After six months of trying different options I have finally finished my install. From day one the sound was poor and the low end was very muddy. I still have more to do but this is phase 1. I was able to maximize trunk space short of mounting a sub on the rear deck (rattles). Currently I have a Zapco 500.1 amp on the driver's side. I made a little platform. The 500.1 has an internal fan so the enclosed area is great. The box is a custom made for a 10" and is around .70 cf. Here are some pictures.

Nice work. Did you tie in before or after the factory amp? Now with the trunk being sealed how much low end are you getting in the front of the car? You do not have a pass thru and that rear deck it sealed off pretty good.

Yes I had to tie in after the amp since it is all fiber going in. I just used a high quality LOC. I get plenty of low end. That is why I tried so many subs. Some were too much bass (Boomy) others were great (musical) but not enough output. Yes the trunk is very well sealed. I get a huge roll off around 125Hz but that is more from the factory crossovers. I am waiting on a new product that will fix all of the factory crossovers.

Ya good luck with Nick at Bassforms. You are better off getting it done yourself. I live in south OC and all of the shop owners have strong opinions about him. Their product looks great on a website.
