ok Im installing a set of Clarion components up front a st of Clarion coax in the rear a Clarion HU and a 4ch coustic amp. Later Ill add (1) 12 and a 2ch amp to run it. The components do not come with a crossover so what Im thinking is running the tweeters off the HU and the rest off the speackers off the amp. Is it a good idea to do it this way. This is going in a Hundai Santa Fe.
