Question about Sony Xplod (P589) Car Subwoofer
I have 2 12'' sony explode subwoofers with a alpine amp. in my car. i checked all of the wiring and everything is conected corectly and only 1 of the subwoofers is working. any solutions?
You need to remove the subs from the box in order to check the internal box wiring. First, make sure that the wire going from the nonworking sub terminals to the enclosure terminals is OK. Then check the "braided" leads on the back of the terminals going to the speaker cone. If the wiring all looks OK, remove the wires from the sub terminals, and use a multimeter set to the lowest ohm range and check the resistance across the subs terminals. You should read somewhere between 3-4 ohms. If the meter reads infinity (that is no reading at all), then the voice coil is open. If it "pegs" (reads "0"), the coil is shorted.
Either open or shorted means the voice coil is no longer working.
I could not find any replacement parts on Sony's support page, so it's most likely that they don't even repair these. They probably just replace the sub if it's under warranty, and if it's not under warranty, they probably recommend that you buy a new one.
Hope this helps.
