Sub + Amp install guide, done by a noob
This is my first time installing audio equipment into a car. Audio shop wanted to charge me 100$ for installation, so i spent a couple days watching youtube vidoes and researching how do do it myself.
These are just some tips on how I did it, I'm not a professional but have some electrical common sense.
For 12V+ A hole can easily be made in the rubber firewall grommet to pass the wire through, i used a round file for this
For 12V- I used the screw hole where the spare tire foam filler attaches to the chassis, scrapped the paint off and installed a nut and bolt with ring terminal holding the wire in place
I used a line output converter to get signal from rear speakers to the amp. Left rear speaker wire colors are (+)green and (-)green black stripe. Right rear Speaker (+) white wire (-)blue wire with black stripe. The quarter panels pop off easily and the insulation on the wiring to the rear door will need to be cut to access the speaker wires. I used T-tap connectors to pick up the speaker signals
For the "Remote on" for the amp, i'm running a wire from the (+) pin of the 12V socket, so that the amp turns on when the car turns on(its just a relay). I modified a 12V USB car charger to achieve this(opened it up, soldered wire to the positive pin)
I screwed the amp directly to the foam filler, seems sturdy enough.
The wires can be neatly tucked away under the panels or carpets or in the seat seams.
The boss LED subs are rated 800 watt RMS 1600 peak, and are relatively cheap compared to other 12 inch subs with the same specs. The blue LEDS are nice, I have them connected to a switch in the front so i can turn them on or off. Even when I leave them on the car battery (12v)doesn't die and the voltage stays above 12....Is the main battery is always keeping the 12v battery charged even when the car is off? Seems like it, but i could be wrong here
The sub box is sitting on the false cargo floor. In the pictures its tilted forward.
My volt meter has the voltage momentarily dropping below 10v when amp is turned up(max), i suspect this may be due to the 8 gauge wire. I plan on upgrading to 4 gauge soon and will post results.
