Small, Powerful Design
The S-Series amplifiers contain technology that was previously only available in Alpine's premium line up of amplifiers, the R- and X-Series models. The S-Series models are based on Alpine’s intelligent amplifier platform that ensures superior sound reproduction and precision imaging. With an improved heat sink, and protection circuit design that eliminates thermal shut-down, your music will keep playing no matter where your drive takes you.
Excessive heat is the enemy of amplifiers and under extreme conditions will result in most amps shutting down completely. PDR-Power amps use a special Multi-Stage Power Management circuit that continuously monitors critical component temperatures throughout the amplifier and decreases power output if anything gets too hot. If you are playing music under heavy loads for long periods, the circuit automatically reduces power output slightly at first, and then further in a second stage if necessary. This two-stage approach provides seamless, interruption free listening experience for non-stop music playback.

|Was a bit skeptical prior to purchasing this amp but the installer told me don’t worry, you’ll love it. I currently have a Hifonics Brutus amp pushing 2 Fosgate HX2 12’s and it sounded alright. The car I have comes with pretty loud stock stereo as it is.. supposedly 300 watts. But man after they got it all hooked up and tuned the sucker, man this amp impressed me and I can’t stop bragging to all my friends the power this little champ kicks. Plus the installer told me he hooked up the 12s at 1ohm.. Honestly I’m no stereo guru but when he cranked it up the car came alive! So me of course being the way I am I bumped all the way home for at least a good hour and the amp was just warm, not even hot! WOW! I have to hand it to the folks at Alpine, they have gone above and beyond with this amp. The certificate also gave me a rating higher than what the box advertised. Not to mention the sound was clean, no motor noise or whine and no clipping. Very impressive. I didn’t purchase the amp from this website but man I just had to put my 2 cents. If you’re looking for clean sound take a look at this little champ, you can’t go wrong, YOU will be happy with this purchase.

|I've had 4 other 5 channel amps and all about the same rms power ratings, but this amp seems to really put out some amazing power ( hard hitting, loud ).
I paired it with a Kenwood DNX691HD and 4 Infinity Reference speakers and two MTX Terminator subs.
I used sound deadening on both sides of the inside of the doors, which may have helped with the hard hitting experience.
I didn't tune the gains or crossovers because it sounded so amazing just as it is.

|This amp kicks ass. I have two pairs of pioneer coaxial speakers and a 12 inch kicker connected to it. The gain on the sub channel is set lower than normal. I should easy be able to add another sub to it with no problem. The clarity on this lil monster is the best I have heard in an amp no noise. I don't even have a great source feeding it cause I am using the factory stereo
