Great amplifier for the money!
So far this amplifier is pretty impressive. Makes tons of power and looks great. You will definitely need to upgrade your electrical a bit to safely run this amplifier an extra battery to support up to 3000 watts RMS.

Shop for better
Amp lasted less than 6 months. Speaker output quit without any signs of fault or product misuse. Device looks pristine, all lights and switches function as they should but simply no speaker output. Tested wiring and used alternate device to verify issue is this amp. Unit is trash since I purchased no warranty. Never had an amp fail so quick.

Probably worth the money...
Integrated this into my car audio system and while it works and is probably worth the money at this price point, I'm not impressed with it's output so far. Highly questionable that it does 4000 watts RMS at 1ohm. Just saying...

Garbage Chinese Junk, buy at your own risk
Hifonics used to be a great brand but over the past years their quality control has just been garbage. The last 2 Hifonics amps I’ve ordered were both defective out the box! Including this one! Paid almost $300 for this junk and Amazon only gave me a $235 refund! Don’t know what’s up with that! Wouldn’t even give 1 star if I could. Will never buy anything made by Maxxsonics again! Buy this AT YOUR OWN RISK!
