    • Crossover / Gain

    • Power Supply and output FET's

    • Power Supply Transformer

    • Output Filters

    • 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?

Ian Pitts - 回复

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!

Jason Todd - 回复

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
