Subs getting no sound

[CombatNiinja]

Vehicle:

2000 S10 Xtreme

System:

HU: Pioneer DEH-2200UB

Subs: 2 Fusion Cs-SW120

Amp: POWER ACOUSTIK GT1-2400D

(Paid $100, so not bad til I can afford better)

Wiring Diagram:

Problem:

First I hooked up the amp to be sure it got power. Did that, then moved onto subs. I prewired them in the box, lugged the box and put it in the very limited space i built it for (lol) .. Turn on the truck and no sound from the subs. This amp is supposed to have a bass knob, so I hooked up an old Planet Audio one to it and when I play around with that the subs make kind of a feedback noise, same thing happens when I mess with the inputs.

Any ideas?

I hope its not the inputs because last time I had a system I thought that might be it and put all brand new wiring in. That ended up not being what was wrong so I just bought this stuff off a friend.

I definitely hope its not the headunit. I have to tear apart my entire dash just to take it out.

Anyways, any help is greatly appreciated!

Thanks guys!

Are your RCA's good?

Are the subs new or used? If you tried another amp and no sound came out of the sub, more than likely the voice coils may be fried.
