I would like to install my compact amp/subwoofer (Kenwood WOOX) in my new HCH II. I need to get access through the firewall to the 12v battery for a power source. I do not see an obvious (or easy) access, and would prefer not to cut into the harnesses that do pass through.

Any suggestions, or has anyone done this already?

I suggest you use the live 12V rail on the fuse panel.

You should have quite a few empty fuse sockets that will give you power without the need to snake through the firewall. Just make sure you amp is fused so as to keep things safe.

Second that. There are 3-4 switched and unswitched fuse positions available in the interior fuse block. All will handle 20 amps fine.

Thanks, great idea. I have put in an in-line fuse, so that should be covered.

If you're using the stock fuse block, do you need to order the proper termination connector to use the stock fuse?

The "Add a Circuit" fuse taps actually have a slot in them for the existing fuse, and a second position for a fuse to service the new circuit. In the photo, you can see that I have added 3 additional fused circuits to the car.

OE: I have two questions.
1. Where do you get those add-a-fuse things? I just have a wire going into the fuse box and an inline fuse later on.
3. What are all of those fuse taps for. (I'm trying to think of the mods you've done... maybe one is for the backup sensors?)

The Add a Circuit inline fuseholders are available at most auto parts stores.

The circuits that I have added to my HCHII are:

1. An ambient LED light to illuminate the center console. This is connected to the low-beam lighting circuit so it comes on only when the headlights are on.



2. An unswitched circuit for the illuminated door scuff plates



3. A switched circuit for the backup sensors

Thanks.

Can you point out which of the open spots are ignition-switched? I don't have my shop-manual (yet) and would like to use an empty one rather than piggy-back on a currently used circuit.

Thanks for the help so far!
