Great Buy!!
I purchased this amp to run 4 Pioneer TS-A6995R 6x9s in my 2002 Toyota Camry. I upgraded all my speakers from stock and purchased this amp & I've noticed a huge difference!! I love the settings this amp has to offer, sleek design, but most importantly, it's CEA-2006 Compliant. Normally rated at 400w RMS, my amp came rated at 568w RMS!! So at 4ohms, I'm pushing around 84.75w RMS per channel, which is how I have my speakers wired up. At 2ohms, it pushes around 142w RMS!! I would definitely recommend this amp to anyone looking to upgrade their stock speakers and need an amp that's gonna push!! Also, this amp was small enough for me to fit it on my backseat between my secondary battery and my other amp for my subwoofers.

Worth Every Penny
This amp provides outstanding power. I had the previous version and really liked it. This newer version is even better. A must have for anyone who enjoys quality in the sound of their music.

Awesome amp!
This amp is a great amp. It was a great buy and the built in clipping detector is awesome!. This amp I had on a set of rockford door speakers and the sound quality was amazing. The only thing is it doesn't have outputs. If your looking to get this I would recommend just getting the punch 600 4 channel so you got the extra power if you ever need it and it has outputs. If you don't need the outputs or the extra power this is still a great amp to buy and I recommend!

Good job Sonic Electronix
There is a reason Rockford Fosgate is still around and the products are CEA compliant.

Disappointed
I am using this amp to power dynaudio 3in mid and sundown tweeters and unfortunately this amp just doesn't come close to producing the power to run these 4 speakers. For stock speakers or cheaper coaxial it would work great but not for solid components. The anti clip features are cool but unfortunately add others issues.

Great amps from Rockford
Rockford makes some excellent amps, I always recommend them and use them. I've had several of them and this one is great as well. Especially with the CLEAN setup procedure to prevent clipping. Great amp! buy it! Great price too
