Wiring power cable from battery for amp

no thats not the grommet 

go up and a bit right.... there is a grommet (rubber) black on the bulkhead (on your photo you can just see it left to the coolant bottle - where the weld seem is).... the bit where you've poked in the probe tip is part of the body...

I did think it strange for a bolt to be called a grommet, but the grommet you told me about is much, much further up the body of the car than your own picture seems to show, which made me wonder if it was the right one or not - I'll go screw in the bolt again...

why not make a hole in the big one above where you put that probe in,thats where mine goes.

I marked it there because there is one TOO
Which is easier to get to (and comes out in an easier to access spot behind the tray under the glove box.

Thanks - I now have a nice 12.4v supply running the length of the car

I take it that is with the engine off mate as you should be getting a nice 14.4v when the engine is running.

Yes that was with the engine off, I wasn't starting the engine till I'd put the replacement alternator in. Did a test again today (before alt fitting) and its now 1.4v :-s

Edit: Had a bad earth, once the earth was connected a bit better to a temporary test location (the door stop) the amplifier worked perfectly.

Cheers lads.Just another quick question,ive run the cables for the front speakers down each side of the car under the interior sill trims,will I have any problems with interference from the power cable doing it this way?Could I wrap the power cable in something to stop interference?

Never had any problems myself and I have amped speaker feeds in the same location going to the front doors.

[boneybradley]

good quality cables help reduce interference... I used to sell some cheap crap that were 100% unshielded and caused all sorts of crackel n pop!!!

[Len]

Oh yes most definitely decent cables! For both the speakers and power.
