just wondering were all you put your power wire from the battery to your amp though the firewall?
I took a look and couldn't find a place. it's a 95 integra

Thanks

check right beside the battery you'll see a grommet, you can fit a power cable through there.
cheers good luck.

that grommet is pretty tight...try using the other grommet on the driver side of the firewall...and a whole lot easier to fish out from inside the cabin as well
