hey everyone i havent posted in a while. since my car is being fixed right now, until it is finished im driving my dads 95 lexus es 300. i wanted to connect the system i have in my car now to it but i have no idea how. some of the info, its a rockford fosgate 800a4 amp with 3 JL audio 12" W6 subs in a custom box. it POUNDS!!! anyway, i was hoping someone would be able to give me directions for connecting it. im very handy and have some technical backround, and im pretty good with figuring things out. i went to my audio guy and he told me to come back after christmas and that i might need some type of connecter but i cant wait, but at the same time i know i dont wanna screw it up. the jobs gonna cost me $130, which isnt bad but still. HELP!!!!


(extra info- i have the factory dash and want to keep the current factory speakers as well. i hear this includes splicing of wires? help!)

how long will you be driving your dads car? hooking up a subwoofer and amp is not a 10 minute job. these are the steps you'll have to follow:

1. connect your amp to your headunits RCAs
1a. if there are no rcas, tap into your speakers with a line level adapter
2. wire the car for power, this involves running 12v+ power wire fromthe battery to your trunk, grounding the wire, fusing, etc
3. putting your subs in, mouting them so things dont fly around

that's it...might not look like a lot...but it's not a fun task to do when you'll be getting your car backanways

Yeah your definately looking at time. First step will be running your power cord from the + batt to the amp then your ground to the car. Your amp and speaker wiring and box I assume is already hooked up so you can just throw that on in. Im guessing this will be a temporary setup since your dad's lexus is using the stock headunit. There are two ways to do this. Your amp needs a signal from the headunit so your subs can put it to use. 1) They have these adapters that connect to the rear of the facotry headunit but then you have to wire from there all the way to your trunk. 2) If you have a electronic xover i would probably go this way. The system will prolly be in your trunk and the xover should have a adapter that plugs in the side with several wires depending on the channel xover. Take the channel you wanna use + & - with some speaker wire and since youll prolly be in the trunk you will have easy access to the factory rear speakers. All you will need to do is slice into them a lil and get some bare wire and join the wires. Then after you get that signal your good to go but I gotta tell you temporary setups like this dont sound as good as a quality job.
