    • LOVE IT!
Still driving a set of Kicker CompVR 12's with no problem. Love the clipping indicator. What else can you say about this thing, it's the low end model but it hits hard, works reliably, and just gets the job done without any fancy fluff. LOVE IT!

    • Did work great…
I bought this amp in July of last year and it WAS awesome. But today (Feb 25) I turned on the stereo and it immediately went into protect mode and jumped back and forth from power to clip to protect. The amplifier gave me seven months of good loud music, so I’m leaving 4 stars.

    • This amp delivers
Paired it with a sundown 15” sub. Did big 3 upgrade, AGM battery, and 320 amp alternator. This amp delivers the power!!! Shaking my poor Jeep to pieces. Great sound quality. Performance is as advertised. Good value for the price. The bass knob is nice, too.

    • Refunds take forever
This is my 2nd amp from these guys and the first one I sent back and still haven’t received my money 2nd amp is great. Give me my money back! Update: don’t buy caught on fire almost burnt my car to the ground before I got it out, a little background info, I have an JS high output alternator and two Agm batteries, along with 0/1 OFC big 3 upgrade, and complete OFC wiring throughout, subs wired to 1 ohm, no reason this should have created enough heat to catch fire! ... show more

    • Great if you know how to use a high wattage amp.
I have this powering two Sundown 12" subs. I have this hooked up to XS power AGM battery and IOXUS 12V Group 31 Smart Power Bluetooth Car Audio Ultra Capacitor UC-31 using 1/0 welding cable. This amp doesn't even get warm. I'm guessing the people having fires are using copper clad aluminum wires and stock powers sources with too much draw on crappy power systems = HEAT. This is a 3000 watt amp and no your stock electrical will not power it safely. Do the Big three upgrade and use proper OFC 1/0 wire with extra power source like XS power Batteries and Ultra caps. ... show more

    • DO NOT BUY.
I have purchased 2 of these amps, the first time was definitely my fault the speaker wires touched and dead shorted, not complaining about that situation. Although the 2nd amp I got threw itself into protect out of nowhere , I crunk up my vehicle and the amp was in protect , everting was just fine the night before. I don’t believe this is a true sundown amp… sundown does not offer this amp on their website , the biggest SFB series amp they offer is a 1800. ... show more
