Hifonics Colossus XX No Sound?

Bought this Amp used, Plugged everything in. Powers On No Errors, but no audio.

Sub(RE XXX) is wired Right, Tested with another Amp and it plays
Rca cables Are New, so no probs there

When using the Remote Bas **** that it came with I can hear a Little static and a hum getting louder threw the sub when turning the **** up.

The Deck is a JVC Exad AVX2 It only has a single Rca out for subwoofer, Not Left and Right. Does the Amp need a Signal From Both Left and Right? Could that Be The Prob?

Any Suggestions?? TIA

Maybe you could take a look at the internals and see if anything appears burnt or busted on the inside... Are all the dials set up right on the amp (gain, LPF and the likes)?

Got it working with my old shittier JVC Deck that has both left and Right Rca's for Subwoofer out...So My Guess is It Needs Both left and right in to work.
Now could I Buy some sort Of y adapter to split my 1 Rca Out of my Deck to 2 Rcas to the Amp??? Any probs with that?

Yes you could and no there would not be any problems.

is it possible that the 1 pair of rca's you found are input not output?
i highly doubt splitting signal in 3 will do much for you
only other thing that comes to mind is that certain decks have an option to turn off output signal
maybe its some kind of a setting on the deck you need to enable?
good luck!

look what i found:
JVC KD-AVX2 EXAD - eBay (item 120220026456 end time Feb-14-08 14:44:43 PST)

look at all thouse rca's, maybe you are missing them and they plug in the back somewhere?

Nope they are all Labeled Clearly. Mine was hooked to the Subwoofer out, I can see it in the Pic, after I Reset the Deck, the amp is now Also working with it to off the mono RCA.
Must have been some setting.... but it wierd I never Changed Anything When I took my JL 1000\1 out and it worked. But Anyways I got it working. Thanks for all your replies guys..
