since you have a L, you can just swap that speaker with any aftermarket speaker. I would suggest getting at least a pair of 6x9s to replace both rears, because anytime you mix and match speakers, there's always are chance that the 2 speakers don't sound the same.tomas said:I recently noticed that 1 of my rear speakers was popping when the base hits. What do you recommend for replacing the rear speaker? I really don't want to upgrade my complete system to a new headunit, amp, etc. All I want is to keep the same setup but replace my rear speaker(s). Thanks for your input.
