Ripped out the JBL system on my Exploder - kept the speakers, including the woofer and purchased a Kenwood head unit, the CE202 amp and CX8 sub-w speaker from Boss. Ran the main speakers from the head and it sounded ok. Hooked up the CE202 to the CX8 and the sub from the JBL system - and wow - serious bass for a novice like me - for a great price I have a stereo that kicks. Maybe I got it down to 2 ohms like it says in the manual. I don't have speaker boxes made yet, so I cut holes in the boxes the speakers came in and ran holes for the speaker wire. lol.... works fine.
