I just traded my stroker for a new yellowtop, so I figured it's time for me to make another install. I decided to make a 4th order cut through running one 15" opti1532d. My main reason for running lanzar is because everyone I know thinks it's trash. I guess "trash" comes with a 4 inch voicecoil and 19mm xmax. I would of cut through my rear deck, but I'm not really experienced enough to keep that setup mobile in case I needed my spare tire. I cut through my rear seat, I believe I lost output compared to the deck, but this eliminated any rattling on the interior and exterior. I've already metered her, the loudest frequency is 32 hz and she does a 140.8. on the dash and a 158.5 in the port. There is a lot of air coming out the port, you can feel it in the front seats.

I didn't mean to make it peak @ 32, I was aiming for mid 30's but my newb ass got sub displacement in my ported chamber wrong. Anyway, here's the pics......

... interesting

Looks nice!! I am thinking about doing the same type of porting, coming through the back seat arm rest. But i am just doing a regular type box.

Looks good Brother! Sounds like it gets nice and loud!!! Thats a pretty fancy box the sub came too.

I like it, That's thinking inside the box
