Ford ranger extended cab semi-wall build

[bunkrd you 10+ year member]

built a battery rack for my yellow top d31 to sit on top of my deka. I tripple grouded my deka and used the machined posts as a d block for grounds and have two grounds to my seats that are grounded through to the chassis, two to a rear seat belt mount which also goes through to the chassis and two grounds up front to the chassis, and engine block. 4/6 of these grounds are in 2/0 and the rest in 1/0. I just ordered a us md3d and it should get pretty loud in my new box. I had a md1d previously and liked it hence why I bought the md3d.

Also decided on polk components and a kenwood head unit.

Polk Audio MM6501 - 6-1/2" Component Speakers System - Sonic Electronix

Kenwood eXcelon KDC-X794 (kdcx794) CD/MP3 Car Stereo Receiver

Can I bridge the components which are 2.7 ohms into the alpine mrp220? or would that ohm load be unstable?

Three 3" ports for four 10's? //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

What are the dimensions for the box?

edit: I see that they're 4" aeros...still a little small, but should work alright.

lol already almost done with my second box i only had like 36 sq in of port for 7+ cubes. I now have 91 sq in on a slot port design with 6.3 net cubes tuned to 31.6 hz. I also used 2x4's for bracing on my first box and now am using 3 1.25 in dowel rods for less turbulance. Box is turning out a lot better then the first just because I took my time more and lined up all the screws to prevent splitting. Another thing I did was for the sub cutouts I had it so when the grills are on the subs they all fit about 1/32nd of an inch apart so It looks a lot cleaner. Amp will be in this week, and the components, alt, and hu will be in in around a month or so.

one brace is going in the center, the other on the center of the 2nd length of port and the other to the right hand side. I just dont want this box to end up falling apart on me. I will paint this like I did the first box because I tried another brand of "stone" texture on my most recent fail and it didnt look near as nice as my other box aesthetically speaking. I cant wait to have teh dbz in my truck again. But my mids and highs have been SCREAMING since my most recent tuning. I just need a foth speaker amp for my stock speaker locations. Pry just end up doing a 2 channel to my infinitys in the door and leave my rockford 5x7's on hu power seeing as though they are so drowned out in the back with the box/batterys/wiring.

so far so good

tuned to 32.7hz with 6 net cubes with 91 sq in of port

so after an hour with the cutouts using a hand file and sand paper I find out my dad had a dremel this whole time. Ended up taking me 10 minutes further with 2 subs to go and prefecting the other two. Front is double baffled and I braced it using 3 1.25in dowel rods on the second length of port, and bracing along the front.

looks much better than the first

Almost done with the paint just another coat of black and a clear coat. I also used a different brand of paint for my second box, but i liked the final texture of my first box so I went with that and this box is looking sweet. will have pics up tonight,

 

[bunkrd you 10+ year member]

Done.

ill do one better Vids. But i just have a 3.2 megpixel camera on my phone. I just need to get a digital but the terrible pics are just to show that i am making progress. I am building a buddy a free box for 2 12" w6's just to get some references out there. Thinking about tuning around 30-32 hz with 3 net cubes. He is the one i sold my 2006 md1d.

 

[bunkrd you 10+ year member]

I know lol everything thus far has felt like a teaser. 1000 watts in a weak box and 1000 watts on too small of port area. Now I have the box and amp its game time lol.

Last question can I run the polk's bridged even though they are 2.7ohms it says it can be ran off hu power so i am assuming bridged at 2.7 wont be too bad. The amp is an alpine mrp220. If not I will run my door coax's off of it and get another 2 channel.
