Trying to hook up 2 subwoofers to home AV receiver.. no sound from subwoofer pre-amp outputs.. please help

post #1 of 2
Thread Starter 

Hi,  I have a Ross Mega Amp 800 2ch (I assume it puts out about 400 watts per channel?) and two 8 ohm Sonic loudspeakers with titanium horn tweeter and 15 inch woofers.

 

The AV receiver is a Marantz SR6008U .. about 115 watts per channel..

 

Problem is I want to just use the woofers as subs,  so I took the 2 rca subwoofer pre-amp outputs (signal only I assume) from the Marantz and went to the 1/4" inputs on the Ross amp. 

 

No matter what there is no sound from the woofers!  I made sure in the Marantz settings its' set to LFE+MAIN - which in the manual it says you should use that so there is sound all the time, not just when there is LFE. 

 

The 2 knobs on the front of the Ross amp that say "Peak",  there is 2 lights above them and they don't light up.

 

I know the speakers work, because if go from just a regular left or right channel from the Marantz to the speaker the whole speaker has sound.  There is a knob on the back of the speaker that controls the tweeter and I want that turned all the way down so somehow I can just be having subwoofer signal from Marantz and using the 15" subs...

 

There seems to be no sound when going from the subwoofer pre-amp outputs to the amp and amp hooked up to the speakers, 

 

Is the amp shot ?  The amp is older and I bought it used..  the Marantz is basically brand new.

 

Also is that amp too much for these speakers ? (I think the speakers are rated at 185 watts rms max)

 

Why can I not get any sound?

 

Thanks in advance for any help

My guess is that the RCA to 1/4inch adapter is the wrong adapter.
