Just Perfect!

I really like this head unit. Installation was pretty easy. It has an unstopable list of features. It has everything I need. The sound output is very clear and the radio sounds well too. It is very easy to operate. And I really love the 2 color illumination.

good deck for the money

It is a cheap deck that has a good preamp output and I don't have any speaker running directly off of it but it says that it can give them some power. It is in my 1996 grand am and I plan on replacing it with a Panasonic deck but for now it works and I like the fact that you can turn your sub on and off.

The BEST sound at this price range!!

I came across this headunit and was instantly in love. Everything it does and how well it sounds for this price range is incredible. I've been rocking out with it for 2 years and have had it cranked pretty much that entire time. I would reccomend this headunit for anyone regardless of how careless or picky they are about their audio if you don't want to spend an arm and a leg on a high-end headunit. Kudos, Boss.
