    2 out of 5 eggsNo way 400w RMS

    Pros: Works. Looks nice. Cheap.

    Cons: The amp in my Sony header has more power than this.
    No way is this 400w.

    Other Thoughts: Keep looking unless you never turn up the loudness. Be prepared to buy ground loop isolators.

    5 out of 5 eggsGreat Amp

    Pros: Perfect for my setup, accepts 4 gauge ground and positive, sounds terrific i have it powering 6, 6.5inch speakers and it sounds great.. low pass and high pass filter works well also. does not get hot although i do have a cooling system. fans. and for 46 bucks... its a steal

    Cons: i get serious ground loop hum and alternator noise.. it give me a head ache.. i tried everything to get rid of it but to no val. i got some nice ground loop isolators and it fixed the problem. also make sure do give this amp enough power.. or i will distort

    Other Thoughts: would buy another sound storm product again.
