Hey all, how did you get your amp power cable from your battery to your amp? Is there a hole in the firewall somewhere? Cheers;.

If your car is an auto then there will be a hole a bit below your brake booster.

best bet is to look around the engine bay for any holes or rubber plugs that go throught to the dash. can't quite remember where mine goes through, but pretty sure theres a rubber grommet near the brake booster, where you can just push the cable through, then hunt for it on the inside!

yep, thats where it is, i never found mine quick enough though, i ended up drilling a new hole to the left of the pedals, my power cable runs along the metal frame of the car then goes up near the battery

Manual or auto. You will have a small gromet near the brake booster... If you dont have enough room to get the wire through, just cut into the grommet. Dont take it out. Also make sure you are running your RCA cables on the opposite side of the car to the power wire!

You run the power cable and the rcas on different sides of the car to make sure there is no interfearance in the sound.

very true, but it is cafe to run remote/turn on wire with the rca's, thats the one to the headunit that turns the amp on and off Some original photos have not been recovered yet.

Yeah you can run the remote turn on with the rcs's as these are very low current and are really only a signal wire. Some rcs's even have them as part of the lead.

Yes. having the RCA cables running down the same side as the power cable you fill find they will interfere with each other. Causing a buzzing sound through your stereo. You will really notice it while revving through gears.

But if you've got half decent rca's and power with decent insulation it'll be fine.

um... i think then most poeple dont have half decent insulation, it's just easier to run them down different sides anyway. i ran my rca's down the left side, under the carpet to the left then under the plastic door sills and the cover for the front seatbelts, but you could also put them down the middle if you have a good enough reason to, it'll take shorter rca's that way

i actually found my amp wire from my deck didnt seem to work properly and i ended up getting a flat battery when the amp stayed on while the car was off.. to safeguard agains this, i always wire the amp remote wire in with the accessory power now..

You will really notice it while revving through gears. ths would of been good information 2 months ago i bought those earth inhibiters that connect to the rca's then go to the amp but there not cheap it fixed the noise that was driveing me crazy, when the road was wet it would get even louder, but with the older head unit it was fine only when i put the sony in it started
