Well Figured I would add my Build log here. I have changed it several times over the last year and am now happy with the outcome, well for now. LOL

ARP head studs, EGR delete, Oil cooler, Full 4in Exhaust, Innovative custom tuning, Suncoast Billet race trans and converter.

The goal here is to be very loud, low and sound good doing it. I'm hoping for 154's but want to do it peaking low, I would like 152's+ around 30hz, but main goal is to sound good, this will not be a burp box but built for demos.

Time to seal it off and make beauty panels

sorry for the shitty photo

wall1_zps1ac86df5.jpg

I made the panels extend to the B-pillar. Not sure if this helped but its nasty on the low notes and moves a ton of air for one amp.

I will still add sme leather accents to the face of the wall. But im in no rush now.

It sounds amazing and is loud as piss. Not sure what it will meter but the goal was 152's on music and doing it low. Remember this isnt built for numbers but to be loud to the ear. My last 150 setup sounded louder than some 154 setups I sat in...... honestly. I dont know it may meter way higher than I am thinking. Its hard to breathe sitting in it sometimes.

here are a couple vids before it was sealed off. Its louder and lower sealed off. I will get new videos and some hair tricks on vid soon.
