I have a used box built by AutoToys here in Randolph loaded with dual 10" Boston Acoustic G110 subs (if I remember correctly, they are series wired).
Fits PERFECTLY in the back of a TJ.
Solid construction although the carpet is a little worn and could use a little spray adhesive in some spots
I powered it with a 500 watt JL amp; sound was tight, full and clean, but is not that overpowering, earth-shattering, wake the neighbors kind of bass...
Sold my Jeep, so now I have no need for this box.
I still have the amp as well, but will consider selling it...
I will not ship this, so you either have to pick it up or we can meet somewhere within 20 miles of 02368.
Please call or email if interested... ****if emailing: MUST include a phone number otherwise it will be IGNORED****
