Great little amp

i bought one of these from here a while ago, I hooked it up to a 12" alpine type R and it sounded GREAT! it was a tad more than i wanted to spend, but this amp gives you a true 600 watts RMS

Great quality

I bought this amp off sonic about 2 months back and i have it hooked up to 1 type R alpine 12". It has plenty of power and sounds great. It pushes my sub with ease. It has more power then you need and the sound quality is amazing. You cant go wrong with buying alpine products.

I purchased this amp and have it pushing two Pioneer TSW306 12" speakers and THEY POUND! I had the gain on this amp around 2/3 of max and I had to push that back, it is around 50% now and it sounds GREAT! This amps feels and sounds like it hits much harder than 300 RMS to each sub! All of the bass is clear and smooth, there is no distortion at all, no matter how high I turn it up. This sounds great and makes my whole car shake. The amp is very easy to set up and has a great design. Alpine is quality audio and this amp is no exception. Highly reccommended!

I got this amp a while ago and its awesome. You can't ask for a cleaner sound... Plus it packs a punch...I put this against a 750 rockford and a 750 kicker, it just blew them away both going to the same JL subs... I had it with some kicker 15's but I sold them when I got a new car... I am about to hook up two alpine S to it.

these are some crazy amps.

I have a buddy who has two alpine type R's and has one of these amps hooked up to each of them...
short quick and to the point, WOW! these are some bumpin amps. since he has gone all alpine he has a subwoofer controller in his head unit therefore the amps dont need a bass controller. but these will rattle your trunk and have you leaving the car with the feeling of the bass still thumpin when in reality its over. for a crazy experience these amps sure power the R's beautifully.

for other questions he was using a capacitor too.
