yeah I'm gonna seal it off because that would help out the most i think and as for the psi recone if i get it done it will be a more efficient recone and it will be dual 1 ohm so i can get about a 0.7-0.9 ohm load after impedance rise and hopefully that will give me more output than being run at a 1.3-1.4 ohm load and plus the added efficiency of the recone might help. and yeah your right it wouldn't really do much if its completely sealed off from the trunk.
The recone would help you get more power into the sub, you just gotta ask yourself if its worth it to you. The recones arent exactly cheap, shipping alone is like 30 bucks, haha.
Th "Cleanest" way to do it would be an even layer of spray foam covered with sound deadening to make it look better.
Also keep in mind, dropping below 1 ohm is ALOT more demanding on your cars electrial system... I would make sure you have the big 3 done, and a second battery.
Yeah I live in memphis which is about 20 minutes away from psi's shop so I can drop off my sub with dave at psi and he told me around $120 for the recone and I have done the big 3 and I'm eventually going to get a deka 9a31 for a battery in the back then I should be golden as for keeping up with the amp. Also wouldn't spraying that foam stuff leave a huge mess if I ever want to take out my system?
Yup, it would leave a mess, lol. Im sure there is a way around it though... maybe put a layer of alminum foil down on the parts you will spray before you spray the foam?
Should give you a tight seal, and should be fairly easy to remove when needed.
I have never done it, but im sure someone who has done it will chime in
it takes a lil more work on your part but me and my brother did something like this to his car like they are saying make a frame slides over the box and once we got it fit, we took some super wood slide it under the box fiber glassed the corners that kept everything neat and in order so when we put the foam in it didnt get all over everything.and just got a beauty board to cover the front . i think he metered a 144.6 with 2 10s on about 2k
