Plans to go for a drive in my 914 this weekend were dashed by yesterday's stay-at-home alert, so I finally dug into a minor project I've been putting off: Rebuilding the car's 28-year-old audio system. While it performed well for 15-20 years, a mixture of age, heat, moisture, etc eventually caught up to it.
System goals: 1) Install a system powerful enough to be enjoyed with the top on or off; 2) maintain/improve "period correct" appearance with no head unit and, if possible, no visible speakers; 3) minimize weight; 4) avoid or minimize additional holes/etc. I'm going into this with the understanding that it's entirely possible the exercise will be futile with a 2.2-liter flat six, but I have been collecting the parts over time and figure it's worth a shot. Some of this stuff has been sitting for years and thus may not be available anymore—but plenty of alternatives are. Old system components: Pyle graphic EQ turned on/off by factory rear defrost switch Pioneer fan-cooled amplifier (~1991) Boston Acoustics four-speaker set in doors (~1991) Pioneer ducted bass wedge in passenger footwell New system components: Smartphone with a proper mount > EQ Blaupunkt five-channel parametric EQ JL five-channel amplifier JL six-speaker set for factory speaker enclosures and door ?? subwoofer in passenger footwell (prepare for now, add later) Fair warning: This thread may proceed at a glacial pace, as midlife plus a small business means my days in the garage are fairly rare in this chapter. I'm also figuring this out as I go, and will use this thread as a journal and a place to share ideas. |

With the speaker enclosure plan coming into view, it's time to deal with the dash next—which brought me to the time-honored "while you're in there…"
I replaced my head unit with a smart phone about a decade ago and never looked back, replacing it with three gauges canted toward the driver. With no need for a clock, and no desire to install the amp and crossovers behind/under the dash only to have to remove them, I finally decided to order an outside temperature gauge—and will be sending it to North Hollywood Speedometer for a silver dot and (hopefully) a vintage bezel and glass.
