MB Quart FA1-200.2

MB Quart Formula series two channel car audio amplifier featuring innovative sound quality and power technology. The FA1-200.2 is a 200 watt bridgeable car audio amplifier. Formula amplifiers feature DC Sensing to allow any amplifier to be easy integrated into an OEM system by simply adapting a RCA cable from the source unit.

Good Little Amp

I bought it as a birthday gift for driving a single NVX VSW122 sub to complement a factory system, and it works well - birthday girl is happy, no complaints. This amp has a lot of features that others do not for the size and price. I bought it for two reasons: 1 ohm stable with a small fuse rating (low current draw), and DC sensing on the RCA inputs (no need for a remote wire) . I used a Rockford Fosgate high level adapter to tap into the rear speaker lines, install was easy and no line output converter needed. I looked at a lot of options before going with this MB Quart, and I am pleased with the ease of install and power output.
