Summary: I installed this unit with 4 5'8 pioneer speakers in my ranger, bought a pioneer radio from bestbuy for $130 before the amp my music wasnt clear when the volume was above 30 but now with the amp i can have it turned to the max and have crystal clear music, this amp does bot work well with subs it can barely power my 8 inch sub and its terrible i only recommend with speakers.
Summary: This amplifier delivers exactly what it advertises. The four channels, with option to bridge, gives you options. This amp is greast for people looking for a low power amp. It is great for front and rear speakers, but is a little underpowered for most subwoofers. If you want to power a subwoofer, you'll most likely have to go with a higher model (depending on your subwoofer specifications).
Awesome amplifier; if you can get one, snatch it up!

Summary: I think this amp has been reviewed before, maybe there's a mistake. Anyway, I love this amplifier so much that when I got the chance to buy one that was a return to where I bought my first one from for $107.00 I jumped on it. Just to have it; I still have it in stock in my closet with my other equipment.
Running your mids and highs? This is all you need.

Summary: I have this amp running a set of Infinity Reference 6.5 coax and Infinity Ref. 6.5 components. This amp plays loud; even if you double the power, it only goes up a few db. In electronics, to double the db. you have to add 10 times the power, so another 20 watts or so won't make much difference, so don't let the 40W per channel fool you; it's loud.
Summary: Great amplifier all around. Power rating seems a little lower than others currently available, but at 40 or 50 watts, respectively, it does an amazing job powering my Infinity Kappa speaker in my convertible.
Summary: Alpine car stereo products have always been high quality. I always seek out the Alpine name when shopping for car stereo components on eBay. Even used, Alpine products are a good deal because of how well they are built.
