wtf......lololol

nice how many cubes is that box? and how do the aluminum coils performer over the copper?

yes forgot to mention this. so if you will be overpowering them then a smaller box is okay but if you are just doing the Rms then bigger it goes

and if you really want mid bass you could make custom door panels for your front stage with an 8 on both sides followed with some 6s and tweets but then your talking some $$$ and work

tuning lower is to hit lower notes. but if your looking for more mid bass don't look at your 15s for that much help. sure you can tune to 45hz and hit the mids if you want but the bass would fade away on a lot of songs. and the vvx is skar audio right? well they are based off of the sundown sa line but have there differences but i know Sas can be put in a larger box no problem. but i don't have any experience myself with the vvx line so they could be act different.

dood in this thing i would pick up a 2nd vvx and build a big box around 8-9 cubes tuned to 32 hz with a bottom slot port.

yeah this is in a trunk car right? and yeah sup up port back is fine some don't like it but with 15s and 18s sometimes you don't have a option. and i would check out Audioque as well you can tune them higher and they still hit low.

if it was tuned to 28 it should be hitting the lows. how much port area per cube do you have? and make sure all your crossovers and filters on you amp and head unit are set right.

how much room do you have for this box for the 18?

yeah when ever a car has 6x9s they are all you hear because the sound hits the rear window the goes to you. but i would say to get a amp for the 6x9s and 4x6s then get 4 small tweeters to run off of the headunit.

yeah that thing is a monster!

yeah also look into better speakers them self that can take more power. then throw the right 4 channel amp on them.

don't get so snippy bro but i would suggest a good 4 channel amp for your mids and highs first and then go from there. trust me there is a BIG diffrence between head unit power and the power of a 4 chan amp!

lol nice

cool stuff i want to see how it dose!

Noice!

yeah it tuned out really nice. Maby get some thicker stuff like these guys said but other than that great job.

And if you have your heart set on a 18 try to get at least 5 cubes after woofer/bracing displacement.

ahh alright. yeah i would just look around and check ebay.

/\ doesnt that depend on sub used and the the amount of rms he pushing to it? not to mention if he wants sound quality or spl...... yes there are many variables in the size of the box but an 18 will need a big box eater way.

what are you worried about? do you have stuff floating around with it?

i am 99% sure you will not be able to fit a 18 in that car with the proper size box. with that being said i would get a 15" look at the audioque sdc2.5 and hdc3 15s and yes you will want to do the big 3. and if your running less then 1000 rms then you should be fine with stock alt and battery as long as you done the big 3 in quality wire and that your amp is powered by 4 or 0 gauge wire and is grounded properly.

don't. the only door mod i would do would be suicide doors.

i really don't trust most stereo shops. and idk about sony and yeah you will most likely want to run a amp to them.
