Fujitsu Eclipse "Bottomless" Aluminum Subs and Q
My revelation was also with car audio. After graduating high school in 2002 I outfitted my 1991 Lincoln Town Car (that make and model won Motor Trend car of the year the year previous, but don't get a '91 because the it cheaps out on the secondary fuse box and uses insufferable fusable links instead, get a later year with the real second fuse box). Anyhow, I had 4,000 Watts of bass in the massive trunk. Previously, while still in high school and student body president I at one time transported 8 people in that car. 6 inside and 2 in the trunk. There might have even been a keg in there somewhere (Natural Ice Light, ha ha ha (incontrovertible kid beer))... Anyhow the trunk is huge on those cars.
I had 2 Japanese Fujitsu Aluminum Eclipse 12" and 2 American Kicker Comp 15" subwoofers with Rockford Fosgate Power series amps. I learned a few things setting all of this up. A few of them are don't use a lead acid battery in the trunk for your stereo (luckily we smelled it) it is hazardous in multiple ways, a capacitor makes the bass much better and keeps your lights from dimming and that $100+ set of RCA cables I splurged on at Circuit City with the twisting and the superior shielding and the marketing hype did nothing to alleviate the alternator/grounding wine I thought it would.
The revelation that sticks with me the most is that I bought a 3-way crossover from a local electronics store which had a remote. You know the ones on the wire with the knobs that you place under your dash somewhere within easy reach to turn the bass up and down. Well this one had a couple of extra knobs for "Q". I wasn't specifically looking for that but what it stands for I latter learned is "Quality Factor" and controls how wide of a frequency spectrum you are amplifying. So unlike an ordinary crossover I could choose a bass frequency and then basically direct ALL of my amplification, almost 500 legitimate Watts RMS according to the amps Rockford Fosgate Birth Certificate, into that single frequency alone by focusing the Q. Wow, my stereo bass was taken to a whole new level. My steering wheel would jump up and down vibrating by like several inches. I'm not sure how the steering column didn't snap.
I would love to find another crossover like that, or even just a jpeg of one to keep as a memento but I've been unsuccessful in my cursory searches...
