When You Need Garage Tunes Right Now: Field Expedient Surround-Sound Audio System

When I moved into a Victorian near downtown Denver summer before last, I finally had something I've been longing for since I started messing around with cars: a garage! Since that time, I've been (very) gradually upgrading the place, with better wiring, insulation, beer signs, and so on. My long-term plan for the place involves an elaborate garage audio system, with a serious amp, good speakers all over the place, and a CAT5 line to the house that will provide access to the music collection on my file server. However, my long-term garage-upgrade plan also includes certain items that have higher priority— like, say, a source of heat— and I have been working on those items first. In the meantime, I needed to be able to listen to The Atomic Bitchwax at top volume, and I didn't want to spend any money on temporary measures. One afternoon, I scavenged up the gear to make an extremely loud four-speaker setup. Here's how. I had a pretty serious boombox already, in the form of the 92-pound Turbo II Junkyard Boogaloo Boombox that I built out of plywood and car parts a few years back (go to the Murilee's Greatest Hits page for the whole Junkyard Boogaloo Boombox saga). It had been just the thing for tailgate parties at Oakland A's games, but the battery I'd scavenged out of a junkyard-bound Tercel in 2006 had lost the ability to take a charge by the time I hauled it to Denver, and it would be an all-weekend thrash to dismantle the thing and replace the battery. Hmmm… how to solve that problem today? Easy— just add a battery charger to the crap sitting atop my pinball machine restoration project. The Junkyard Boogaloo Boombox charges via this PVC-pipe-based adapter that plugs into one of the cigarette lighters. The charging adapter was never meant to be used in a permanent setup, but it works. OK, so the battery charger leads clamp onto the charging adapter and the boombox now has Wanky the Safety Cat™ approval (provided I remember to unplug the battery charger when not in use). At that point, I had music… but the junkyard-correct Chevy Beretta cassette deck and '93 Mercury Grand Marquis 6x9s didn't deliver enough thump for my favorite Ice-T tracks. How can I improve the situation without leaving the garage? The cassette and 8-track players were hardwired in and it would be a supreme pain in the ass to add more amps and speakers to them, but the Junkyard Boogaloo Boombox features a wired FM modulator to allow the use of external sound sources through the cassette deck. That means I can use the same iPod I use for the LeMons Macho Man penalty… and it also means that the signal from the iPod can be split and fed into another means of amplification. From my days in the industro-noise band Murilee Arraiac, hooking up shortwave radios through chains of OD-1 overdrive pedals and so forth, I have every imaginable audio-cable adapter. Putting a one-into-two 1/8″ jack adapter on the iPod was easy, and led to… …this 900 MHz audio transmitter, which sends its signal to… …this pair of RCA wireless stereo speakers, which I got at a yard sale and had been storing with a lot of other random crap in a box for quite a while. Every bit of this gear was available right there in the garage. It's what the Murilee Martin Lifestyle Brand™ refers to as Ghetto Surround Sound 4.0™. I had to do a little rearranging of power outlets to feed everything, but it all sorted out in typical garage-octopus fashion. So now I can crank up the Gotan Project loud enough to share with the whole neighborhood, and I didn't have to buy anything.
