i tired so many places but it never seem to work. no matter where i had ground it, there is still the exhaust noise present. so far, i had tired 3 different amps and 2 set of rca wires with no luck. ground in the shock tower, under the seats, behind the rear rears, near the trunk and etc still doesnt seem to get it right. any help would be great. thanks

 

what do you mean by exhaust noise?

do you have your RCA cables and your power wire ran on the same side of your car? That can sometime account for unwanted noise

 

the you can hear the sub whistles when the car is on. my rca runs through the middle and power runs through the passenger side of the car.

 

whats your sound system consitest off.

 

did you shave the paint off when you grounded it? What specific type of amp are you running? Size of power wire, ground? Maybe try getting a grounding kit if all else fails..

 

Are you using cheap RCA's or nicer shielded RCA's?

 

4 gauge power and ground. using fosgate rcas. the whole kit was a fosgate from bestbuy. i sanded the bolting spot for the lower rear seat of the integra to bare shinny metal.

 

Do not use any existing bolts on the car. Scrape it down to the bare metal and use a metal tapping screw. You want this as close to the amp as possible. Next, run and 18 gauge wire from the headunit's ground to that same spot where you're grounding the amp. You should also run your power wires 8 inches away from your RCAs, in other words, on opposite sides of the car. If you have to cross the RCAs and power wire, cross them at 90 degrees. And finally, if you still have noise, you might want to replace your spark plug wires. I recommend Magnecor. If you still have noise after that, your amp and/or RCAs are ****.

 

My guess would be you have a bad stereo ground.

What type of amp do you have? Kicker?

Run the RCA's across the carpet for now.

What deck do you have? Make sure it has a good ground.

Make sure the ground of the RCA does not touch the ground of the car. They are not the same ground.

If all else failes pull the deck out. Connect the deck to the same spot the amp is. If you still get noise you may have defective equipment.

As long as the ground lead is making contact with the cars floor pan, it's as good as it's going to get.

What is the make and model of the HU, model of the MTX amp where and how is the amp mounted?

And as has been asked, exhaust noise", there is "system noise", [background hiss] and ign. noise, [best described as a ticking, buzzing noise sound of each spark plug as it fires] and most common alt. whine, [a whining siren kind of sound that changes pitch as you rev the motor a little, and gets louder as you load down the alt., turn things on in the car, ign. noise and alt whine will not be present when motor is not running.
Which on do you have? 94

it isnt a new car haha. the car is back in the shop to be repainted since there was a little paint chip from a recent fresh coat of paint. the HU i am using is the pioneer 4700 and i am not sure about the model of the MTX amp since i just got it 2 days ago and i threw the car back into the shop yesterday. right now, the amp is just laying on the trunk cardboard floor since i havent decided where to mount the amp at. most likely the amp will be mounted onto the top piece of the seats. i think the noise like you described is more of the alt. whining sound since i can hear the sound ampflied as i rev the car, but the funny thing is even if the car is off and the car is on the ON position, there is still a slight hint of noise coming from the sub.

Touch the ground of the RCA near the amplifier with your finger with the motor off does the noise get louder?

 

Ahhhh Pioneer I have more noise problems with Pioneer HUs when connected to another brand of amp then with any other brand of HU
Sometimes I have had to change to Pioneer amps or change to another brand of HU, not always but sometimes. Do you have access to another HU that you can temporarily plug into your system? 94

 

when i had this same exact problem in my '95 legend, it was the RCA ports on the amp that was the problem (where you plug your RCAs into the amp).

EVERYONE told me that i had a bad ground. so i changed my ground to all the holes that i could hook it up to..but it never went away.

so...one day i got so annoyed of the problem that i decided to sell my car (it also had other problems that i was annoyed about). upon cleaning up my trunk area, i found out that the RCA ports on the amp were LOOSE!...as if they came off before and someone put it in wrong so they didnt sit in there tight enough. so i made sure that they were in there snug and that nothing else was loose...and WALA! problem solved.......but i still couldnt put up with the other problems so i sold the car anyways..ahah

Hope this helps. maybe you have the same problem? check all the ports make sure nothing is loose!! good luck, let me know how it goes.

 

dude the amp's ground cable has to have direct contact with metal.
take a screwdriver and scrape around a bolt in the top of your truck,
then use it to be a ground by bolting the ground cable to the bolt.

most trunks metal shells are painted a color or with a finish that you must scrape off first, then all should flow smoothly. good luck
