I am looking for little tips to get louder? Just little things or maybe even simi big things to improve my numbers. Right now I only have two things on my list. My uncle suggested rounding off the bottom of my port, and resining the full inside of my box. I was also wondering if using 1/4 wood to make my full trunk into a box would make it louder? right now alot of sound is coming threw my backseat and back deck. But I have two 6" ports into the trunk, so making the trunk into a box would be making it into a 6th order bandpass box. Would it be louder like that? or would I get bigger numbers just letting all the sound come in anywhere it can? Thanks in advance

Sealing the sides of your trunk will only help if you completely seal off the space behind the boards... like with foam or many layers of wood. Cavities of dead air will only bring your score down.
For trunk cars, you have to find the right box size, placement, and port/sub firing combination. Taking hints from the big dogs for inspiration. On CarAudio.com, Thorshammer has a crazy loud sealed-off trunk. SaturnPioneer built a "death horn" that everybody should read about. On this site, ChrisFish has tested millions of trunk box configurations, Schrummy and AlanHall built excellent trunk setups last season.
The consistent thing with the non-sealed-off setups, is that you don't cram the speakers in... you leave enough space for them to breathe. Pressure needs to "load" properly, but have enough space to flow into the cabin with minimal restriction.

very nice ideas, Thanks. I blew a sub today so the other sub, amp, and component amp are all up for sale. Looking to get some orions HCCA's or something better. I'm starting the trunk deadening tomorrow and post pics as I get it done, I see this as being quite a project. I already have one 0 gauge wire ran for power and ground bout to see about some batteries and go face first into this thing. Main goal being to do enough buying, selling, trading to get another full system and break even as I did with this one. Wood doesn't count (know someone that working in cabinet industry so free finished wood) HERE WE GO!

That's pretty sad about the blown P1. They're delicate subs, but if you keep them within their "happy range" they play well.
What caused the failure? It's either thermal or structural failure. Thermal is more because the signal was clipped (gains/bass boost too high). Structural is if you played too low at high power, and the sub broke apart at a glue joint or other critical piece.
Gotta learn from these things for next time... cause a clipped signal will kill an HCCA just the same as a P1, even if it takes longer.

It was cause the gain was too high I just started smelling burnt crap so I pop the trunk and it stunk bad I had the amp sideways and thought I turned to gain all the way down but turned it all the way up, played for about 4 mins before I smelled it and cut them off. Kinda sad but it was my own fault, guess I know better now. Would that be a simi cheap fix? I mean I broke even on the setup...so if I was to fix it could I still sell it and make what if cost me to fix it?
chrisfish I own this joint!

Thanks Chris.
I forgot about Chilli's crazy build. If he's still lurking, hopefully he'll post some pics of the setup. 156 is amazing for "1000 watts" of trunk mayhem.
poor subs... that's what happens to any sub when you give it a square wave signal, at double the rated power. Using them is a matter of how long and how bad they smelled. If the cone still moves, and the coil isn't too scratchy... give them a thorough testing at rated power (using PROPER gain setting techniques - see CA.com's page for this). I wouldn't recommend reconing them since that will cost more than just buying new ones. If they have significant wear, just delegate them to low-power duty (like workshop or home theater speakers).
