Several half-assed/backseat installs (left, circa 2004-2006) later and I figure I'm ready to start something that will look good (for once) while sounding like I have King Kongs in the trunk of my e39.
Caveats: Be careful when you mess around in the trunk/under the hood. If you're ever unsure, leave it to the pros - that's what they're there for. Always disconnect the battery ground cable before making any new power connections. Your car battery stores enough power to melt your belt buckle and the change in your pockets and liquefy your eyeballs and the fillings in your teeth. Respect it.First is the prep and wiring: (1) Gut your trunk. Tap into your factory speaker wiring using a line out converter so you can keep your stock deck; tap a radio antenna wire and use that as your remote turn-on lead. Anticipate (more than) a little rattling and vibration and apply sound deadening - I used some leftover eDead and matted the rear speaker shelf. People that use power cables smaller than the ones I use to wire my speakers are trying to enjoy a delectable boba drink through a regular straw. (2) I ran 1/0 awg wire from the battery (fused within 6in. of the positive terminal) and distributed 4 awg to my amps. (3) If power cables are like veins within a persons body, then my trunk is a bloody mess. Turning the key in the ignition I swear I felt like a Witch Doctor Frankenstein and heard Igor's voice whisper in my ear: (4) it's alive.
