so most ppl just use the little bolt on the battery to give them a 12V source, and have a in line fuse. well....I have quite a few accessories: 2 sets (4 total) lights behind my grill, subs, police siren, e-cutouts, HIDs (soon to have some more). so my question is:

what can I do to still have a 12V power source but still be able to add all the electronic/power sucking "stuff" i want without having the engine compartment cluttered with wires?
