[Vtec_Power]

Ok this is to Install a head unit, 2 Subwoofers and an amplifier in a 1992 civic 4door, Its off the top of my head and i'll put pics in later.

What you will need:
1 Head unit with amp pre-outs (pretty commonplace these days, unless you hit up wal-mart and get a Rampage tape deck....)
1 Wiring harness made for a honda civic.
1 roll electrical tape
1 pair wire cutters
1 pair wire strippers
1 Amplifier preferrably 2 channel
2 Subwoofer(s) installed in a box, ported, sealed, bandpass, whatever.
8 Gauge Amp Install Wiring Kit you can find this on ebay for 20.00, DO NOT GO TO BEST BUY AND BUY THE SAME THING FOR 120.00!!
misc. tools, zip ties, etc.






First off you want to disconnect your positive battery terminal, lord knows what electrical problems you will cause if you leave that thing on there and mess with the electricals.

Now, first off starting with the head unit. You are going to want to wire the wiring harness first. The red black and yellow wires are going to be the longest, leave those for last, now

1. Take the harness that came out of the head unit box and lay it out, make sure you notice the stripes and stuff, you dont want to cross wires, being careful and patient here will pay off.

2. Start stripping the ends of each wire, generally i strip about 1 inch off the ends to give me room to play with.

3. Take the wireing harness you bought for the civic, do the same as above, As far as i can remember they should come pre-stripped, you just gotta pull the ends off to expose the wire.

4. Now, all of the wires should be stripped (except for black, yellow, and red).



5. This is where you start twisting the wires together, take one wire from the head unit wire harness, and match it to the wire from the wiring harness you bought, take the ends and twist a good 4-5 times. Use your judgement here, just make sure the connection is tight.

(See the Diagram Below to see how you are to fold the twisted wires and then tape them together to ensure that they dont come apart)


Once you have finished wiring all the colors that match, take the remaining 3 and just tape them off at the end, they arent going to be used.

7. Now move on to the black yellow and red wires, and connect them together, only AFTER you have measured them to make sure you have the correct length to move around with, LEAVE THE RED WIRE UNMODIFIED FOR NOW, (trust me, you'll see why.)

8. There are 4 screws you have to remove before you can get your head unit in.

9. Right under the stereo there are 2 screws, remove those, place the left one ont he floor on the left, place the right one on the floor on the right.

10. On the bottom of that column there are 2 smal screws on the left and right that you must remove.
(people with the auto perform step 11).

11. Place keys in ignition, and move it to ACC, if you forget and turn it all the way and your car turns on, stop and disconnect your battery..Then Press the brake and place the car in 1, make sure the ebrake is on and working.

12. Now, pry off that bottom plastic piece and move it aside, be careful because the cigarette lighter is connected to that plastic piece, you dont wanna rip that off..

13. Now you can get to your stock head unit, there should be one screw at the back of the head unit that is holding it in place, unscrew that and voila!, slowly pull the stock head unit forward, move it enough to get your hand back there and unplug the antenna and the factory head unit harness.

14. Yank that underpowered, crapbox you want to call a "stereo" and put it somewhere, who knows when you sell your car you might want to reverse this process and replace the stock stereo one day, anyways. Now you are ready to start installing your head unit.

15. Take the metal sleeve that comes on the new head unit and slide it off. Use a knife or a flat ege or something and be careful.

16. Put the sleeve in the DIN sized slot in the dash, now there should be triangular tabs of metal on the sleeve, bend those as best you can behind the lip on the dash opening. (to prevent theft.)

17. at this pont, the 2 wiring harnesses should be attached together sans the red wire, (yes still, trust me be patient).

18. Now, open the amp wiring kit and take the RCA cable out, plug in the RCA cables into the back of the head unit at thi point along with the head unit end of the wiring harness.

19. Run the RCA cable into the dash opening and towards the drivers side of the car. then slide the head unit into the dash a little bit just in reach of the antenna cable and the factory head unit, now attach the white end of the harness to the factory end of the harness, and attach the antenna. once you are POSITIVE that they are in all the way, push the head unit with the 4 corners (not the middle) until the stereo clicks into the sleeve.



20. You are now done installing the head unit. Now onto the amp.
