4th order bandpass design for 2 JL 8W7s

Recommended Posts

Anyone wanna take on the task of drawing up plans for a 4th order bandpass for 2 8w7s? Its going in a Mazda3 hatch with max dimensions being about 34 wide x 17 high x 17 deep. I would like the width and height to be maxed before making it too deep, so basically the shallower the better. Please PM me a cut sheet, I will Paypal you a gratuity in return. Tuning and size of box is totally up to the designer, I would like it to hit the lows well but also be musical.

Black 2008.5 Mazda 3s Touring 5 Speed Hatchback

Tinted tails/turn indicators, blacked out emblems, partially debadged, 20% tint all around,

Big 3 in Knu KLMX 1/0, LED footwells/interior lights

DECK: Kenwood DDX-512 double DIN touchscreen with backup camera

FRONT STAGE: Stock for now, yippy (Looking for something nice...)

FRONT STAGE AMP: Looking for something nice...

SUB: 15 inch DC level 4 with level 5 coil upgrade, red dustcap

SUB AMP: Audiopipe AP15001D at 1 ohm

WIRING: All Knukoncepts Kolossus/KCA wire

LEGAL TERMLAB SCORE: 135.8db at 42hz(pathetic, I know. I need a battery in the back,

dropping to 11.9v isnt cutting it.....)

I haz teh Term-Lab. PM me if you are close and want to get metered.
