I bought a second hand system from a friend. Worked great in my explorer until last night when driving home. The subs quit playing.
Specs: One 10" RF punch P3 dual voice coil 4 ohm. The amp is a sony xm-zr604. It is a 4/3 channel amp. The amp is 150x4 at 2 ohm and 300x1 at 4 ohm. Wired with a new 8 gauge memphis wiring kit with monster 14 gauge speaker wire.
The problem is the bass comes on intermittently for 10 seconds or so every twenty minutes. I can adjust the volume the whole ten seconds and it does not effect it. The amp light is green when the subs are not working. The ground is good (under back seat where the seat bolts to body, grinded washer and body down to bare metal and used a proper connector). No fuses are blown at amp or at battery.
I had not taken the sub out of the box yet. I figured it was the dual voice coil 2 ohm version wired in parallel because the amp was bridged to 4 ohm then wired to the box. After taking the cover off the amp and seeing no sighns of a burned out amp I took the sub out of the box. It was wired to only ONE voice coil with what looked like 20 gauge wire that was halfway connected to female connectors. Found out the sub was dvc 4 ohm. Wired it with 14 gauge in parallel at 2 ohm and hooked it up to the bridged amp making the amp 4 ohm. Still no movement from the sub so I hooked it up unbridged to the amp which should have been feeding 150 watts at 2 ohms to that channel with the sub hooked up at 2 ohms. Still no movement of sub.
Sorry for the long post, im completely stumped. Any ideas? Amp nor sub smelled burned. It also hit suprisingly good for a ten hooked up the way it was the first two months.
