      yup, i'll be squeezing it in the factory location since it already has a flat area to mount on to.. but there will be some trimming on the factory enclosure and the amp itself..

      i'll post pics of it when i get them done..

      i just downloaded the db804dvc manual and it requires only 0.35cuft on a sealed enclosure :thumbsup:

      based on the information posted here (i'll edit this when i find it again) the stock sub enclosure with a 6.5" factory subwoofer is 9 liters in volume or 0.31cuft.. i just have to add .04cuft to it and it will be up to spec..

      unless the information i found was incorrect :dunno:..

      Add about .25-.4 #'s of polyfill to the enclosure and it should be dead on the Polk specs. You can buy it in 1# bags at Wal Mart for like $3.

      polyfill stuffing like the one they use to stuff bears?

      and what exactly do you mean by ".25-.4 #'s "? is that pounds?

      edit... i found this in our winter closet:

      will this work or is the one from wal-mart a better quality?

      i'm assuming Infinity08 measure was in pounds.. so should i put about 1/3 of the bag in the enclosure?

      :thumbsup: You got it! Kinda' stuff it to the sides to avoid contact with the driver's terminals and any air vents as much as possible.

      got the sub mounted and wired up like the diagram on page 1..

      quick question, it kinda sounds weak/low in volume.. the front speakers overpower the sub.. i am getting bass blockers for the front speakers but the sub still somehow lacks presence.. i'm not shooting for loud loud bass but i want to atleast feel its there..

      the sub is rated at 180Wrms and its wired to give out an 8ohm load to a 360Wrms amplifier..


      thoughts? suggestions on how to make it louder?

      Im using the same box as you, what did you use to fill in the gaps from the "pocket" things in the plastic. When my sub is mounted those holes are still showing a little bit making the box unsealed.

      i had to cut a LOT of material from the factory box on my install.. there were sections that needed filling so i used a sheet of lexan plastic i got from homedepot and started molding it to shape over the gaps, cooled them down, cut it to size applied a lexan adhesive sealant then screwed it in place.. this process ensured a sealed surface but took a long time to do..

      the amp was trimmed down to size too to fit into the space behind the interior panel.. the electronic components were disassembled first and removed before the case was shaved..

      the whole build was done with cargo space in mind.. this was a huge factor for me since i actually use my trunk space and i need it when i move this end of april..


      here's some pics of the assembly:

      finished (for now..) product:

      [​IMG]

      The sub and amp is not maxed out so it runs in the safe zone and the amp only gets slightly warm when used for a long time with moderate-high volume levels..

      bass is nice and precise with a thump.. filling at most and not annoying to the passengers/driver..

      This is what i have. The way my sub fit the box i was able to use silicon to seal the gaps in. I havent installed it into the ex yet, the panel is just sitting in there for a teaser pic. The way my sub(8inch MA audio) is it should fit behind the stock grill with only a little trimming on the lip for the grill. Im not mounting my amp behind the panel like you.

      looks like you already did a great job sealing the enclosure!

      i didnt use any sealant to fuse my sub to the box.. the rubber ring and the felt material did a good job already..

      how about reinforcing the divet with the sealant? it might get loose and create a leak.. it is a little flexible y'know..

      Parad, thats very clean, I like it being in a hidden place yet still being an accent! My friend might sell me one of these cheap, I might end up doing that same thing, I need the trunck space, but I want to show off my pretty little subs :D

      Can you elaborate on that and will the specs be in line with my current amplifier?
