Insane. I've heard two L7's hooked up to each of their own amps with caps and mine still sounds better and louder with this amp and two Audiobahn ALUM12Q's. I would recommend this amp to anyone who wants a loud system but also still wants it to sound good. Incredible difference from all other amps.
Great amp. I've had it hooked up to a 6 speaker system in my mustang for a year now, and it has been amazing. I bought mine through work, and dealer cost was more than this (I am in Canada, though). Hell of a deal. I plan on replacing the 6x9's with two Boss 12" subs soon, and this amp will power everything.
I had two bandpass boxes from Dual, two 12's in each box. At first I ran them off a Kenwood 1000 and was thinking I needed better subs. Not after getting this amp! This thing slams and if the soung is right, it will open the trunk of my 91 Maxima. Higly reccomend this amp for bass though I dont know about coxal systems.
