Hey - hopefully you are still doing box designs...
I plan on installing a Kicker Solo x 10" in an 04 Tahoe. I will be keeping the 3rd row seats functional and have been in contact with Kicker and these are the dimensions given to me from them.
Ported 31” w x 22”h x 12.75 b 9” t (break starts around 16"h) - the sub will be side firing towards passenger side
Port 4” x 10.5” opening x 19.75” long - port is to be top firing forward into cab of truck.
Tuning will be at what you design (would like for it to hit hard but will mainly be used for ed listening)
Your help is greatly appreciated!!!
