    Missing Attachment Kenwood has built their reputation in building car audio amplifiers which offer outstanding reliability and advanced sound quality.

    Allright. I bought this amp about 1 month ago. Wicked cheap price. Brand new in the box.. Opened it up and stoked to see how beautifull and sleek it looks. Anxious to see it perform i brought it to my car immediatly and spent the rest of the day fiddling with it.. / the last month. heres what ive experienced so far. First off my wiring from battery + terminal is a 5 gauge scosche wire with a 100 a fuse in it. Goes to my trunk, then is split by a block into a 8 gauge... Read more

    Have 2 of these hooked up to 2 12" premiers 3000 watt subs. Powers them very nicely wired to 1 ohm. I used to have 2000 watt 2 channel but these beat it by far. They are not a good as other brands of the same watts, but for half the price or more it is alot better deal. Read more

    I have 2 12in. Kicker CVX's with 2 ohm DVCs and I have a KAC-9103D but that amp wasn't enough for the 2 subs, so I got this one so the amps were similar. All I can say is "HOLY CRAP!" This amp is definitly powerful. With both subs, I have talked to my friends after I have sat behind them at a red light and they said that I'm rattlin' their car too. Really I can't really describe the power of the amp unless you experience it but again, all I can say is "HOLY CRAP!" Read more
