Ok, so I had this crazy idea of taking out my glove box behind the rear passenger seat, and installing my 10'' JL Audio W3V2 to the already nice sounding (thanks to my head unit) Bose system. I figured their sub hit the mid bass pretty well and another sub that hits harder and lower would be even better I haven't really thought of a down side to this yet, but I am not a sound guru, so if anybody has any thoughts on my insanity I would appreciate them!!!! Man I love having my Z back!

 

no such thing as too much. lol there's a few members here that have done what you're looking at. they seem to be very satisifed with the outcome.
