Hi guys, new S15 owner here in Okinawa. I've also never posted in a forum before so please don't rip me a new one as I am still learning how to navigate the page. I wanted to change out my door speakers to a coaxial set-up so I didn't have any tweeters sticking out of the door cards. I installed the speaker (rocksford fosgate 6 inchers) on the driver side using the original terminals/wires and tested it before I put everything back together. it worked at first but then stopped working soon after. I got home and cut the wires and replaced the terminal connectors. still nothing with the speaker. When I go to start my car, I get no response outside of pure electrical. All my dash lights and overhead lights work. Headunit works as well, but nothing with the engine. I replaced the battery and still nothing. I am not savvy on fuses or relays or what not, but I pulled all fuses from engine bay and under the dash and everything looked fine. Any Idea on why this may be happening?
