I remember Richard Clark and his project with Speakerworks....a Grand National....that was something! What a job it must have been fitting those horn loaded compression drivers in the dash.....and those subs with the mystical membrane!

 

So... Do I remove my cap and just leave it in one of the cup holders?

 

The SpeakerWorks GN had a large bank of capacitors in it before RC ever got ahold of it. They had basically nothing to do with what the "industry" came to sell them for. The caps in the GN were there to get rid of any voltage ripple coming from the alternator. Same concept as a power conditioner for sensitive electrical components plugged into the wall. They were mostly for the EQs and crossover in that car since they were modded professional units converted to run on 12V. As such their power supplies didn't have built in power filtering.

Clark and Navone began selling 1F caps around '90 as "stiffening caps". 99% marketing.

 

Update... actually, this setup in my truck is about 6 months old now, but I was enjoying it so much that I forgot to post. It didn't exactly turn out the way I said it was, though. No, there's not a MacBook in the truck.

Oddly, I don't have any pics of the finished product, guess I'll take those later. I used RAAMmat and Ensolite kit for deadening. I averaged about 40% coverage on the floor, back wall, doors, and roof, and it only made a slight difference in road noise. I used Masonite to seal the holes in the inner door skin, but I should've used sheet metal to better conform to the contours of the door.

The equipment in the first picture is what I got... all Alpine running off my old Wally World wiring kit. AVH-P4300DVD headunit. I have the 6.5's in the front doors, tweeters in A-pillar pods both running off the amp, and stock speakers in the rear off the HU.

I just shoved the sub under the center portion of the rear bench.

Overall, the system sounds fantastic. Nothing in the interior rattles. The tweeters are sweet, not harsh. Just super clean, loud highs. The midbass is nonexistent when played full range without a sub, which was a real disappointment. The crossovers took all the guesswork out of setup.

The sub is fantastic. It blends nicely and compliments the overall sound instead of overpowering it. My ported 10" in an Alpine-spec box was able to hit way lower, but it was all over the place. I'd rather have the tight, accurate bass of the SBR-S83V.

The PDX amp is sweet as well. The headlights don't dim, and I don't even think it gets warm unless I crank it way up. Still on factory ground wiring, too.

So, yea, I guess this is my "mature adult" basic system to get me through college.

Please don't judge my "amp rack" too harshly. Nobody looks under there anyways.




Now my 2 12's are gonna get lonely.
