I waited over a month to review just so I knew the amp and could be accurate.
The amp is well built and has not given me any problems running at 1ohm in a daily driver with big 3 upgrade and otherwise stock electrical. The amp does not get hot and sounds good but I do have to set the gain to nearly 1/2 to get decent power (could be I'm not getting enough current to the amp but no issue with dimming headlights etc)
I am running this on 1 American Bass XFL dual 2 ohm and the sub actually wants more. Make no mistake it destroys a low note and moves a ton of air (and sheet metal) w/ the one 12 port tuned around 32hz. The crossover built into the amp is a guessing game like most amps now it says something like 50-230 so setting a precise x over frequency without a external crossover is a bit of work.
Bottom line for the money you can't go wrong! American Bass makes great products that will rip your car a new one without having to spend more than your car is worth as with the higher end brands.
