If anyone has ever been to a Metallica concert and can acheive sound quality close to that,then your in audiophile heaven.This extremely difficult in a vehicle without extinsive sound deadening and high quality equipment with the right installer.I wasn't impressed with a recent install to say the least.I let him install one amp and it looked like Sanford and son had done the job.Long story short,I never let another installer touch my vehicles.Xtant is hard to install if you've never done one but with some studying,anyone can do this.If anyone knows of a better amp,i'd like to hear one.Not saying their isn't one but I haven't heard it yet.
Alpine 9886 H.U.

Result:Audiophile heaven and pissed off neighbors.
