I have an 03 SC SE with a stock subwoofer system. My Question is what is the Ohms on it- I can't locate this info either on the speaker or the search function on this forum. I attempted to install my new JL 8 in Sub but I blew the amp fuse. My JL's are 4 ohms. I additionally combined the four wires on the stock sub [two hookups on either side] and connected to the new sub with only one location [two positives connected and two negative wires connected together. Is that correct?
