I havent hooked up mine yet, but I plan on using the dual front speaker setup that bolts up to the single center section. For the back...well...the prior owner cut out two huge holes for what look like monster 16s. Ill probably look to bolt up something into those existing holes, or, replace that back panel and do as someone else here suggested and merely lay speaker cabinets in the back seat floors. I did have some kick panels that were already pre cut, but, I sold them with another project (I didnt like the way they looked anyway).
