I wont be able to fit my subs in my new build and was wondering what size and how many subs to run. Subs will be going in an 07 chevy tahoe behind the second row seats in a 4th order wall. I currently have 4 Incriminator Audio Death Penalty 18's and need to down grade in woofer size.

I want to get 4 15's

Should I get 4 of these?

If you guys have any other suggestions, please let me know. Thanks

Ok, I've been pondering this idea for a while now. I just got an 07 black chevy tahoe. I took out the 3rd row seats to make some room for a new setup. My question is this: Do you guys think I'll be able to fit a 3rd row 4th order wall in the back. Or should I just go with the traditional ported wall? I want to run at least 14 14v batteries (12 in the rear and 2 up front). I still havent decided if I want to keep my 4 18" death penalties or get 6 15" wardens (8 if they will fit). Has anyone done this yet in the 07+ style tahoes? Also, I've seen a few youtubers do this and I got the idea from them. I want to run 14v batteries for daily usage. Or should I just run 16v batteries and keep the vehicle on 12v? They seem to love the 14v setup and I would like to try it too, has anyone done this yet on the 07+ tahoes?
