If you're running the amp in stereo (one channel to each sub) then your fears are justified. If you've bridged the amp, then not so much tp wprry about. A mono amp is always better.

Now about the gain controls. "3/4" is pretty darn high. What is the head unit? How did you arrive at that setting?

the HU is an Alpine cda 9827 with 4v pre outs, in an earlier thread "let there be more wats" rob stated that the output volatge was much closer to 1.5v. On the fosgate web site reccomended setting the gain at at around 3/4 for 1.5v, 1/2 for 2v, 1/4 for 2.5v and all the way down for 4v.

OK, that's a new one on me but then again I have not put a meter to an Alpine 9827 with the output at full volume. In any case, simply setting gains by reading instructions on the web and 'eyeballing" a setting on the pot is not the best way to do it, although it certainly beats not paying attention at all and just going for it! I don't want to repeat what was already posted in other threads, except to say that if you do not hear distortion or clipping, then it must be OK.

Is the amp bridged or is each sub on its own channel?
