Heavy for such a little amp 😲

Bought this amp with the matching 4 gauge CCA amp wiring kit and put a 100 amp anl fuse in the provided fuse holder under the hood.. have it pushing an 800w rms Deaf Bonce Machete Fight S D2 and this 400.1d is giving the Russian sub one helluva workout.. sounds absolutely amazing and doesn't break a sweat.. CT Sounds has exceeded all my expectation with.. their quality,performance, value, customer service and shipping cannot be beat.. truly the best "BANG" for your buck

Bought this amp and put it on an IX Skar 10 running at 1ohm… I was surprised and what the amp could do.. brought that 10 to life! Also used the same amp to run a a Skar SVR 12 at 2ohm… basically giving the sub half the power of the rms and it sounds great! I’ve gotten many compliments.. plan on upgrading in the future to the 1000

Great Little Amp

It's really working a single Meso 6.5 D2. Great adjustability and sounds clean. Awesome deal for a solid 400 watts and then some!
