Just say 158.6 on audiocontrol with 2 amps street c legit. This is what i told people make sure your equipment you use is good and not broken. just say new batts, new amps descent pair of 15" subs and a good vechicle and no malfunctions and thats what you get. We will have to wait and see what it does with 4 real big amps lol and better subs maybe a pair of TF1 subs lol.
