Review: One thing is make sure you have a place to put the little box - They sound amzing and crystal clear just pair them up with a sub and you have a solid system I put them in a 04 single cab silverado and they are great
Review: Excelente - Chulada de bocinas, no es fuerza, cambiar de estéreo, con el estéreo original suenan muy muy bien.
