Help With S4 Audio Set Up.

I was running the S4 with a Pyle Pro Hybrid amp through the CD/DVD input before someone spilled all over it! So I got a new set up but Im getting nothing to the Amp, amp powers on, S4 powers and is responsive with the labtop, but Zero sound from speakers and the LEDs on the amp don't move. This is what I'm running

S4 to Technical Pro LZ6200 with RCA's from S4 main out to input on amp
LZ6200 to 2 Gem Sound Tr100-1 through banana clips....i got a sub and some bigger speakers on the way but wanna start playing ASAP.

Here are the specs on the amp and speakers.
LZ6200
6200 watts peak power
1500 watts @ 2 ohms
900 watts @ 4 ohms
500 watts @ 8 ohms
Inputs: Balanced XLR, 1/4'', RCA
Outputs: Speakon, Banana binding post
Dual cooling speed fans
Iridescent blue LED meter
Clipping indicator per channel
Bridge / stereo selector
Built-in key lock (cuts audio output to prevent tampering)
Dimensions: 19''w x 3.5''h x 11.5''d
Weight: 21 lbs
Voltage: 110-220V Switchable

Again i got nothing here. Any help would be greatly appreciated. Thanks

Have you tried using the TRS outputs of the S4? Does the amp work with any other audio source?

And do the RCA outputs of the S4 work on other speakers?

Here is the speaker speaks
350 watts
10" woofer with high tempered voice coil
Piezo driven horn
bullet super tweeter
Carpet finish
Steel corners & Heavy duty handles
Inputs: Dual 1/4" and binding post
8 ohms
23 lbs
21" x 16" x 13"

The speakers work with a amp I tested at radio shack. They are passive and work when I plug them into the 1/4 inch inputs but they don't get loud of course. So I'm going to try the 1/4 inch main out to the main input on the amp and hope that works. It's like I'm getting no signal to the amp from the s4.
