its a 98..if you wanted to sell it you should of done it before it was 13 years old. if you aren't going to keep them why not just remove them now? you can put wood/plexiglass insert into the cab hole.

if they don't fit behind or under the seat then you have no choice but to use passenger space or remove them.

and no all 12s aren't the same mounting depth. being a 12 only dictates its cutout diameter its depth depends on how its manufactures and how large the magnets are.

then either keep them how they are until you have the money, or deal with it sadly



idk if you read it but it is an extended cab:

i did but idk how much room they have under/behind the rear seats. i assume not enough for any regular subs though.

two things i found costs money ofc though

Holy fuck that second one looks sick! Two questions thoygh, it looks like it comes in front of the seat a bit, does.it?

also, can i get sub cages for in front in case people kick them?

another thing lol, my sub depth from top to bottom is 6.5" , it says sub chamber depth is 7", is that enough room?

i'd assume abit yes
you could get grills like:

merely an example this is an 8 in grill though
1/2 an inch would be too close, but i can't say i've never done it closer then that haha
i cant remember if its 1 or 2 inchs it should be away from the side of the box

not from the side, from the back ...

yes from the back

That box looks way to big. it looks like it would be way to uncomfortable to sit on. yes i realize i have 12s

custom made boxes are designed (typically) to use as much space as acceptable in the most convenient place possible (typically) , idk if it would raise the seat at all, but it would be snug
unless their tuned of course
