thanks

I wouldnt recommend it if you havent done anything like this before but heres a basic writeup hope it helps.

Get a coat hanger pull it apart so its like a rod, get your powercable and tape it to the coathanger, open the glovebox fully so its hanging down off its hinges. Open the bonnet and look for a large black grommit on the passenger side with wires going into that is in line with the glovebox inside the car, push the coathanger through the gromit and wiggle it about until you can push it all the way in. Go inside the car and hopefully you will have a coathanger with a power cable taped to it sticking out of the glovebox opening. Pull it all the way through to the boot, tuck it in the gaps in the panels between the carpet and the panels.
Splice the blue control cable onto the blue wire on the head unit wiring harness, follow the same route ans the powercable to the back, tucking it into the carpet and panel gaps.
Get your RCA cables (red and white or red and black) and plug them into the headunit, run them to the back the same way as the power and remote cable but on the other side of the car eg drivers side for RCA, passenger side for power.
Ground cable connects to some bare metal in your boot (may need sanpaper and a spanner) I used the bolt used to hold the rear seat in place.
Connect the wires to the amp, Fit a fuse to the power cable somewhere near the battery in the engine bay, connect the other end of the power cable to the positive side of the battery carefully considering the route through the engine bay(cable tie it to other cables and follow the route of other cables to the battery)

I think thats it pretty much, you dont need to take any side panels off if your using 8 gauge wire as you can tuck them in the gaps with a bit of brute force...

cheers m8 very helpfull indeed ill let you know what happens

Fit a fuse to the power cable somewhere near the battery in the engine

I just skipped that important, got told it wasn't important and more of a style addition?

You skipped fitting the fuse? http://epcivic.com/f...tyle_emoticons/default/laugh.gif
Don't come crying here when you fry your amp when changing speakers...

its a alpine 2 channel amp 250watt only hooked upto the sub, cba with the speakers dont care about audio tbh, is it going to be all right with just the sub??

Without a fuse, if you're going to do anything to the amp you have to disconnect it from the battery. Better yet, the amp better be solidly attached to something if it's in the trunk. If anything (loose wire, forgotten screwdriver...) connects the power lead and the case of the amplifier it's bye bye precious amp. That's why the fuse is there, to blow if there isn't sufficient resistance. Saved my brother's amp when he did a little "maintenance".

im stuggling with the gromet bit its well hard to get off lol

You dont take the gromit off, you use the pointy end of the coathanger to 'punch' a hole into the rubber, anything else just ask....

You NEED a fuse, as said above, without one, if you drop the live on ANY metal in the car, it will get very hot very quickly. There is enough power in a car battery to weld 2 metals together, so it wont think much of setting fire to a piece of 8awg wire. Also, i wouldnt like trying to explain to an insurance company how i burnt down my car because i ran a live feed from a battery without a fuse.

Fuses are used to protect the wiring in a vehicle. Any large electronic equiptment usually comes with on board fuses to protect itself incase of overvolt/eccessive current draw.

ANY + CONNECTION FROM THE BATTERY NEEDS AT LEAST ONE FUSE!

A fuse is a good addition, saves blowing an amp etc..

BUT no its not 100% needed.. Just need to disconnect the battery before making any additional changes...

I've ran a sub setup without a Fuse, infact i did was an 8guage wiring kit and it was fine.. but when i stepped up to a 4guage wiring kit a Fuse came with it and i've used one ever since.

[RobbM]

Running without a fuse is blindingly stupid if you actually value your car and what it contains. Batteries can put out over 300A when shorted out, even small ones. 300A into a piece of wire rated to carry 40A just doesnt work. The power has to go somewhere, it turns into heat and burns untill the current no longer flows. Generally before that, a fire has already started and you have no carpets/seats/wiring/plastics left...

All to save £5 on a fuse and holder.

You know how a fuse works? Its just a thin piece of metal, when too much power has/is passing through it, it melts to stop current flow in a controlled fashion. When you have no fuse or one that is rated too high for the wire it is installed in there is nothing to stop current flow. Too much current = heat. A very basic welding set if you like


Edit, also a fuse in the wiring wont stop an amp blowing. Any decent amp will have internal fuses on the side of it http://epcivic.com/f...tyle_emoticons/default/wink.gif
