I just installed a N4 2000 watts at 1ohm it has all kinds of balls I replaced a jbl BPX 2200.1 and I'm happy. Let me see how long it lasts!!

What kind of drivers? Weird design my designs are most of the time like 40 60 or 50 50. With about 20 sqin of vent per cube I like a curve with a nice plato. I use drivers with a EBP rating of 70 or less work best .EBP is fs/qes.

I need a JBL bpx2200.1

Cool let me no

Its a good start for a beginner bro no shit they don't all sound good like that. But it would be a good point to start with. And then he can fine tune it on your calc or winisd

Its not rocket science. Download winisd it a free windows based box design program. If you want a simple formula for ported boxes just do 12 sq in of port for every cubic foot 24 inches long it will tune you right between 32 and 34 Hz every time

Ok its mad easy do 1.75 sealed plus driver displacement 2 ft3 on the ported side with a 40 sq in vent 11 inch long ad for port depending on how much of it is in the box. I like to build it the classic three chamber way. I have not tried it in a non trunk vehicle I would like to no what it dose. I have used all brands in this design no one has ben disappointed

I build boxes I'm in miami hit me up [email protected]

I guess you are right. Its louder with the windows up to just like my boys trailblazer. I'm going to do a 15 in a honda fit what works best?

Yo I got a sick design for two 12's. What kind of car? I do it in challenger, camaro's and s550 it bang's nasty and gets super low. Hit me up I would be glad to help. NO TRUNK NOISE

I have a accord wagon with a prototype 15 on a JBL bpx2200.1. With the sub up and vent to the pass side. I have had the best results this way. Loudest and best sounding thing I have had on my amp to date

What size are your factory tires? And then we can calculate what can fit. Also measure how much space you have between your factory tire and any suspension components front and rear.

How to calculate overall diameter. Example 305/30/26 305 divided by 25.4 equals 12 times .3 equals 3.6"times 2 equals 7.2 plus 26 equals 33.2. So your tire is 12" wide and has a overall diameter of 33.2"

I would do a 38 sq in vent 23 inch long. That would put u right 34hz with your current dimensions. Also make some brackets to space your back rest out about two inches or so at the top and take out any insulation between the back seat and the trunk and use allot of sound deadening on the side walls and trunk lid.
