Carefully remove the 3 knobs and the 1 screw between the 2 10A fuses. then the plastic face should pop off

The 2 boards are held together by 4 screws on the edges of the PCB, gently pull them apart, they will only be held together by pin headers. Here you can see the 2 output filters and the power supply step up transformer

The board with the FEMALE pin headers is the front board with the plugs on it. the crossover network consists of JRC 4850's

There are 4 of these "GA7E1S" FET's that i cant find any info on. i would assume by looking at the boards that 2 are the power supply and the other 2 are the outputs
-
There are NO heatsinks anywhere in this unit which i find amazing. but the FETS most likely use the massive copper planes on the board as the heatsink

The custom 12" driver. it appears to be a DVC driver, but it just a SVC with 2 pairs of leads going to it

Nice, if you can do one on pulling the sub out that would be great. I think it might be glued in.
I have the 10” version of this sub but believe the amp is identical. I’d like to steal the amp from this to use in a new enclosure. Any idea how many ohms this could drive?
Im not sure, when i did this teardown i never thought about doing an ohms test on the driver. it might be a 2 ohm driver, but if you have the 10”, pop the plate amp out and stick a meter on the driver lol
I have a p300-12 , but the box shape is all wrong for my ‘07 FJ. What obstacles do you see after the teardown for transplanting the amp and sub into a custom fit box? Thanks in advance!
i dont see any issues with that idea. just when you get a new box get one thats similar in volume as the original and also sealed as i have no idea how the driver would perform in a vented enclosure. just keep the original rockford box so if you decide to sell it down the line you can reinstall it
