  • 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.

  • 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

  • She bangs.... for 4 months.
I haven't even had a sub hooked to it for the past month, just a capacitor. We'll, I started my vehicle today and went inside... came back out to the most pungent electronic burn smell you could possibly bless your nose with. She gone. Protect mode. 0 sub hooked up.

  • 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.

  • Very satisfied.
Best performing amp I've ever had. Sound quality is awesome, as far as "value for money" I always say you get what you pay for. I paid good money, received a quality product. Thinking of buying another.

  • Good amps aren't cheap. This is well worth it
Great product. I have it running 2 Sundown SA-8's. I have the amp turned 1/4 of the way maybe less and its more than enough power for my subs. Sundown does it again 5 stars

  • Amp
I have mixed feelings about this amplifier. I love the idea of the clip light. It always comes on just once the amp starts hitting hard, so I have to turn it down SMH. The amp doesn't hit hard at low volume, you got to turn it up before it starts hitting hard. It most definitely stays cool! Does not cut off at all. ... show more
