I'm looking at buying a pair of these JL 6.5" subs.
I already have a four channel that does 75wrms and that's what these are rated for, so it's just a matter of finding the right type of speaker for the job.
I have a set of focal comps for the front stage and a 12" type R. I feel like I am lacking some tight punchy bass. I notice it especially in rock songs. When I had the stock rear speakers in the rear doors where I plan to put the 6.5" subs, and even they added some punch that was missing.
Crutchfield says the max top mount depth for my rear doors is 2.525 and the JL's are 2 9/16 (equal to 2.6525). So I figure I'll be able to mod something to make it fit if I have to.
I just came here to ask for opinions, comments, and criticism on this idea. That's all it is at this point, so all ideas are welcome and will be contemplated!
