F4

small and beautiful design can install in any location in car,powerful amplifier that use for any component speaker and low energy consumption.
setup it with hertz 3way mille component.very good sound.

Best 4 channel I've owned

This is by far the best 4 channel I've owned or maybe even seen. I've been doing car audio for about 8 years now and this thing is amazing. Best sound quality I've ever heard from an amp and puts out true power. This thing makes my surround speakers sound amazing and honestly puts out too much power for them almost need upgrade again for this amp but zero complaints at all. Would recommend to anyone looking to have a great system.

Great power for the money

I bought this amp a few months ago and absolutely love it. It's powering my mids and highs up front. The highs sound crisp and clear, the mids bang out some drum beats and they will get LOUD when I want them to. The space this amp uses is also a big plus as I have a truck. I've had no issues at all so far with the amp. I do wish you had slightly more adjustability, but I can't complain. Overall, a happy customer!

very nice amplifier

Great sounding amplifier, the class d design sounds every bit as good as my former soundstream and phoenix gold titanium seriers class AB amps. also bought it for its effeciency which is superb, nice small size and the installatioin is the best yet that i have used and i have installed many different amps over the years.

SOLID!!!

I do not own this amp, but I do own the predecessor and can only say it's still a fine amp! For the footpint, power output, and efficiency, as well as the price, you cannot beat this amp! Alpine quality and sound reproduction is almost second to none except for the extreme high end amplifiers (Zappco, Stetsom, etc.) but you will pay WAYYY more than this little guy! Dont understimate it!

better amps for the price

I really don't like giving products bad or somewhat bad reviews, but in this case I feel the need to. This amp has INCREDIBLE power. I truly love the sound of this amp; however, for the price, there are much better amps available. The biggest issue I have with this amp is the input sensitivity. The max input for this amp is 4v, which is decent for an above average system. If you have a stock head unit and want to run this amp, it requires an LOC like most other amps. For a little bit cheaper, I would recommend the Kicker 11IX500.4 simply because the FAIL safe integration and being able to run a high level input into the amp. Also the kicker has a pre-out for a separate amp incase you want to add a subwoofer. The kicker may only have 75 watts RMS @ 4 OHMs, but this is still PLENTY loud for someone looking for a clear, accurate amp. Of course these features and applications are not meant for everyone, but I just feel that if you pay this amount of money for an amp, there should be a lot more features. I do recommend this amp for anyone who is bias towards the Alpine brand, running this on an aftermarket head unit, and just wants a LOUD system. If that describes you then go with the Alpine. If you're like me and want to integrate with an OEM radio, then by all means look for a different amp like the example I gave of the Kicker IX500.4. Both amps are excellent, but the kicker has a lot more features and capability. I hope this helped someone out.

Sweet Amp

Tons of clean, crisp power! Great product

Better Than old school

Let me just start by saying I am very very picky..It take a great deal to impress me... okay... I was a custom installer for a high quality shop back in the 90's. I have done some very serious systems in my day. About 2 years ago I was looking to do a simple "low key" system in my new car. But I wanted it to hit hard and sound fantastic. Being I had been out of the Car audio loop for several years.. I was at a loss when I found out that ALL of the old school, high end, American car audio companies had bit the dust. Though some do still exist in name only... PPI, Phoenix Gold, Hi Fonics, ADS... ect...ect... But they are now Chinese made garbage. So on a recommendation from a friend. I took a look at the Alpine PDX series(Alpine has always made nice stuff). And let me tell you... These amps are BY FAR!!! The most musical, efficient, dynamic... And key word here... POWERFUL amps.. I have ever worked with. They are so far beyond anything I have ever seen... That even after 2 years... I am still amazed by these amps every time I fire them up. They are price wise.. In line with my "Old school favs" A PPI A600 and A404 I had in my 2 seat pick up back in the 90's.. But these amps are so far out of their league.. And that's saying A LOT!! If you are looking for state of the art... If you are wanting absolute car audio perfection. You will simply not find better. Alpine has really done something wonderful here. This line of amps are the simply the best the car audio world has to offer. Thank you Alpine!

Great amplifier

I admit, I was skeptical when I bought this amp because I wasn't sure if Alpine still made the same quality products they were known for back in the late 80s and early 90s. I was driving Alpine 6.5" Components in the front and 6.5" Coax in the rear of my F150. This amp never had an issue at any volume level. Crystal clear at wide-open volumes. I love this amp and am installing it in my new truck. Trying to figure out which components to go with. have narrowed it down to MMATS Pro Audio, JL Audio, and Sundown Components. All 6.5" component sets.
