Sonic Sub Box: OCFRD13-10

Very Tight Fit

I thought that this would be a drop in fit but I'm probably going to have to cut at least 1-1/2" off the total height because it doesn't fit under the seat. It also doesn't slide back far enough thus preventing the seat from flipping forward. I'm a little disappointed as other sub boxes for trucks are a little expensive and my only option is to modify this sub box to fit.
Other than that, it is a well built box. Very solid construction that seems like it will last.

Really nice fit

I got the first of 2 of these i oredered in. They are great to fit underneath your rear bench seat because they still leave you the option of putting your amp in between the two like i have. Yes however it is a small cubic foot box so you are sacrificeing some sound. All in all it is a good box for your f150 supercab

Grat box

I bought this box just to fit under the seat which it did. One thing i recommend is using polyfil because it is very small. This box comes very well sealed and it being downfiring makes the subs sound great, box is recommended.

small and worth it

i too have recently purchased this box for my 01 f150 ext. it sacrifice no space and serves its purpose. this box is great. not only is the size good but the price is unbeatable. i priced other 10inch boxes and they have ranged from 279.99 and up. this is practically a steal.
