PA 660 Auto Turn On?

[steakboy]

i have recently bought the PA 660 amp for my car. i have everything set up. i ran the power cable from battery to amp. ran the ground to the body of my car. ran a single RCA cable from my radio to the REAR amp RCA input. i ran the
spade thingy from my speakers (Pioneer TSA1671R, 220 watt speakers) to the rear input on my amp. i turned my car on and no sound came from them. with using no amp they work, but with amp they dont work. i look at the Power LED light and its not on. i look at the bad connection LED and its not on either. i am currently no using the bulk cable
thingy (the big rectangular one). so i am wondering if i NEED to use that bulk cable, NOT just the RCA cable, thanks in advance

You have to run a remote turn on lead to the amp. Your head unit should have one so just tap into that. If not you can just tap into a small fuse that powers up with the ignition like the radio fuse.

The auto turn on feature only works when you're using speaker level inputs.
