I am going to ask this even though I believe I already know the answer. Should I just set the X-over on my deck and leave the amps off? The reason I ask mainly is because I don't want to blow another sub. Just last week I nuked my "D" series solo. I was running it with a PPI PC2150. Looking back I know what did. I set my Qbass cross over to a specific frequency(36Hz) and then made the crucial mistake of turning up the Qbass bass boost too high. While running through a frequency sweep I hit 36 Hz and poof!
So here I am again having just found another D series solo. I plan to go with something new sometime soon but my entire trunk install was geared around this sub(tiny box, with sub and amps flush mount in trunk floor). I lucked out and found another one and I will use it for the time being. Not wanting the kill this one I know the first thing I should do is turn down(off) the Qbass bass boost. But should I turn off my amps X-over all together. I am running my system with an Alpine 9831. It has internal high/low pass x-overs as well as a 4 band equalizer. Should I just stick with my decks X-overs and just let the amp supply the power like it is supposed to?
