THIS IS MY 2000 VW GTI GLX VR6 A.K.A. "FIRE". THIS IS A PICTURE OF THE FINAL PRODUCT FOR 2 12" SUB WOOFERS IN A BANDPASS ENCLOSURE. THE BOX ALONE IS 5.7 CUBIC FEET! MY BIGGEST CONCERN WAS I WANTED IT TO LOOK VERY STEALTH, BUT HAVE ENOUGH UMPH TO BLOW AWAY THE COMPETITION....... SEE THE BIG RED CIRCLE IN THE MIDDLE? THAT'S THE 8" PORT FOR THE BANDPASS..... BOY IS IT A MONSTER! THE 19" WHEELS DO THIS CAR JUSTICE.

IN THE BEGINNING, THIS IS WHAT WE HAD TO WORK WITH..... BUT I WAS STILL UNDECIDED ON WHETHER I WANTED A SEALED, PORTED, OR BANDPASS ENCLOSURE. IN THE PAST I'VE HAD NUMEROUS SEALED AND PORTED TYPE BOXXES, SO NOW I WAS WILLING TO EXPERIMENT WITH BANDPASS

1ST WE BUILT A TEMPORARY ENCLOSURE TO SEE IF IN FACT THIS WAS THE SOUND THAT I WANTED FROM MY NEW 12" ROCKFORD FOSGATE HX2's. THIS WAS IN FACT THE BIGGEST BOX I'VE EVER SEEN FOR ONLY A PAIR OF 12'S. BUT IT WAS ALSO BY FAR, THE MOST EFFICIENT SOUND I'VE EVER HEARD.

IT WAS TEST FITTED IN THE TRUNK AND I WAS MORE THAN HAPPY. NOW MY NEW CONCERN WAS WHAT I HAD LEFT AS FOR A TRUNK. BUT AFTER SOME CALCULATIONS FROM THE VOODOO MAN, WE DECIDED THAT WE COULD FIT THAT MONSTER INTO MY HATCHBACK AND STILL HAVE ROOM FOR GROCERIES AND OR SMALL LUGGAGE. THE TERMINALS WERE ALSO PROTECTED.

SO THEN BEGAN THE PERMANENT INSTALLATION OF A CUSTOM ENCLOSURE.

1ST THE CARPETS, SPARE TIRE, JACK, ETC. WERE REMOVED. THE WHOLE REAR END OF THE EXTERIOR WAS TAPED TO PROTECT THE PAINT. MORE MEASUREMENTS WERE TAKEN. POPCORN WAS USED TO MEASURE THE SPACE WITH-IN THE SPARE TIRE WELL(2.7 CF USED FOR PORTED PORTION OF BOX).
AFTER THAT WE LAYED FIBER GLASS AND RESIN TO CUTOM MOLD THE WELL.

WHILE THAT WAS CURING, WE CUT AND PRIMERED ALL THE PIECES FOR THE SEALED PORTION OF THE ENCLOSURE.
THEN 3 COATS OF "OEM VW RED" WERE APPLIED AND LEFT TO DRY.

ASSEMBLY OF SEALED BOX AND ASSEMBLY OF PORTED PORTIONS WERE MATED TOGETHER WITH BONDO, "A PEFECT FIT", WHEW!!!

THEN FITTING IT INTO REAR OF VEHICLE WAS ANOTHER TRICK. ORIGINALLY WE INSTALLED THE ROCKFORD FOSGATE 500A2 AND 500A4 AMPLIFIERS. BUT AFTER A TEST RUN, I DECIDED THAT I WANTED MORE. SO WHILE THE PLEXI-GLASS WAS BEING CUT WE UPGRADED THE AMPLIFIERS TO THE 800A2 (FOR SUBS) AND A 800A4 (FOR COMPONENTS).

AS YOU CAN SEE EVERYTHING IS COMING TOGETHER JUST FINE :)
THE FRENCH COVER ITSELF WAS VERY TIME CUSUMING, SINCE IT HAD TO FIT PERFECTLY! PUTTING IT IN THE CAR AND USING BONDO TO FILL IN ALL THE LITTLE CRACKS AND CREVICES. ONLY THEN WERE WE READY TO SPRAY ON THE GLUE FOR THE MATCHING CARPET TO BE CUT PERFECTLY AGAIN! THEN THE NEON LIGHTS WERE THE FINISHING TOUCHES. BUT EVEN WHILE THE NEON LIGHTS WERE BEING INSTALLED, WE WENT AHEAD AND SAND BLASTED THE PLEXI-GLASS WITH AN 8" TALL ROCKFORD FOSGSATE LOGO.

AFTER ALL WAS SAID AND DONE FOR THIS PROJECT, WE USED A SPL METER AND A OLD 1995 IASCA CD. OUR HIGHEST READING WAS 147.8. WHICH IS A PROUD ACCOMPLISHMENT FOR ONLY 2 12" :)
ON 4-20-01 U.S.A.C. WAS IN TOWN FOR A LITTLE SPL/DB5/PORT WARS. AND OF COURSE I WAS THERE AND ENTERED MY 1ST EVER COMPETITION. I WAS ABOUT 35TH IN A LINE OF CARS OF ABOUT 45. THE HIGHEST DB FOR THE NIGHT SO FAR WAS 144.2 FOR THE STOCK 601+ WATT CLASS. WHEN IT WAS MY TURN I USED THE NEW U.S.A.C. CD (TRACK 19) AND BLEW BY WITH A 146.3DB. I WAS REALLY HAPPY. THEN AS THE NIGHT WENT ON 2 PEOPLE PASSED ME IN MY WATT CLASS AND I ENDED UP GETTING 3RD PLACE FOR THE EVENT. BUT I THINK I AM SATISFIED WITH MY SPL PERFORMANCE AND WILL CONCENTRATE MORE ON SOUND QUALITY FOR FUTURE EVENTS. ANOTHER THING IS THAT I NEED TO SEE WHAT FREQ. MY BOX/CAR IS TUNED TO SO THAT I CAN ENTER IN FUTURE PORT WARS.....
