    speaker noise problem!!

    I have had a sub and mono amp hooked up for a while and doing fine. This weekend i hooked up a 4 channel amp to the stock speakers since it was laying around and now im getting a low bass like crackle noise with car on then when i start engine the noise gets higher pitched, more of a buzz and changes with engine rev.
    -I never had this problem with sub so i cant imagine its the head unit or its ground..
    -My rcas are on the opposite side of power wire, they cross once at a 90 degree angle and its through the carpet..
    -My amp ground is same bolt as sub amp and its a good one...
    anything else to check? would swapping rcas with my sub amp help to eliminate bad rcas?
    could it be just a shltty amp?



    ref: bought from TurdFergueson2, scottiej, mgbcs, Groundpound4200, fasfocus00, loudcartunez,

    It could be anything the RCA cables it could be the way the box is built or it could even be the coils going bad

    Check the ground wire? Also do you have a pioneer HU? Try grounding the RCA's on the HU by wrapping wires around the RCA's. I had the same problem with the alternator wine and this fixed my problem. Only try that on pioneer HU though.. Not sure on other brands of hu

    Re: speaker noise problem!!

    I read the pioneer thing but i have a kenwood.. and my ground is the same bolt as i used for my other amp... so Im starting to think its just a crappy amp... Could rcas running next to other wires for my car make a difference, like power wires for tail lights or trailer lights?
