how? did the sub pop out of the box and fly out the back window? no offense...but if 30k of power, 4 18's and mid-high 150's in a tahoe doesnt shatter a back window, i dont see 5k of power on 4 12's doing it. just my thoughts.2000.1 DD
my cousin has 4 DD 12s in her tahoe with 2 2500.1 DD amps and she has shattered her back glass twice and jacked up her mirrors, window seals
DDs well worth the money i say they beat kicker 2 to 1
I meant soundstream :/ my badThere are lots of quality audio companies that make great sounding subs and amps. Look at soundstrem, powerbass, elemental designs, hifonics, infinity, jl, and pioneer. All make good stuff. Id try to stay away from department store type speakers and amps like the alpine,kenwood,and pioneer junk they sell at best buy lol.
