They go hard! Running each crossover at 85w @ 4ohm. Haven't checked what the actual loads are. Will do that when I install the cards back onto my car next time if I remember. The pair of Tang Band 3" drivers I ordered have been shipped so should be here soon. Next weeks job is A-pillars. I am going to make a mould of the A-pillars probably like 30-40cm long, so that the pods that contain the 3" drivers and the tweeters can be removed easily instead of being a permanent fixture to the A-pillars. Stay tuned! Hopefully painting the door cards this weekend!

Thank you! Passengers side door card is almost ready to start going up in sand paper. A few little spots to fill and sand flat then I can go to 150, 250, 400 and then maybe 600 grit sand paper.

Some pictures from today's efforts...

Here is how my car stands as of now... Here is what I bought today to start the finishing process of the door cards and more resin to do the A pillars... I bought a pair of Tang Band 3" drivers which will be going in the A pillars along with 2 tweeters each side.

DAYUM! Look at that magnet! HELL YEAH!

In for this build!

Ported box is done and in the car. Definitely louder than the sealed box!

Yeah I think I will. I have a box sorted now. 2.56cu.ft NET 34 sqin port area x 35". Tuning frequency of 30.14hz. 0.75" MDF with a double stack front baffle. Gross Volume is 4.07cu.ft. Port volume is 1.23cu.ft. According to Torres. I'll throw it up on Google Sketchup now and draw my cutting plan up too.

Really confused ay. Torres vs RE box calc vs my own calculations all give me different figures for the box volume and tuning with a lock port area, length and box size (length,width,height). Don't know what to believe!

Just did that in WinISD and this is what it looked like. Blue is the 4th order, green is the ported I mentioned above.

Yeah of course the port bends but I just thought that 35" was fairly long. Hmmm 4th order, What program can I use to see the frequency response and that? I know theres WinISD but that's not made for car situations. I've got Bass Box Pro but no idea how to use it.

I'm using Torres Box Calculator off this forum. I was going to try for 2.5cu.ft @ ~30hz. But the port length is just huge. I seem to have got a combination on Torres Box calculator that gives me 2.49cu.ft @ 30.72hz (34.80sq" port area x 35" port length). Is 35" a long port?

To get 30hz tuning I need a very long port.

Here's a quick video I took of my system. I wish the camera microphone wouldn't distort! http://www.youtube.com/watch?v=sy3BrFcW4Io

I only used staples. On the inside part of the enclosure I didn't really worry about what it looked like but on the external cloth at the top I folded the fabric underneath it's self and stapled the underneath piece so that the staples were hidden. I will take some tomorrow when it is day light Video coming soon too Thanks for the support and interest guys!
