I sold my 4 10"s Kickers. I found this deal on craigslist I couldn't pass up.
Lady was selling the subs and 2200 Watt amp for 450$. So I bought them and went home and got them installed ASAP.

My back window:


Subs Before I put them in:


Subs after I put them in:


Amp installed and under box:

That power wire looks a lil small for 2 15's

I could never put 15s behind my seat. Not that I don't want to, but I can just barley get my seat back far enough (the last notch) with 12s as it is. I do want to eventually switch out Hifonics for Kickers though.

Actually it doesn't take up that much room. I have the box all the way against my back wall and I can put my seats way back and recline them. I'm 6"1 I'm very happy with them and they sound amazing and the bass is real deep. I plan on buying this real soon!

After taking a second look at your pic with the box behind the seat: The box sits about 6" lower below the back window than mine. Might be why you can recline the seat. I am 6'5" and that is NOT happening for me. Although, the seat reclines back to where I like it...but just. I am happy I can get the seat to the back notch at least.
