Review
I have been upgrading my sound system for the past 10 years, trying many different decks, speakers, sub woofers and amps. This is a great sound processor that enables the full sound shaping capabilities of your deck. I currently have a competition equipment all the way around and I thought that finally I had got the perfect system prior to getting this component, but I was wrong. If you have more than one amplifier in your system you need this unit, it features a crossover that will do wonders for your sound system. If you like to tweak your system to your liking then this is the unit to have. You won't be disappointed!

What I like
The ability to tweak to one's liking is awesome.

What I do not like
This unit is quite rare to find.
