I have an 05 wrangler X and the factory sub has gone out 4 times now, I had it replaced 3 times by the dealership but it takes them nearly six hours to do it and it blows within a couple weeks. I went to buy an aftermarket and just install it myself, took the subwoofer out and took it to two audio specialists in town and they both told me it is a 2 ohm dual voice coil 6.5 inch woofer and I can only get the same one from Jeep...first can I get it somewhere else? And second if I have to get a single voice coil how much worse will that sound??
