Thanks, that info did work.. Oh yeah I edited the first post with pics.

2 6" ports 26.8" long 26.8" long each? what kind of displacement will that take up?

Sorry to thread jack a little, but I need to know also for my case. I will be running a 15" BL in a 3.5cuft box what size 6" port would I need? 1 or 2 6" ports? how long? Thanks

Sounds like many experiences I had so far. Not even with the 15" Fi BL sub that I will get whenever it gets shipped out....thats a different story. BUT in my little Scion tC, there lies a box that is ~2.5cuft ported to 32Hz with a 12" RE SX in there powered by a RF T10001BD. I remember this one time a little car show and they had a db drag, I line up and bust out a 139db. People was like WTF you have in there? 2 12s?.... I was like no. Even the people that ran the thing wow that is loud for a daily driver set up what do you really have in there. I open the trunk to their amazement they see a single 12". Everyone jaws dropped. Even the guy that ran the thing he had 2 12" DD in his sunfire and was barely able to pull off 140db... felt bad for him. I ended up taking 1st place over all and 1st place in my class. All for one measly 12" sub. Not to include all the car alarms that I set off with that setup... Can't wait til I have that 15incher in a 3.5cuft box tuned to 30hz, I will make the girls happy. Hopefully it will be loud enough to do some hair tricks!! 15" BL sub with 1500watts from T10001bd... ????db... only time will tell

Cant wait... Getting antsy by the day here!

I just ordered a 15" BL with cooling, flatwind, and unversal. Along with a recone kit for a 12" RE SX sub that I will sell after I recone it. So that 15" BL will be powered by a RF T10001BD whenever I get the amp back from RF, warranty work... That BL will go in my Scion tC, hopefully I will manage to build a 3.5cuft box and do an external tube port, and port that to 30hz. The reason why I want to do tube port is so that I can change it and tune it higher for competitions. I'm just hoping that that box can fit since the Scion tC trunks are kinda small. The box that I did have in there for the RE was 2.5cuft already. With the new box I will remove the spare tire and hopefully that will give me more room, it should. Hopefully I can break into the 140s with this setup. When I had the 12" RE SX in that box which was tuned to 32Hz, I hit 139db@42Hz on a TL mic. Only time will tell.

So does this sound right? For round port using this calculator http://www.carstereo.com/help2/Articles.cfm?id=31 For box that I will build at 3.5cuft tuned to 30hz it says to use a tube in with a length of 7.83" and a diameter of 4". Does that sound about right? Or not? Or for a slotted port it calculated for a 3.5cuft tuned to 30hz, do a 6" high, 4" wide, and 14.49" long. I'm confused..........

Its a hatchback! My amp is repaired by RF, hopefully getting that back soon. Hopefully get the BL soon and start building that box. If not imma throw in my RE back in temporarily when I get that amp back. I just got a new HU also the pioneer avic d3. We'll see

Yeah the sub facing up is the only way to go with that 15"er, just because of space issues. Unless my calculations are off, but I have to really measure it when I take everything out of the trunk. Reason for the external round port is because I can tune differently if needed, and it will be a less of a complicated box. I'm just hoping RF will fix my amp though. I don't feel like spending $500 on an amp right now. Can't wait to get the sub in so I can at least start the build for the box. Sub facing upwards and port facing the rear tail light.

Do you have pictures of your trunk?
