i installed my type Rs today and they sound great. but what sounds even better is that i took out my rear 6 x 9s. so when my seat is up the bass enters the cabin through the rear speaker hole. you were't kidding about rear speakers. i just turn the gain up a little more on my amp to my 6.5components and it's perfect. i got two channels on my 4 channels just sitting there. also what do you think about adding another pair of tweeters in the front.
If u want u can sell the 4 and get a 2 channel. or just keep it (its not hurting anything), and if u want more highs go for it(remember its all about u like)
