The box with a little modding (taking out a tiny bit of material, sorry fox) will hold 2 alpine r10s. And with the right amp they can be overwhelming in ever sense of the word. I slightly modified it more and stuck 2 massive audio summo xl 104 in there and it makes your skin tingle. It makes your mouth vibrate. If left how it was taking a 1/2 inch in a certain area (the brace) on each side the alpine r10s are monsters in there! You can stuff some short skars in there but what are you a bass head or a meh head. Took 30m with a knife to notch it out. I wish there was a way around this but there isn’t. The box is epic! With F150 branding and made in the USA on top. Doesn’t get much better than that! And these guys are awesome! Customer service is awesome.
