Have you done the big 3

If you wanna get Loud with decent SQ then try an xcon. Is there a reason for wanting to go with fi only?

Ok thanks. My plan for now is another stock alt with the big 3 done. I hope that works ok.

a box should be super easy to remove if you build with a terminal cup in it. All i have to do to remove mine is unhook the speaker wire then lift it out. So as long as your box isn't shoehorned in there or bolted down you should be fine.

Letting us know how much space you have would be helpful also some pics would be nice. If you don't mind rigging it you could mount your amp somewhere then just take your box out when you need to, but once again im unfamiliar with your trunk space.

ok thanks. Do you think 150amps would be able to support 1000-1500 watts rms?

well everything was fine until i put the amp in then about 2 months later the alt quit charging so i went to the junkyard and got one then that one went in about 2 weeks. I just thought it was a weak stock alt, its only 65amps total.

I have a 15" sub in a box that is 4 cubes before port and sub. The box has 2 32" ports. I tried google and the search function on here but i couldn't find a way to figure out the tuning frequency of the box. Thanks for the help If any more information is needed please let me know.

Ok so i figured out these dimensions that give me a tuning frequency of 33.5hz A volume of 3.97 cubes after subtracting sub displacement, and i think that the RE calculator automatically subtracts port volume. Another question is are the measurements i input to the calculator Internal or external? Anyone have experience with this calculator that can answer? Thinks alot for the help.

Ok thanks. I just don't know if ill have access to a router to make circle cuts. thats why i was going to use a slot port. I just have to figure out how to determine the size of a port.

Well i was planning on making it bigger because if i remember right nick at IA told me it should be around 4 cubes optimal. Is there an advantage of using aero ports? A slot port would be easier. the dimensions i listed were after subtracting the material. If i change the interior dimensions to 17"x23"x20" that makes the total inner volume 4.5 cubes. Would that leave me enough room to give it the proper port to tune it any where from 32-36hz? I have enough room to go an inch or two bigger on the height or width if need be?

ok thanks alot. Here are the dimensions of the old box The inside dememsions are Depth 16" Width 21" Height 20" The box is 3.9 cubes It can be a up to like 4 inches wider and my be 2 inches taller I wanna keep the same depth. its going in the trunk of a crown vic. Thanks again.

How do you all cut the mounting hole for the sub? Router? If you don't have a router is there another way to do it?

Well im going to build a new box thursday. Could somone here please help me with a design. I just want something simple atleast 4 cubes net, and tuned to 33hz instead of the ridiculous 53hz its tuned to now. I was also wondering if i would notice any more lower end output and I wanted to make sure its worth the trouble to rebuild a box. I didn't want to clutter the boards thats why i didn't start a new topic. But thanks for your time and if you need anymore info just let me know.

ok thanks. For the time being it doesnt matter anyways because my alternator fried.

Any thoughts on this?

Would i be able to Take off the ports and go with a new port design? Like replacing only the wall the sub mounts in and taking out the old ones. Would i notice more output at lower frequencies if the box was tuned to around say 35hz? thanks for the info.

Well the 57hz tuning would explain while its so much louder on higher bass frequencys. I guess i messed up when designing it. And the demensions are all after i subtracted 1.5" for the Material. Its a real shame i phucked up the box design because its a super nice box. Heres a pic.

This is a picture i tried to draw in paint but for some reason it came out small. The inside dememsions are Depth 16" Width 21" Height 20" I dont know if i measured the port length right or not but i showed how i got it in the pic. Its 12" The box is 3.9 cubes

This sub is great. It is my first sub but ive heard other setups with 2 10's or 2 12's and its been louder or just as loud as the ones i hear with low but tight bass I have it in 4 cubes net with 64" of port area powered by a kicker 300.1. I cant wait to get a bigger amp to see how this thing handles it. Also i would recommend this product in a heartbeat especially for 130 shipped. Sorry if this isn't a great review but thats why i didn't start a new topic for it just thought some more input would be nice. Also i almost forgot to add how helpful Nick at IA was in answering all my noob questions promptly and completely and my sub arrived in about ten days.

Im gonna measure it tomorrow when i get out of school tomorrow its dark now. So you need length width depth and height? How do i measure the port length? Once again thanks for the help.

It has two ports with thirty-two inches of port area for 64 inches of total port area. I have to measure the lenght today.

I dont mean to jack the thread but what about the CRX makes it such a great spl platform. What if any charateristics should one look for in an spl oriented vehicle. Once again sorry for hijacking the thread and just thought this didn't deserve its on thread.

caraudioforums.com is where i found out about it.
