I'm not even sure if it should be ported or sealed so I'll let you experts decide that. Only thing I ask is that the depth(front to back) not exceed 2 feet, otherwise doesn't matter. I'm replacing 2 10's that don't hit hard or low enough anymore. I would go 2 15's, but why wouldn't one suffice and I only have to sacrifice half my trunk? I'm not looking for a competition, just very low deep feel it in your *ss bass. I listen to mainly R&B, a little rap, a little smooth jazz. Thank you!!!
