The PRIME Choice

Rockford Fosgate amplification at an unbelievable value. The R150X2 2-channel amplifier pumps out more than enough to power a set full-range or component speakers, or you can bridge it into a 4-ohm load to produce 150 watts for a single R1S410 10" or R1S412 12" woofer.

Class-AB

An amplifier topology with the best of both worlds; a Class A preamp and Class B output stage. Class A topologies area great for sound quality but can require alot of current. Class B designs are great for power delivery. Amplifier designs utilizing a Class A/B topology reaps the benefit of great sound quality in the front-end (preamplifier stage) while delivering great power in the output stages (MOSFET drivers).

good amp

I originally bought this thinking I would use it for front speaker in my 11 Malibu using the factory head. I paired it with some infinity reference component speakers and it sounded good. I ended up buying the 4 CH amp and upgrading the rear speakers with some jbl's. Now it sounds very good. I'd reccomend a Rockford fosgate amp to anyone. No problems connecting my factory head. I may use this amp to add a sub woofer.

What A Band for the Buck! - 2002 Ford Expedition

Title says it all and the Sonic Staff was great. Limited rear panel space with factory enclosure to work with, so the guys set me up with this amp and a Punch P3SD4-8 - perfect match and didn't oversell me on anything! Replaced a failed MACH audio system amp, running it mono and outshines the factory installed system. People can believe it's a single 8" sub but with the specs on this amp, I have some room to grow and options for another home. Love the tuning flexibility as well.

I did yank a star on Ease of Use as I battled with the remote - wouldn't play nice with the factory head, even with a solid state relay pumping a 12V signal for turn on. In the end, good reason to upgrade the head to a Pioneer AVX-4800BS. Happy as a clam ... for now. I smell upgrade(s).

Thanks guys - my one stop shopping from now on!

Great bang for the buck!

Bought this to replace an old 2 channel amp that died. Have this driving a set of Polk components in the front doors and they sound great! Amplifier is a nice compact size and fits nicely behind the back seat of an F150. Would definitely recommend for someone wanting nice sound without emptying the wallet.
