I recently upgraded the audio on a new JP premium using the info on this thread which made things really easy. I created my own CN5 connector and 3D printed the speaker brackets for the backbox. I'm powering the amp from the service port since I use smart plugs to power my games.
Here's what I used for reference:
Amp (Fosi Audio BT30D): amazon.com link »
Backbox speakers (PYLE PL53BL Blue Label): amazon.com link »
Cabinet Sub (Pyle PLPW8D): amazon.com link »
Huge improvement over stock.
Quoted from pete_d:Active sub, but external and powered by mains outlet.
Phase three of my upgrade plan hasn't been executed yet, but I plan to add a switched outlet inside the cabinet for a powered amp to run the cabinet speakers. I'll do this by adding "piggyback" quick-connect connectors to the switched side of the power switch to tap the mains power there, with those attached to the receptacle end of a power cord, so I can plug a regular power supply adapter for the amp in there.
I have seen posts about how to take 12V from the pin itself, either from the power supply or the motherboard, but either of those -- especially the motherboard, but also the power supply -- make me worry about exceeding the designed spec of the power in the pin. Theoretically there should be headroom to accommodate an amp, but the amp can draw a fair amount of power, and the pin manufacturer has incentive to provision their power supply components only for what the pin itself needs. I figure better safe than sorry.
Since my pins are all powered through smart plugs (amazon.com link ») I just plug the amp's DC power supply into the service outlet.
Has anyone had issues with the Fosi BT30a amps? I've got 1 that is perfect, 1 that is a little noisy, and 1 that is really noisy. I've swapped amps between games to rule out any cabling and power supply issues and the noise follows the amp. I've got the worst of the amps apart now to test it, but I wanted to check if anyone had seen this too and figured anything out.

I replaced one of the bad Fosi BT30D's with one of these DIY TPA3116 chip amps and so far so good. I'm still using the Fosi power supply.

No idea yet what is going on with the 2 noisy Fosi BT30D amps. I ordered them at the same time, so maybe these 2 are a different design rev from the first one I bought a few months back. Or they started using some lower quality parts.
