Pioneer avh 6050dvd Head unit
1 Polk Audio sr 6500 (getting the other pair probably)
2 JL Audio 13w7
1 Alpine pdx 1.1000 (hooked to 1 sub, getting another amp of this)
1 Apline pdx 4.150
The subwoofers sound pretty nice but... When I need it to be loud it produces some kind of weird noise (not in every song). Ive been researching and it is maybe because of the poor signal strenght... the head unit is pretty nice, it has 4v preamp, but the RCAs are 7meters long and ive been thinking that there must be the problem... If there is... What should I do? a buy a subwoofer processor? like the Soundstream Bx-20z? or the Powerbass Xba-2? or the kicker KQ30? all of them increase the preamp power (In case that it is what Im needing) I want SQ and some strong bass... If there is anything you know about how to improove the SQ, please let me know, my speakers signal might have the same problem even when they arent distorting much...
Thanks for the help...
