There looks to be about 2 or 3 inches you can gain by cutting through the first layer of the firewall.

You gain around 3 or so inches in depth. The opening is about 9 or so inches high. You need to seal up each side of the cavity when you cut it out as it is open to the exterior. Be careful of the fuel tank lines running through the cavity on the drivers side.



Mine when I got it finished with 10" subs.

There is no way i would cut into my firewall for the sake of base. May as well call it a party wall as it no longer is a firewall if your engine exploded you will have shrapnel up your butt.

Are you only cutting into the existing trim or are you cutting holes thru into the motor?

The firewall has two layers of sheetmetal. You are only cutting through the first layer. Then there is 3-4 inches between the two layers. That's where you gain the extra 3" noted above.
