[G.E.]

I've had a subwoofer installed in my trunk. I blew a type r in 2 weeks and a P2 in 2 hours. My audio guy has checked everything. He's installed many systems over the years and the only thing he can guess is that my stock boston acoustics system is sending the wrong signals (highs and lows and all that) and it's confusing the woofer to where it doesn't know what to do. Anyone else have this problem?
