As far gaining the "extra power" as described in 'fighting for power', you need to do nothing. When you run an amp in bridged mode, you are already optimized as described in the article. The article deals with situations where the amp is run in stereo mode.
It sounds like you are running your system in the most powerful configuration given the equipment you have.
Just to check, in the setup you describe, you should not be using the black speaker terminals on the amps at all and the speakers should be hooked up accross the 2 red terminals. If that is how you have it wired, then you should be all good.
: Hi, my name is Sergio, how are you guys? I read your article on "fighting for power", and I have a couple of questions that I hope you could answer for me.
: I'm running the low signal from my crossover to two qsc plx3402's(I'm using a 1ft xlr cable from input B of amp #1 to input A of amp #2 to make both amps run the same signal[lows]) For subs, I'm using four cabinets of the jbl sr-4719x(two 18" speakers per cabinet, which are rated at 1200 rms at 4ohms). I'm running two cabinets per amp, bridged. The way I have it hooked up is from amp to cabinet 1, then, from cabinet 1 to cabinet 2, I do a "daisy chain".
: Now that you have an idea of how I have my system hooked up(I hope is the right way!), my question is this...Since I'm running my amp bridged, do I need to switch the positive end of my cable going to the speaker to the negative of the speaker, and then the negative of my cable to the positive of the speaker? Or do I only need to switch the ends on my amp? Or switch the ends of my amp and the ends of my speaker?
: I'd really appreciate your help. Thank you.
