ok guys when i hooked up my amp and speakers they sounded like shit so i started messing with it and it started sounding better it sounds kinda ok now. but whenever i turn the car on it can here bass as if the stereo was on and i havent even put the face plate on yet? i thought maybe it was the rca cables, anybody ever run into this before if you have help please.

Its called interference or feedback. Check your grounds. Does the noise increase with the RPM's of the engine?

mr.crx

no not that i can tell but it happens right when i turn the car on. so maybe i started to here like a little whisle that i have never heard anymore and it climbs as the rpms go up but i do have an intake but have never heard that before.

Do your grounds share a path with anything else? It does or does not increase with RPM increase?

mr.crx

i am not sure its got this little whistle and it sounds like its coming from back there. no my ground wire doesnt share a path its on its own.

Check your ground wires. If the sound get higher as your RPM gets higher, that is most likely it.

Turn on your stereo, turn down the volume, turn on your car, rev the engine slowly.

You grounds should be solid and be contacting SOLID BARE METAL (as in no paint). Where is your amp's grounding point?

mr.crx

to the frame underneath the carpet in the back its a crx by the way

Is it bare metal?

I would check all the connections in the wiring. What kinda amp is it? Also, are they decent RCA cables?

mr.crx

well my friend gace me the rca cables and they are brand new but i think they came from a walmart wiring kit not sure though. not sure what kind the amp is got that from a friend. i am more i will get under the car and work on it all day but dont know shit about the wiring inside of it. could it be the rca wires?

mr.crx

i believe the amp is 4 channels at 1600 watts. what gage ground wire should i have on there i belive the one i am using is an 8 gauge
