Subwoofer/Amp Noises

[CanNotT0uchThis]

Ok well here we go I have installed a rockford fosgate T2 with a Lanzar MXA 282 2 Channel Amp and I am having problems with a ground loop at low volumes I hear a low buzzing/humming noise and When I accelerate it sounds like I have a turbo.. I already know about a ground loop isolator but people say that it is just putting a band aid over the problem how would I go on and fix it completely?

Also, have you checked to make sure RCA's arent crossing your power wiere anywhere?

Sounds like the rca cables...but lanzar amps...mm, how to say this in a nice way..you get what you pay for.

Is your RCA near any power source or wire?

Nope they are on opposite sides of my car put if I unplug RCA's it stops. Also this sounds weird but when I put my car in reverse it stops. I even unplugged speaker wire but I still heard it. And another thing if my car is just running off the battery I dont hear it either

I would say check your ground on the amp. Make sure you have bare metal where it is grounded. Also what head unit do you have?

[Guest]

wait so you unplug the speaker wire and you hear it through where, the amp itself?

[SnowDrifter]

Did you try grounding your RCAs?

I have a JVC Head unit. What I mean is I unhooked speaker wire from subwoofer and I hear it through my speakers but when I turn volume all the way down on stereo I don't hear it also I'll have to look into grounding RCA's cause I have no idea how you do that but I'll give it a try. Oh and my amp is grounded to bare metal sanded and scraped Paint off and the ground is not lose either.

Get a better set of RCA cables, try ground your amp in a different spot (sand to bare metal, drill through the metal, and secure it with a nut and bolt with washers) or try getting a better set of spark plug wires, or try doing the big 3. Those are the usual culprits and fixes.

I almost guarantee it is not the ground because I've had 3 different ones the one.. But yeah I'm starting to think it might be my RCA's because I've tryed almost everything else even running them over the seats what kinda of RCA's would you recommend? And thanks for suggestions and if you can think about anything else please post. Oh and about the big 3 me and my dad just put a new alternator in back in November and my battery is not even a year old yet but could that be it? Im not super smart about car audio either but would I really need a bigger alternator and battery for 1 12?
