Good deal

I recommend Sonic Electronix to anyone. Good quality merchandise for a cheap price.

Good value, good looks

Good features, good looks, good power for a good price. I like the RCA output to allow more amps off of one set of head unit pre-outs. Pushing two pair of 6.5 coaxials that allow them to really shine. Have not run into any overheating issues. Would recommend.

Great Amp!!

I bought this Amp in 2015 this well the older model this is the next model pretty much the samething. this amp is really good no problems what so ever I am using the amp on 4 Rockford fosgate T1682 and even with or with out the amp the speakers are amazing! This amp is worth getting.

Bang for the buck

This amp has very good sound reproduction and usable adjustments.
The bright blue led-logo lites up the hatch of my '18 Impreza. Speaker-level inputs are a nice addition also.
This product didn't exceed my expectations, thus a four-star rating.
