can't increase sensitivity on JL amp
I have 2 12" JL audio W3s in a sealed box powered by a JL audio 500/1 mono amplifier. I also have a Rockford Fosgate punch capacitor hooked up along with a hi lo converter because I'm still using the stock head unit. Whenever I try to increase the sensitivity of the amplifier, the subwoofers would start rattling when I turn off the headunit. So right now, I'm not getting that much bass because I can't increase the sensitivity on the amplifier. Before the JL amp I was running a RF punch 500 and I didn't have a problem with the subwoofers rattling when I turned off the headunit. Would getting a pioneer deck solve the problem or should I get everything rewired or what? Thanks
*I had everything professionally installed at Pacific Stereo, a local stereo shop that is somewhat reputable.

Re: can't increase sensitivity on JL amp (fcm)
thanks. I had the hi lo converter installed when I first got my Rockford Fosgate punch 500 amp.
