i am getting alot of engine noice from my front 2 speakers, i am running two amps, i rewired them and i cant find anything wrong, however i have bad engine noice, i cant listen to my system. It started as soon as i hooked up my second amp. They sound awsome when the cars off, but as soon as it is on, the engine noice in unbearable. thanks for any suggestions

 

i'm pretty sure u have a bad ground wire or have grounded the amp in a bad place. try to ground the amp in a new location and make sure u file down and clean the ground location before installing. this should solve ur prob
