I am looking to add an amp for a footwell subwoofer. Where is the easiest and best place to pull power from? I really don't want to run a power lead back to the battery. If I have to do that I probably will scrap the whole idea.
TIA |

I have a couple pics of routing my amp wire on my build thread here:
http://www.914world.com/bbs2/index.php?s=&...t&p=2801031 I ran my 8 gauge wire right through the rubber snorkel alongside the factory harness. With the engine out of the car, it was a much easier operation to snake the wire than I expected. Took less than an hour total. I just taped a length of the wire along a stiff #9 wire to push it through and grab from the other side. BTW, I'm also running an 8" sub so installed a 4-channel by 75W@2ohms (50wx4 @ 4 ohms) to power a pair of Infinity Kappa speakers and the sub with 2 channels bridged. The amp I bought is listed as stable bridged at 2 ohms and not all that expensive either. |
