    i read the guide on here for the ssd's, and its a pretty wide range of sizes. I have plenty of room, and was thinking tuning to 32hz and about 16-17 cubes gross. Will be subs up and port back in expedition running off 1 saz1500d. Any suggestions, or does that sound like good place to start? thanks

    I have a 2003 Chevrolet Tahoe and I am going to put a Fi BL 18" in it. It will be powered with a Rockford Fosgate T10001bd amp and a Kinetik battery. Just ordered it yesterday I have a general idea of the specs on my box in order to fit the 5-10 cubic feet. It will be about 9 cubes by the time everything is displaced. The only problem since I am new to car audio and this is my first system is what are the dimensions of the port? The box will be W 45" x H 20" x D 20" with 3/4" MDF. I want to tune the box to 32Hz. Any help will be appreciated. -Kasey

    i have been searching the forums and technical advise.... but i dont see anything about FI speakers in a sealed application. i want to run 2-15's or 2-18's in the backseat (fiberglassed in) of my caprice, however i dont really like running ported enclosures. is sealed not an option with FI speakers?

    I have made up plans for a 6cu ft box, after port and displacement. The port would be 4" Wide and tuned about in between 33 and 34hz. If i made the port 5" wide, it would take the box all the way down to 5.1 cu ft or so to be tuned to 34. The port would be 21.5 in tall. It just seems to me that 4" is small, but then again thats a lot of box volume to take up. I'm really hoping i'm just more worried than i should be about port size, and the 6 cu ft will work out. Any suggestions?

I would like it tuned around 32Hz) http://i235.photobucket.com/albums/ee29/mld42/FiBL.jpg This is a very rough sketch of the box to show where the ports could go. The sub with be mounted inverted for more box volume.

    I traded everything i had about 6 months ago, well, guy gave me good deal on getting all back and some new stuff he just bought. Anyway its 2 BL 18s, and 2 sundown 1500ds strapped. I had subs up, port back, 20 cubes before port and subs tuned to 33hz. It sounded great and definitely had the lows. box before was this: then i had new design done for wall behind front seats, same tuning, and specs, both boxes with 200+ square inches of port, wall box: Both boxes designed by chris at fishercustoms. I never use backseat anyway, but not sure if will make big difference as in louder if i go with a wall. any suggestions? or just go back how it was?

    I have a toyota ex cab truck and I was wanting to know what is the biggest sub set up I can fit in the back? The space in the back is 19'' deep X 22'' tall X and 53'' wide. I want to do a ported box with either 2 Q18's or 2 Q15's. Given this amount of space what do you think I could fit back there? -Alex

    I believe I will be running this amp at 1ohm to my dual 2 ohm sub. Will this sub handle what is said to be 1500w RMS from the SAZ (which I have heard is under rated)? I am not planning to pin the gain or anything, I just do not want to blow the sub.

    This is my current box plans for the 1 18"BTL and 1 Saz-3000d I have. I plan on putting all these into a 03 Tiburon(hatch) and competing in spl. Really my only question is would a bigger box better/ is 5.27 cubic feet enough. Thanks box: (outer dimensions) heighth = 16.5 width = 36 depth = 21.5 port: (inner dimensions) heighth = 5 width = 7 length = 10 this port will tune the box to about 34.67 hz which is what i personally like to tune mine to. after port displacement...this will give you about 5.27 cubes of air. so you have room to brace it and not go below the recommended volume. this is also assuming that you're using 3/4 MDF. competition port: (inner dimensions) he…

    hello, If anyone can tell me the port length for a 15inch fully loaded BTL that would be great. they took down the specs for the new woofer i guess, making it unable for me to read it. So if anyone can tell me all the port information for a 15inch btl i would really appreciate it. Thank you

    I am having problems with my btl's. It just started recently, when i listen to music the subs start to make loud popping sounds, Instead of a flow of bass they pop. But if i play just a tone then they seem to be fine.

Forum members have told me to talk to scott or nick at Fi car audio to get some. Seems they might be busy since i didn't get a reply. Hoping they see this and respond back. thanks
