Hi, I have a 99 blazer 4x4 and im looking to start putting a system in the truck. Im in the process of looking to purchase a head unit for the truck. Im looking to spend around 250-300max or if you think I should save up to get a better unit, im looking for nice clean sound quality. I will be putting in 2 diamond 12" subs that my brother is going to give me also he has an amp not entirely sure what kind etc. Im just trying to find a nice head unit dual din or single whatever has better sound quality and will be good for 2 12" subs im also looking to get a nice component system. Thanks Much for your time and concern.
