[QUOTE="Brian jojade, post: 81949, member: 211"] Re: JBL SRX / QSC PL236 underpowered? Like all things audio, there is not one right answer. If you get amps that let you drive very close to the edge, it makes it easier to go over the edge and blow them up. Having amps rated slightly smaller will give you an advantage of a functioning 'warning' light that comes on, which for some reason is labeled 'clip'. With your amps, running in stereo mode to the speaker, you'd have to try really hard to get the speakers to blow up. If you bridge the amps, you're going to be just about at the rated program power that you want to have to get maximum output of the speaker. However, this gives you more opportunity for an 'oh shit' moment where you aren't paying attention and you blow stuff up. If you can get there without bridging, that's even better. As far as the speakers that you have, the 715's are decent speakers. I've got a dozen or so of them. However, they do lack in the ability for vocal clarity at distance. Your rig I'd use in a venue where the throw distance needed is 50' or less. I'd run the tops in stereo on one amp, and bridge the subs. You can tweak the crossover point to balance the power usage. I'd guess about 95hz would work fairly well, taking the low end load off the tops. If you get more subs, get more amps for them. I wouldn't run 4 subs off that one amp. [/QUOTE]
