[QUOTE="KTMrida4life, post: 7598111, member: 637865"] This isn't going to be short and I'm incredibly sorry. I have a 95 Nissan 240sx. Tiny 2 door sports car. About a month ago, I bought 4 SA 8s. One needs a recone, and if anyone has seen my other thread, 2 of the others might as well.. we will see. I had RAM designs do me a box for 3 of them since the 4th one wouldnt fit because of the slot port. I have built the biggest box possible OUTSIDE of my trunk that will still fit into my trunk. It 1.8 cu ft with a slot port tuned to 33 hz. But I want to fit the 4th SA8, and heres where it gets a bit tricky. So Im going to need a new box. Heres the old box design. [IMG]http://img812.imageshack.us/img812/9758/ktmrida4lyfehotmailcomb.png[/IMG] Heres a crappy drawing of my trunk specs (yes, its tiny) [IMG]http://desmond.imageshack.us/Himg163/scaled.php?server=163&filename=trunkdimensions.jpg&res=medium[/IMG] And heres that box in my trunk as of right now. Only difference is right now the box is flipped the opposite way (subs and port facing drivers seat) at the very very back of my trunk (towards bumper) [IMG]http://i132.photobucket.com/albums/q22/Blacknight94/240sx%20audio/DSC_0332.jpg[/IMG] And heres a video of what it sounds like as of right now.. [MEDIA=youtube]IkRio2CcsoA[/MEDIA] It sounds good until I hit about 36 volume and at that point things start rattling so bad it sounds awful. Before then there is no noise that can be heard from the drivers seat. My rear deck flexes because of all the air trying to make it from trunk --> car... even with my rear seat folded down it just seems inefficient. I cant fit a 4th order, no way. Battery in trunk as well as amps. Heres what I want to do and what I need help with as well as opinions, since this is what I want to do and what may not be best.. I want to build another box, almost to the same dimensions as the one I have now. I cant go bigger.. it will not fit in my trunk. I want to use external aero ports. I think 2 4" aeroports will work good. Cant do bigger because port will be too long.. I want to stay around the 30-33hz tuning.
