hi guys i need some help with wiring my amp up in my mk1 focus

im wondering if there is an easy way to get a 10g amplifier power lead from the battery into the car without drilling. ive looked everywhere and cannot find anywhere i can push the cable through. ive searched the forums but cant see anything of help

i hope someone can help me. pics would be even better

thanks

[size=4][b][i]There MUST be a grommet somewhere under the bonnet, where the wiring loom goes from the engine bay-into the car. Usually behind the battery somewhere. Just slice a big enough gap to get your wire through.[/i][/b][/size]

cant seem to find it anywhere. it was easier to do in my mondeo but this is a pig to do lol
