do not be fooled by the size of this amp it has blow my rockford fosgate p3 15 easily

This amp is ideal for intalations whereby space is an issue or can not be compromised. With this amp I replaced an old alpine Amp that was also in the class of small powerful amps. I made a switch and noticed and inmense difference. It was so intense, that I had to dynamat the car panels. I was powering a JL w3 12" on a sealed enclosure and the sound was incredible. The bass was clean and deep- for its size unparalleled. This lasted about 8 months. Unfortunately, the speaker was blown. However, the speaker lasted about 8 years under the old amp that had speaker protection. I then purchased another speaker. I tried an Alphasonic 400 series as a temporary fix. This speaker was also blown out in only 3 days. Apparently, there isn't any speaker protection built in to this device. Also of concern, is that the gain controls are not easily accessible. It is bellow a face plate on the top of the amp that is screwed in. I just dicovered this after consulting with a JL salesperson. Now, I'm in process of trying the RE Audio SEX 12 sub that is favorably reviewed by Sonic consumers. Wish me luck. I guess with proper gain control and the right combination of speakers it is a good little amp. I recommend it, with the exterior device sold separately to control it's volume.

Very good unit in my opinion. I'm not a SPL guy, so I'm not sure what "cold" means. I previously owned a RF Power T500-1bd. It was a good sounding unit, but this amp sounds just as good in my opinion. Plus, JL Audio includes detents on all their adjustments, which surpasses any RF amp I've ever used as far as tunablity goes. Long story short, both amps are good, but if I where to recommend one over the other, I'd take this one. They cost about the same.

Just finished installing this in my car. This amplifier is so TINY but yet so powerful! My JL W6v2-D4 never sounded so good! Sonic Electronix delivered fast!
