2. 12" Double Subbox Sealed
Again in perfect conditon, It's basically 2 boxes joined together so even If your using one subwoofer, It'll work perfectly as each sub has it's own enclosure!

3. JBL GT4-12 Subwoofer
Dont let the price put you off, The subwoofer really is very good considering the price. This one in perfect condition/working order

4. JBL GT4-12 Subwoofer (Damaged)
Same as above but the subwoofer cone is wripped, still works perfectly though. Easy fix for someone who knows about fixing speakers.
All of this above will cost you £200+. I'm selling it for £90 or near offer. Thats the price of the amp on its own. You can use the one subwoofer and it'll still work perfectly until you get the second fixed/replaced.
Payment has to be cash on collection as all of this is too heavy to post!
