Ground noise with two amps


Recommended Posts

Ok currently i am running 1 aq2200(since my other one burned out) on 2 Fi btl's. I recently bought a amp for my vocals and noticed when i connect the rca's to the vocal amp their is huge ground noise coming from the subwoofer...and when i unplug the rca's from the vocal amp their is no ground noise from the subwoofer. Note the subwoofer is amped to the aq2200 incase u didnt figure that out :) They are both grounded to the seatbelt bolt if that makes a differnce. The rca's are also ran in differnt sides from the 0gauge battery

could it be the vocal amp? its a cheap one i bought just temp its a pyramid lol

yeah don't use seat belt bolt at all.. DO bolt it down /w a couple washers, a bolt and a nut (cost me like 1 dollar at home depot dude). make sure you don't drill into the gas tank. also, use some sand paper so the ground is free of any paint. be thorough.

make sure you have good quality connections /w your power and ground wires too.. you know in case a terminal fork is loose (if you use that). make sure the fuse holder is nice and tight

cheap amps do cause weird problems. see about trading it out with a friend's amp just to test it.

If I answered you in a well mannered, informative way, you asked a good question or had a good attitude. If I was an asshole, you asked a stupid question or you had a fucktard attitude... or I was in a bad mood.
