Ok, I know Im a noob on this site but here is my problem. First off my system consist of:
Alpine Iva-D310 headunit
Alpine 6.5 components
Alpine 6x9"s
Alpine MRA-F350 theater amp
Tsunami 1.5 capacitor
Ok, my F350 is currently installed and it sounds great with the headunit. My problem is I upgraded to the MRA-D550 Digital Theater Amp and I get sounds like engine noise but its there when the engine is off also. I sent it back to Apline and they replaced it under warranty. I get the D550 back (brand new) and the noise is still there. I checked my grounds and they are all fine.
My question is, is there a particular way the D550 needs to be installed? Like I Said, if I put the F350 back in it plays fine. I cant seem to figure out where the noise is coming from I also tried changing out the Ai-Net cable with a brand new one and still the noise is there.
Can anyone here help me out before I put a brand new amp on ebay, I am tired of messing with it.
