I had a UsAcoustics USX-2080 amp (280 watts bridged-claimed) from my old boat, so I decided to use it to drive another JBL 8 inch sub. My plan was to remove the back seat and replace the stock driver with the JBL, put some stuffing material in the box, run the subwoofer leads to a speaker level to rca level converter, to the amp under the front passenger seat then the speaker leads back under the carpet to the sub. I had to cut out the plastic screen on the woofer's box because the JBL was about an inch and half deeper. So after grounding the system and running a test lead/remote lead from the battery, I found out the JBL was damaged, suck! So, I put the stock sub back in with the JBL's metal screen on the outside of the box for protection and ran the wiring the right way. I wired the remote to one of the 12 volt outlets in dash and ran the battery lead through a firewall grommet to the amp. So it was time to fire it and to my surprise, even with the lack luster stock sub, the output was drastically better. It can now push a lot more air, though it will start to bottom out way before the bridged amp reaches its limits. The sub also seems a lot less mid-bass heavy though it still can't go very low, I'm assuming it starts to drop off pretty quickly below 40hz. So, if you have a spare amp laying around you may want to wire it up. With just a simple modification or two, you make your stock sub sound much better. I have a ten inch Reference Bazooka tube that'll I'll try, just for fun. I'm sure it will dominate the stock sub, but I don't want to lose the back seat just for more bass. Thoughts?
