ok i have single cab GMC Sierra and i wanna put 2 subs behind the seat that will slam pretty hard. i also go tailgating with my highschool before football games and my truck is our music so i want something that u can hear pretty good outside with the doors open. i have about 11 inches behind the seat with the seat all the way back. my budget is about 600 dollars. what can i put back there that will slam!!!
i would prefer 12s but if u dont thik it will work then 10s will be fine.

What amp will you be using? What is the available height and length? Can you put the amp under one of the seats?

What year is the truck?

I use two 10" Treo SSI under the back seats on my Titan. They have a 5.1" mounting depth so they can work well in a shallow enclosure. I paid about $275/ea for them but I think you can find them cheaper now. They may be a little hard to find but I would really look at them as a small enclosure/high SPL sub option.
