OK I barely know anything about this Im just a girl trying to fix my system so I appreciate any help and apologize for lack of knowledge I can find out specifics of what I have if needed.
I have an 02 Mitsubishi Lancer that I bought off a kid who had a sub hook up already wired as well as a bunch of electrical things (I'm assuming he did himself) in the front like HID lights under the seats and an alarm system as well as a Pioneer deck he already had in. Got the car like 2 years ago, immediately hooked up my subs had no problem with that and everything worked fine up until recently. The alarm was set up with my remote start which broke so I had to put the alarm in valet mode so I could just use key entry again, in order to do this I had to mess with the wiring a little to find out which wires were the alarm, not sure what I did but I never worried about it again. A few months later (like 6mos ago) my subs would kinda just fall off, mid song theyd bump off to just regular bass, and then randomly turn back on. Wasnt really a pattern to this but eventually it fixed itself and my subs, deck, everything was working fine. But any time I had anyone look at my car they were like "wow whoever wired this did a terrible job"
A week ago, this AAA guy claimed he had to unhook my subs to get at my spare tire in my trunk which I reluctantly told him OK when he said he knew how to hook it all back up. Of course, since then my subs never worked and when I went back to check out the situation my wires were smoking and then my deck/electrical blew out (deck power, dash clock, ignition dinging, power lock). Had my friend look at everything, he ripped out a buncha wires from the HIDs etc that I didnt need and not sure what else but he got my deck & everything working again and then after puttin everything back it shorted out again. Had him go thru it all again, check my ground wires and deck harnesses, etc (not sure everything he did) and he had everythign working including my subs I was so excited and then mid song mid driving it shorted out again yesterday.
I bought new fuses I know there were 10As in there so I got 15As, not sure what fuse I should be looking for? Not sure which wires were smoking but they were in my trunk, could there have been damage and now its just gona keep shorting out? What else should I do?? I really dont wana bring it somewhere & get screwed, Sound FX already estimated me at like $250 just to diagnose it so I have a few people who know what theyre doing, I just would really appreciate extra help with the possibilities of what is happening...I wana sell the car anyways so if nothing else Id like to just get it back to basic without subs....HELP !!
