I have two RE SX 18s that I want to throw in my truck. Sites any have any experience with this type of setup? Like subs in the bed ported into the cab.

Technical name is Blowthrough, google blowthrough silverado and you should come across several in depth build threads.

I looked though those but all I seem to find are for 15s. Ive only seen a couple with 18s but just demo vids ya know. Ive got three 12s in a blowthrough now, but ths are the first set of18s ive owned. 10s 12s and fifteens ive done.
