Hey guys im looking for a sub setup that will fit underneath the back seat of my mark lt. i know it sounds pretty simple but im not sure where to start i will get an amp after i decide on what subs i plan to run so i can get the right amp and not be limited because of it. So here is what i want i would like it to it underneath my back seat, and if posible it has to be louder than my dads excursion with 2 jl audio 12w0's and louder than my friends car with one 10w6. I dont mind if it is not too clear because i listen to mostly rap and i would just like a lot of bump, but on the flipside i dont want some ****ty sounding setup. If you need any more info just let me know, thanks guys.
