2004 Honda accord amplifier with stock radio
 

It looks like replacing the stock radio would be quite hard because of a stupid idea to put the controls on the radio itself too.

Anyways I am not ready to do that anyways.

I have a set of mtx 4500's I want to hook up and I need something to hook up my RCA ends on the amplifier to.

I had to replace my civics radio because of this and well it is not a easy option anyways.

So I read on here and saw this suggested:

I really do not want to spend 60 bucks(the cost of a cheap radio) to just get a adapter.

Are there any cheaper adapters?

that PAC HON adapter can be bought for around $40 at sonic electronix .com. I just got mine in the mail and installed it today, what a coincidence!

This one right? That saves me 10 bucks which is better than nothing.

Why does it have 4 rca outputs when my AMP only needs 2?

it has front and rear RCA outputs. if you only use the front outputs, that's fine.

Since this thread's been dead awhile I'll go ahead and revive it a bit with a couple of questions that need answering.

1. I put in an amplifier in using the PAC adapter, but like many others have gotten a VERY audible white noise when the headunit is powered on. It distracts from the music and gets annoying fast, so my question is, what are my options in eliminating or reducing this noise????

2. I just installed a subwoofer and when i turn the radio off from the headunit with the car running the sub makes a very loud, low noise. Just like a single frequency it plays for some reason. When the unit is on, the sound goes away. (the white noise takes its place lol.)

Any help and suggestions are welcomed.

THANKS

does the background hiss stay constant with volume, or increase with volume?

what are the gains set at (amp and PAC adapter)? can you lower the gains on the PAC adapter and just use more head unit volume?

what amplifier make/model is giving you noise? the remote turn-on given by the PAC adapter should shut off the amp when the HU is off.

where did you get your remote turn-on from?

in your case, it sounds like the amp is on when the HU is off. a switch on the remote wire can fix that. amp on last, amp off first.

Thanks for the reply keep_hope_alive,

Its a lil hard to tell, but the hiss is fairly constant, its loud to begin with so you can still hear it on medium volume levels but it goes away when I'm blastin the radio :).

gains on the amp are set to about 1/2 for my sub and fronts (the amped components) I didn't even know the PAC adapter had gain settings, how do i change them?

My amp is the Power Acoustiks STAX 1600 4 channel version.

The owner before me must have installed an amp in this car because there were already power, ground and turn on wires leading to the back of my trunk. I found that the turn on wire is connected to the interior fuse box, connected to the headunit fuse. Is this incorrect?

I have the same problem. When I turn off my headunit I get this very loud hum, almost full volume, it scares my passengers. When I start car I get the same thing. I purchased a PAC TR-7 but I think the issue is from the stereo and I can not for the life of me find a turn on from the stereo itself. The car has the factory Nav. I disconnect my hi/lo converter and of course I get no noise so I know its from the headunit, but why I do not hear it out of the speakers is beyond me. HELP!!!!!

I changed my remote turn on from the fuse box, to the provided pac adapter's turn on cable. It somewhat solved the problem. It will make that noise for about 2 seconds now when i turn the radio off, but the fact that it turns off at all is good.

I'm still getting some pretty loud hissing from my speakers. And i looked at the pac gains settings and don't know what to make of them. how do you change them? seems even the smallest screw driver doesn't fit in those holes. What are they set at stock?

you must adjust those gain settings. you'll need a precision screw driver kit - cheap ones are $5. it's anyone's guess what they are at now.

Well sorry for your time on this thread but I've already got my JL clean sweep in and am going to be replacing the PAC adapter with the clean sweep. I got it for cheap on ebay and it also adds an aux input, those which cost around $150 for a USA spec adapter for ipods in accords. Now i started a new thread which will hopefully get some questions i have answered about the clean sweep.

Hey JCNY, I'll let you know how the clean sweep sounds so maybe you'd get one too. if it fixes all these problems we're having...

Good lookin out!

I got the clean sweep workin and i'm happy to say the white noise is far reduced and can probably be completely rid of if I were to improve my grounding. As far as sound quality, it's great. Everything's pretty much crystal clear. The iPod aux in works well too and sounds awesome as well. The install was a little tricky but I'm a teenager and got it workin basically by myself. The whole system turns off with the car without a problem. I got the clean sweep for cheap on ebay and i believe it's worth it for what it did for me.

Now that I've got all after-market speakers and a sub all amped up with the cleansweep processing it all, i don't know where to go to next! I could probably go for a round of sound deadener, but am a bit skeptic on the price to improvement ratio. Plus finding the right brand and type of deadener seems tough. Maybe some input from other accord audio enthusiasts?

deadener is crucial for good performance. the environment the speakers are in largely determines their performance.

Second Skin makes the best products.

Rammaudio makes good budget products.

I was able to kill the turn-off thump from the subwoofers by adding a small wire to one of the RCA jacks and grounding it. My remote wire for amp turn on is running to an empty slot in the fuse panel (position 31 I believe) which gets power only when the switch is in the on position. To fuse the circuit, I put a ten amp fuse in that location with the remote wire wrapped around 1 of the prongs (use the side that doesn't get power with the key in the on position. Works perfect. One side effect though to my sub/amp install... cutting off the head unit using the power button causes feedback in the sub (endless bass tone). Btw, I fed the audio from factory radio using the rear speakers' wires to the MTX electronic crossover. Then, I used the RCA outputs from the crossover to feed the sub amp.

on the sound deadning, damplifier pro is some pretty good stuff too.

the constant noise from the sub with the head unit turned off maybe coming from the anc system if you do not have them disconnected.
