horrible idle / engine shake after car audio install - Toyota Yaris Forums

Split · 04-28-2011, 12:17 PM

So last night I was looking for something to do and i found some old audio equipment, which I decided to install in my wife's yaris.

1) 4channel ampline amp mrv-something -- powering the factory speakers (extremely low gain)
1) 2channel low-end rock fosgate amp bridged powering 1 10" rockford fosgate subwoofer

When I hooked this all up, the car starts to shake terribly when in drive and holding the brake. if i open the hood, the engine is violently shaking back and forth. It doesnt seem to happen in park or neutral, only in Drive when the brakes or ebrake are engaged.

Any suggestions?
