car stereo problems

[hollxiter16]

ok so today i hooked up everything new in the car. new pioneer radio, gutted the factory amp with a new sony explod and 2 12"kickers with 1000watt amp.
well everything worked fine until i hooked up the amp for the speakers. now my speakers squeal when the engine revs up and the sound cuts out and the light on the amp turns red. now i have a pre out going to the sub amp then i have preouts from the sub amp going to the speaker amp. any help would be great.thanks

The preouts on the sub amp is to link two amps together for more power if running several subs. Your mids/high amp needs to have its own independent rcas to the back of the Pioneer.

i think i figured it out. i unplugged the rca from the sub amp so all i could hear was bass and then i tapped the ampo a little bit and my subs started spazzing out so i think its the amp because all connections are good.
