Wall set up. Want it to be loud on music, I have no budget will pay anything to get best quality and vehicle is a sebring I have a video of currentf setup also on youtube as holychips7. Build a wall, What dimensions do you have to work with? You could get two more TI's and a bigger amp, that would probably be cheapest If it's still not enough, replace TI's with some othrer 15s Honestly the possibilities are endless when you have no budget or space requirement No Budget means everything is available for you, do you want a wall or trunk setup?
