Drilling a hole in the rubber just below where the a/c un off pipe sits is usually safe..20mm2 though? That's quite a heavy duty cable, is the alternator up to that level of drain? I've only an 8awg cable running an active fli sub and the car is much more rattly now than when I got it...

I have ran 0 AWG in my car but there is a hole already there to feed the wire. just remember wire it direct to the battery and don't use the fuse box beside the battery. also don't forget to beef up your earth cables as many forget to do this it.



when you push the cap make sure you catch in from under the car and make the hole in the middle and put some sealer round it and push it back on and you will be good.


heres my pictures:

I let the repair shop make a hole and draw the cable to the fusebox,I will connect it later.I will have my Signat amp under the passanger seat driven by my Kenwood head unit,in the front doors I have a Pioneer kit speaker and separate treble speakers.If everything works out fine I will have a box in the back with 2 coustic DR 10 inch woofers in Isobarik.

Is it okay to take the ground to the amp from the seatbelt bolt?
Are you placing the amp under a seat? Seatbelt bolt should be OK.
If in the trunk, there's a good ground point on the left side, 30-40 cm over the floor and fairly far forward (towards the rear seat-back, just loosen the textile/carpet.
