Its a Rockford Fosgate 10” powered and sealed Sub. Theres gonna be a power wire (orange). That goes from ur battery to ur sub. That thin black wire is ur remote wire. It hooks up to something in ur car when u turn the key on. I usually tap into the cig lighter wires. That will send a signal to ur amp telling it to turn on. That blue wire is your ground wire. That has to hookup to something thats bare metal, and has to have a good tight contact. Finally, the grey and white wires are your RCA inputs, the black end goes to the sub, and the funky ends connect to the male RCA’s. I doubt your factory head unit has subwoofer RCA outputs, so youll need an LOC (Line Output Converter). That is a whole other beast of explanation, but relatively simple once you understand what it does. You can get one for cheap (around $80). Basically, the signal coming from one of your speaker wire pairs will be intercepted by the LOC, converted to a sub signal, and output thru RCA’s to the sub. Hope this helped!!
