I bought my Versa last year because I needed something good on gas and reliable but I didn’t want to spend very much money so I googled “what’s the cheapest brand new car” and boom I got my Versa the next day. Only problem is I really enjoy my music and the audio system was just no doing it for me so I decided to completely overhaul it. My three goals were to keep it looking like stock, be able to return to to 100% factory, and obviously have a good sounding system. So i got two harnesses (to the radio and to the car) and soldered all the common wires together and then ran speaker wires from the radio harness to the amps (under driver seat) and put speaker level to RCA adapters on the other end. Then I ran 4 gauge from the engine and followed the hood release where there was a grommet I could pop out and put a different one in for the wire to run through. Ran the wire to a distribution block there I tapered down to 8 gauge for the amps. Then from the 4 channel amp I ran 16 gauge through the boots to all the speakers where I built speaker rings out of MDF. From the mono amp I ran 12 gauge to the trunk for the 2 6.5 inch subwoofers sitting in a 1.23 cf ported box. All wiring used was OFC from Sky High Car Audio and all amps speakers and subs are Toro Tech Audio. Hopefully all enjoyed hearing about my experience a little and if you have any questions or any tips I’d love to here them. Thanks!
