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.

Nice mid/highs amp

I would recommend this amp. This is a nice amp to connect to your mids and highs. Provides great sound quality

A high quality product and great price!

The Rockford line of car audio products have been a longtime favorite of mine. And thanks to Sonic, I can continue to enjoy high end items that last for a very long time. Thanks Sonic!

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

Clean power beast

Arrived on time, great price and customer service from Sonics as usual.

I have 2 other Punch amps and I ordered this one to power my 4 punch pro tweeters. These amps deliver clean power and don't get hot. Excellent quality and very reliable.

Amazing RF power

Installed this amp to power my front components and rear speaters in my car. The CLEAN setup is genius and this amp is clean and powerful. If I turn up the volume it pumps clean and clear power to my RF punch components. Perfect amp for my setup. Would highly recommend Rockford Fosgate. I have always used RF in my cars since the early punch 45's were around. The amp had over 500 watts of RMS on the birth sheet. Can't find any negatives about the amp. It's Rockford Fosgate so not much to dislike.
