case the Metra harness kit? I hope you can help me out with this or have the time to.
This avoids having to cut the factory wiring. A short can permanently damage the output stages of the head unit. Do I gain anything by connecting two pairs, say the front, to the head unit and the rear speakers to the amp? Hi, David! That assumes, however, the speakers are good enough to hear the difference. So even a decent quality amp can greatly outperform them. I would say it depends on your goals, but speaking from experience, using a good amp to drive decent quality speakers is worth the effort.
Hey marty, Just a quick question I have a 4 channel amp and am planning on running the front and rear speakers through it. Can i run just the 2 RCA cables from head unit to amp and then wire the speakers to the amp or do I need to do both as in Run RCA cables from head unit to the amp and run speaker wire from head unit to amp then run the speaker wire from the amp to the speakers themself I Already have a set of RCA running to a single channel amp thats running the sup but my head unit has the other 2 ports for front and rear, Just not sure if i have to run both or just the RCA cables.
Idea has how do you hook up a amp to car speakers join. agree with
If you could let me know that would be muchly appreciated as im a bit stuck cheers. HI Richard. If you connect speaker inputs and RCA inputs too it can damage the head unit. So you would 1 run RCAs from the head unit to the amp and 2 run speaker wire from the amp to the speakers or factory speaker wiring in the dash, depending on your installation.
Marty was extremely helpful right from the start.
To my delight I received a reply the very next day. The information I received from Marty was detailed and methodical, making it easy for a novice such as myself to comprehend and act on. Furthermore, I sent a second email requesting more details about the setup i wished to pursue, and Marty once again willingly responded to a number of my questions. Not only can I now start work on my car audio system, but my understanding on the subject has tremendously improved, thanks to Marty.
Great guy. I am hoping you can assist me. I am struggling with the following issue for days on end, and my car audio install is still not working right. I have all of the wires run and have checked to make sure they are all wired correctly that I know of.
All of my speakers work if I move a working rca to each individual input on my amp though even if i use the left rca cabl. All of my gain adjustments are turned halfway on the LOC and amp.
If i change the sound to the left side of my car on my head unit i can hear very faint almost no sound coming from the speakers.
The best way to wire multiple amps to a single power cable is to use a power distribution block. That allows you to use a single cable for most of the run, including the crucial portion that passes through the firewall and then to use shorter individual cables to actually connect to each amplifier.
Rather than grounding your amps individually, a distribution block should also be used to provide the ground connection. In a mirror image of the power distribution block, the individual amps should be connected to the ground distribution block, which in turn should be connected to a good chassis ground. You can use the same ground block for your other audio components, which is also a good way to avoid ground loop issues. In some cases, you may find that a single remote turn-on lead is unable to handle the current draw demanded by multiple amps.
One way to work around this issue is to connect the turn-on leads from your amps to a relay, which is triggered by your head unit. Rather than receiving power from the head unit, the relay should be hooked up to another source of battery voltage - either from the fuse box or directly from the battery.
That will effectively isolate the turn-on signal from the head unit from the multiple amps, which will hopefully allow you to avoid any issues with current overload.
