sorry does your amp put out 800 watts right now and you want another 200 watts? if so, you're a ****ing TOOL

thats only .75 more dB than what you have.

COMPLETE waste of money.

unless you're only at 400 watts in which case just over 3 dB is worth it.

LOOK AT USED AMPS.

greatest deals are in used equipment since all car audio **** is overpriced as ****.
