I've got a box loaded with (4) 8" Eminence and (4) SuperTweets. On a lot of songs I play, my Mids/Highs will be screaming and are crystal clear but when the bass hits, they start to distort and don't sound quite as loud. Why is this? I'm running a Hifonics BX2005D at 2ohms's putting out a actual 1000-1100 watts and running a Kicker 650.4 off of only 2 of it's channels. I have stock Electrical sytem with 160amp Alt so I don't think running too much power is the issue. What could be doing this to my speakers?
