4.0 out of 5 stars Very small and decent full range amplifier, October 4, 2007

By	Paul Barnaby (Bellevue Nebraska) - See all my reviews (REAL NAME)

This amplifier does very well fitting into tight spaces. I've never had any issues with it getting too hot. I did remove the shroud, it just looked too flashy.

I never thought I'd buy a sony made car audio product, but this one doesnt disappoint.

There is one thing that should be noted, in case someone doesnt take the time to completely read the specifications for this amplifier.... there is no front low pass crossover, only one for the rear channels. This means that it would be difficult to bridge the front and rear channels together to push two subwoofers.

5.0 out of 5 stars Perfect Fit, March 7, 2009

By	MrDrew77 - See all my reviews

Bought this amplifier after a few months of research for a low profile amp. And it has not disappointed yet. Installed it in a '95 Corvette behind the drivers seat, it fits perfectly and looks great. The sound is clean and powerful no matter the genre of music. I would highly recommend this amplifier to anyone.

Read a ton of reviews before I made the purchase, most of which were favorable. This is a rock solid little amplifier. As with most electronic items if they are not dead out of the box then they usually will work for quite some time so I cannot comment on it's durability as it's only been in use for a month. I can say that during installation one of the speaker wires was hooked up backwards (the imput to the output and vice versa) and the amp's built in protection saved the amp and the radio from any damage. As for the sound .. extremely tight and clean. I initially used the full range on the rear speakers and the bass was more than adequate but after installing the subs in the trunk I switched to the hi-pass option on the rear (there is ample adjustments for front\rear options). An excellent amp for the price and it fits in an extremely tight space under the front seat. You will not be disappointed.
