A little start to finish guide of todays work, with pics

and where is it?

chill out mate! lol. in an hour or so!

ok here we go... finding the grommet to get the wire into the bay:

pull your glovebox down and out, and you will see the huge rubber bung:



Pull back the sound deadening, you can see the wires going in... i found it too difficult to either peirce the rubber or to get my cable in with the other wires... im also very lazy... so i put the wire through in between the bung and the hole...



and up into the bay...



onto the battery like so...
remember to keep the fuse out of the casing, and to disconnect negative (-) terminal of the battery before attatching the cable

Now at the other end of the car...
i used one of the seatbelt mounts for the earth... removed the mount, sanded back the paint to expose the bodywork, putt in the earth, then put the mount back on...



put the box in etc etc... wire it all up, then put the fuse in, the reconnect your battery...

a view of my amp from inside the car... its attatched to the back of the woofer box.
the strap seen her is 1 of 2, used to stop the box sliding across the boot.
i fed them through the seatbelt mounts under the seats, then around the box. nice and secure as at first ithe box moved around, pulling out my remote lead

the trouble is that you have put the wire through the side the big grommet and the hole in the bulkhead it will chaff through and cause a short circuit
the other problem is that the amp power wire is very close to vehicle wiring, the electronic systems in cars are very sensitive and any wires like that pulling alot of current cause a large electromagnetic field which could cause faults in your car electrical system (error codes on the ecu)

installtion is pretty thick on that power cable tbh, unlikely to rub through to the bare wire any time in the next few years, and there is plenty of slack in it, so its not getting tugged at

also DC current doesnt get transmitted across to other wires like AC, so inteference will be minimal, especially as my amp isnt all that massive either

all it takes is a slight emf to intifere with digital signals to bring up a fault, i have seen this happen before. well suck it and see if you do get a problem you could coil some wire around the amp wiring at the bulkhead and earth it

well 12v DC straight off the batterys not gonna generate a field of any significance, if at all, so i think ill leave it as is...
