infinity kappa perfect 6.1 bass question.

tbone587: i have the SAME setup as you i have the perfects 6.1 with the 9831 HU powered by ALpine mrvt-320 what i did was set to the HPF on the DECK at 80HZ it gets very loud and the woofers in the DOORS really move they dont distrot hell i can feel the air it moves on my feet. i was messing with the bass focus on the deck before i got the sub i had the bass focus at like FL at  10 and FR at 10 it sounded very good nice mid bass. they use to move very well and still do now i got real bass with my nice 12inch sub. Also turn that MX feature off they just make the speakers distrort by turning that MX feature on you do get more bass but my components tended to distrot easier. any more questions ask me since i have same setup for front stage as you.

PS you may want to bridge that amp of yours it can give ur perfects 100WRMS*2 @ 4ohms. much better than ur 40WAtts atm this could also be why they are distorting just try it out and see what happens.

I don't think this is good advice.  40 to 100w is a not a large increase in power.  Certainly not, "much better."  blg748, you do know that this increase will only yield a MAX INCREASE in spl of 3db, right?  You know this is small, right? Furthermore, if he is in fact bottoming the speaker out with 40w, 100w has the potential to cause EVEN MORE DAMAGE to the speakers.  Not a good idea, in my opinion.

If he finds he's actually clipping the amp after checking that the gains are set correctly, then by all means, increase the power to gain more headroom.  However, based on everything he has told us, I highly doubt that is the case.  This sounds like a good old example of a 6.5" being asked to play beyond its physical limits.
