Awesome amps!

Bought 2 E400.4’s. One is running my front doors - Peerless NEO tweeters and Dayton RS180 mids. Using an Audiocontrol 2XS crossover. The second amp is running 6x9’s in the rear deck and a pair of One Audio 15” IB subs. These amps sound incredible and are strong amps weighing less than 4 lbs each. Glad I purchased these amps!!!

(2) E400.4 and (1) E1500.1

I held off writing this review until my new speakers were tuned and the system dialed in. Honestly I am very happy with these amps, the price point and performance. Using the 4 channels in 3 channel mode for left and right duties. Quite as a church mouse, no turn on or turn off noise. The noise floor of the amps are also fantastic. My amp rack is almost complete waiting for my acrylic to arrive.

Clean d amplifiers

Sounds incredible and produces more power than rated. Pair this with the 750.1 or the 1000.1 and you will be very happy with how good they sound

Bad ass amp E400.4

I usually don't do reviews much, but I had to do one for this amp! This is a lil power house and very clean too! When I installed it I left the settings on deck the same. Boy I had to make some changes. The amp is so powerful and clean I could turn it up more than the old one with more power! If you are looking for a new amp and you want the very best for your money? This amp will amaze you! There is no doubt you should buy this amp!
