  • 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.

  • 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.

  • Internal Issues Beware of Fires
Purchased this idem to put towards a 3000$ build. I get all my idems in just, just to have it installed for the amp to power up green for 1min, then crackle smoke and burn out. Sadly im passed the return window now and sealer will not refund ANY money they will ONLY return for repairs. I had high hopes for this compact sundown style amp but beware this is truly unsafe even with your fuse blocked in-between 12-14v power supply's. ... show more

  • 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.

  • 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

  • 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

  • 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
