When i first started looking for a new head unit i thought about goin with Kenwood because i have four Kenwood speakers already but id been hearing some good things about sony so i considered it. Now Pioneer seems to be something that lots have recommended and i will be looking into them a little more. I will keep alpine in mind as well. Havent had alot of time lately so i havent had a lot of time to research. Thanks for all the input!
