Review written by Mike from Western Massachusetts

I have a sub compact car (Toyota Yaris) and this small workhorse packs incredible wattage and headroom in a little package that fits easily in my hatchback. The sound quality is great for a Class D amp, I would recommend it to anybody except the pickiest of audiophiles

Review written by Piotr from Seattle, WA

After being out of the stereo world for quite a few years, I wanted an amp that was easy to tune, had the power & ground separated, but most of all sounded great.
I knew that I would be mounting my amp in a tight location so heat could potentially become an issue.

After doing a little research and narrowing my choices to the JL 500/5, Boston GT50, and the Alpine PDX-5, it's obvious the choice I made. I'm not an audiophile so I found the JL to have WAY too many adjustments and I wasn't pleased with the staging feature of the front/rear power rating, but the sub rating was good. The Boston was simple, offered a good sub rating, but the front/rear wattage was a little low. BOTH amps were a little large and to my knowledge are NOT digital amps so heat could be my issue.

The Alpine, which I didn't find many people on car forums having, seemed to be the better choice given my requirements. I'm running 4 Boston 6.5" coaxials, and a 12" Boston G3. I also have a 2 farad cap.

I have this amp hooked to my Infinity 6.5 in my front doors and back deck lid and they are loud and clear. If that is all the amp could do it would be worth every penny but its not i hooked my 2 jl w3v3 10's to it and they bumped nice. They were underpowered but still sounded nice. If you don't want to upgrade your alternator but still want a loud clean system then this is the amp for you
