Ideas to upgrade sub from FI Q 12"????

[jeeper2269 10+ year member]

I've had a 12" FI q in a custom built sealed enclosure to spec for about five years now. I'm running a JBL bp 1200.1 mono block to it, and I'm just wondering if I should upgrade.

I want to keep the same size box, but I want it to perform better. Maybe it's just worn out???

On a side note,,, I've always dreamed of having a Cerwin Vega Stroker

The series that pushed 162db or something crazy years back.

Btw, it's in a 2011 tundra double cab. Basically sitting diagonal under the back passenger seat. Sounds best that way.

Your box is what's limiting you..... Get one built around your cars cabin gain and you will see a difference.

What? Cabin gain?

Sorry. I honestly don't know what you mean. I would pay to have someone build me a box custom under my back seats. But I don't know how much more cubic inches it would be from the current one I have.

Cabin gain is basically the frequency that plays loudest in a vehicle. It's not actually a frequency but the phenomenon that causes a gain in output. Each vehicle has a different frequency. Cabin gain is based on wavelengths. Smaller vehicle more gain. There is so many variables that you should just do some research. This forum provides a lot of info on it.

Thank you. I will research. Maybe someone on here has already built a box with maximum output for the same model truck I have
