Summary: Great amplifiers best quality I ever heard and is so sample to install and so compact, never saw something like this. Bought the powerful PDX 1.1000 with the insane total of 120A fuses which has a lot of configuration, even a subsonic filter. And a PDX 4.100 which just impressed me with the crystal sound compared with my previous amplifier of A/B class. Very crisp sound and good quality even if bough used.

Conclusion: First time I had committed to a high end amplifier I was optimistic yet apprehensive. Happily the PDX-4M ROCKS. My jeep Cherokee has two 6.5in component speakers in the front and two 6.5in in the back doors. Both sets of speakers are alpine type -R. This small cool-running very powerful amp tests their limits. I highly recommend this amp.
Conclusion: I purchased this and a PDX 5 for my boat and could not have been more pleased. Alpine makes a rock solid product. I get endless positive comments on my marine sound system that is completely Alpine. Thanks for making it so easy.
Summary: This amplifier is the best. If I had to pick one feature i like the most it woul dbe the connection interfaces. All wiring is done by stripping off the wires and putting the raw cable into a hole that is clamoed down by an allen wrench. Thee is not solderin necessary, and you do not have to put ends on your speaker wires. Plus the adjustment knobs are on the front of the amp. I have it installed under the bavck seat of my Ford F-150 and o live it!!!
Summary: I love this amp, works great, and man it makes my boat super loud with the speakers I got off ebay also. I run two of this amps and I'm going to get one more, I need more speakers in the boat.
Summary: I love everything there is offer for an Alpine Amp. i recommend Alpine products for anyone that wants to hear there components loud and clear and very smooth. Amp is the best i've heard for the price and size. wouldn't ask for anyone to buy anything other.
Summary: This amp is so nice, I ended up buying two more after my first purchase. It is digital and does not heat up at all like other amps. It also has the Mosfet technology and has pure clear powerful sound. It is very versatily since it can be bridged from 4 100W speakers to 2 200watt speakers all the way down to 1 400W speaker. I am using it for 8 speakers and two 12 inch subs. Wow, it is a fantastic amp.
Summary: simply an awesome amp. rated at more than is is advertised at. certificate comes with it about the rating. got mines brand new. i did a lot of reading up on this amp. and it surpassed what i expected. this is a must buy if you are looking for an amp like this. you will not be disappointed! only thing i kind of dont like is how the terminals for the wires angle downward. kind of stretching the wires in an upward angle. this is the ONLY downside I found.
Summary: I INSTALLED THE PDX4-100 IN A 2003 F-150 EXTRA CAB , IT BROUGHT THE AFTERMARKET ALPINE SPEAKERS TO LIFE , CLARITY , BASS , MIDRANGE AND TREBLE ARE ALL SO CLEAR NOW , NO HISS , NO CRACKLES , JUST CLEAR LIVE SOUNDING MUSIC. I WOULD HIGHLY RECOMEND THIS AMP.
