Poor fidelity
The product is OK for a kid, or for a very noisy environment, but not OK for a discriminating ear. I tried this route because I was trying to put the amps under a cover, I thought they would stay cooler. Nope. This guy gets hot. I would recommend to some, but not others.

I have had this for a couple months now and it works great. I had to send it back for replacement after a week of owning it, not really sure what happened. Rockford fosgate is a reliable product usually but the first one started smoking after I had been using it for a while. Sonic electronix replaced it and it works great now. I do recommend buying a amp fan to go with it because it does get very hot after long periods of time. Sounds great though.

Great highs amp for powering small speakers. That's all I use it for and it's not even at the 12 o clock position. I would recommend it. Also I like the fact that it's compact in size.

I have been wanting to build an all Rockford system for a while, I knew I wanted to run a sub and four new speakers (All Rockford) but didn't want to buy two amps. This amp was the answer, pushing 500 RMS @ 2 ohms (according to the birth sheet) this thing rocks. I have two pairs of 4-ohm Rockford 6.5s running at 2-ohms bridged. So they are getting a good 65 RMS each, and they produce great highs and mid. For the lows, I have a DVC 10" Rockford sub that's being pushed a good 250 RMS. The sound is amazing, highs, lows, mids, everything all in perfect crisp harmony. This amp is absolutely amazing, not to mention its a perfect size. All my friends find it hard to believe that this little amp pushes so hard. Worth every penny!

Mated the Rockford Fosgate R400-4D to a Pioneer head unit. Wow! Amazing sound. Loud. Crisp. Clear. Everything you want in a sound system. Fits perfectly under the front driver's seat. It sounded great out of the box but is absolutely superb now that I've been able to tweak it a little bit. Installed the amp using an NVX Audio XKit44 with 4 gauge wire 4 channel connection kit. Stop reading reviews and buy this amp.

found this helpful.Excellent Amplifier
Got this amplifier to power my six speakers in my '99 Camaro; it does an excellent job! Ran the two rear pair in parallel and made a custom MDF rack to mount both this amp and the sub amp on the trunk deck just behind the back seat. My only frustration with the amplifier is the angle that the wires have to enter into the terminals at; they wires have to bend upward. It's just less convenient than having terminals coming straight out of the amplifier.
As far as sound quality goes, this amplifier brought my Rockford Fosgate Punch speakers to life! The clarity is brilliant and the crossovers work splendidly. I am very pleased with my purchase and will always look to Rockford for car audio components.
