Hardest hitting crew cab Silverado

[dolarbilz]

Either behind the rear seat or underneath the passenger and driver seat

under both my seats are heater vents..and some computer stuff..what amps you thinking of using no room there.and if you look behind your back seat on the wall..not hole lot of room..I like to be able get to my amps for ease of adjustment..

I was only able to get a single 8 under the back seat of my 13 sierra while having the amps under the seat too

didn't know he was trying to keep under the seat dang it

My concern is what given the air space that is available underneath the rear seat of a crew cab would hit the hardest to 10 or 12 inch sub woofer's or for sundown audio SA 8 subwoofers? Obviously the eights have more surface area but I don't know if the slight advantage of having more surface area would make up for the difference of having to larger 10"s or 12"s

You can fit 2 8s ported under the seat if I remember right

Doesn't look like near enough port area.

[cabotgsxr]

How can you determine the necessary port area?

[dolarbilz]

Know way that's 2.4

I did mine barely got .75 that was little less than half under the bench..you be better off sealing that port shut finding subs that work compact sealed
