Meghan has wanted a little something to fill in the missing low end in her Mazda so finially got on it during the last 2 weeks

Box is quite small as we didnt want to take up much room, eventually I plan to make fiberglass enclosures in the side panels but this will do for now.

Box Is 2.53 Cuft before disp. 2.17 after port and probably right at 2.0 after sub and port disp

Port is 30Sqin by 18.75 in long

After all is said and done threw it on the meter and it does a 138.9 on the dash with 140 watts clamped LOL Not getting much actual power off the JL at 4 ohm, but its good enough for now

I think the JL slash amps are only 1.5 ohm stable. Im sure it would run as I think these coils are 4.1 so would get me right at 1.xxxx but Im really not worried about it.

If I wanted power I have a Kicker ZR600 that we could run and I know that amp has been clamped at over 600 on some setups but im really not that worried about it.

Would love to take it to a MWSPL show and look at the puzzled looks hen it only clamps 140 watts LOL
