Power House

I would recommend this product because it has lot's of power clarity and Sonic control included in one package

great power

more than happy with this amplifier. It's rated at 2x 100wrms @ 4ohms, it birthed at 2x 149wrms @ 4ohms. Massive power from such a small amp. Bridged into 1 channel @ 4ohms its putting out 498 watts RMS!! amazing little thing

Beastly

I bought this amp to power my Alpine Type R component speakers. This amp is so clean, easy to set up and never gets hot no mater how loud I turn up my music. Granted I'm not bridging this amp for a sub so I'm not even using it to its full potential but I am more than satisfied for what I bought. I have complete confidence that this amp will last me for years. Rockford fosgate really knows their stuff.
Excellent for powering a pair of high end speakers or maybe some entry level subs. I would recommend keeping it to 1 sub or 2 entry level subs. because bridged only makes up to about 500watts at 4 ohms. But it can handle any speakers and have perfect clarity!

wow!

this amp is wonderful! i have it installed in my boat running some kicker tower components and it does the job and then some. i really like rockford amps cause they are way under rated and you will know when you get the birth sheet what i mean.

Best little amp ever!!!!

I use this amp to power a single 10" RF power series sub in my 02' Altima and it hits really hard with plenty of power to spare. I turn up the music and can feel the bass in my face, chest, hair, etc. I would recommend this amp to anyone out there in need of some serious power for their subs!!!

Awesome amp!

I bought a boss amp and it crapped out after a couple months of use. Then i bought this amp and it bumps harder and lasts longer. I havent had any issues with it. Definitely worth the money.
