I have a Sony 5.1 receiver (STR-DE985) that I need to hook up to subwoofer(s) via a power amp.
The receiver has a subwoofer pre-out w/ the requisite low pass filter. It's currently connected to a Carver WCA-400 power amp (400W @ 8 ohm bridged) which is in turn connected to a 12" sub. That has worked just fine.
Purchased another power amp (Gemini XGA-4000, 700W @ 8ohm bridged) and there's simply not enough gain on this amp to get any usable output. The old amp does fine; this amp, the gain control simply runs out of room before I get any sort of decent volume.
I'm hooking the same signal and sub from old amp vs new. Old one kicks it pretty good, new one, hardly anything.
Is there a pre-amp sort of device I can use to boost the signal to the new amp? Please recommend one if so. I need to get both these amps running together at a parallel level of volume (or as close as I can get) so that I can add another sub.
