Great Amp! Great Features! Great Price!

I have owned & purchaed several MB Quart amps from Sonic Electronix! I like MB Quarts quality, ease of use features & great price for the amount of power. I bridged this amp running mono to a 12" Kicker Solo-Baric L3 running 400 watts RMS & sounds great inside the ported 12" square MDF (Prod.#1SVK12) box. I would recommend this to anyone who wants to add some bass to their system.

MB Quart RA400.2

This amp rocks in both style and function. I have it bridged on a RF R2D2-10 and it is KILLING it!! The built in sub sonic control is sweet and lets you dial in the punch you want. I would recommend this amp to anyone looking for style and performance.

Overheats under light load

I would not recommend this amp. I've had a elemental designs amp for 7 years before it gave out. I bought this as a replacement. It paired up well for what I was going to use it for. I'm powering a 400w rms sub @ 4 ohms. I installed it in a well ventalated area and when I had a song with loud bass it overheated. I wasn't really even pushing it that hard. It does have a protect feature but it gets far too hot under load.

Small amp good power great sound

I put this amp in my boat and it's pushing a 10" jl wov3. Great sound good output. I would like more bass but its more than I expected out of the sub

Great value for the quality amp

Rock solid bass out of my single MB QUART 12" sub. Very clean low bass. Highly recommend.
