I like to bose sound system in my 8 but I want to go louder. I currently have a 10in JL Audio W7 with JL Audio 500/1 amp. I am getting a JL Audio 1000/1 amp. Now when it comes to the tweeters and the 6X9 rear speakers, I wanna know what brand sounds great? Any suggestion on a complete JL Audio system? Should I get another amp for the rear speakers and tweeters?
