This is one of a few SSL amps I got and I’ve been satisfied everytime !
I use them myself and also for friends. I have one of hese installed under the front left seat of a Nissan Navara and the fit is great. Love the simple crossover and the sound is enough for a single 12″ shallow sub at 400W rms. The Pioneer TS-SW3001S2 can handle 400W rms with it’s single 2ohm voice coil and this amp slams it good !! Could not be happier.
