Going to build another box for my 2nd car.

34 wide x 15 high x 19.5 deep.
3.75in wide port x 39.5in long
50.5sq in port area
3.4cf according to re calulator
29hz tuning frequency

I will be dropping 2 12in jbl subs, not sure which ones yet.

Just want some advise if I would be ok with this and will be using an incriminator audio 20.1 @.5ohm to power them

I was thinking of the jbl gto 1202D but worried my amp might murder them.

As I always buy small cars, Im always limited to small trunks.

what amp? thoze subs are rated for 300wrms. Murdering them haha bro i have two cerwin vega HED 12's on one fusion ppam2000.1 wired to four ohms and that thing gives them more than enough power. what amp?

oh and if that is the biggest you can go then go with it for those subs.

Hey d_man, I have an incriminator audio 20.1 and wanted to get 2 dual 2ohm subs so I can wire them to .5ohm, I think that will definately get them going hopefully not murder them LOL :) and at 29hz I'm curious to know how they would sound in the box in my 1st post
