Hello. My T2500-1bdcp went up in smoke a couple days ago. I've taken it apart to assess the damage done and to determine what may have caused the problem. After disassembly, I immediately noticed two of the larger capacitors rolling around inside, fully disconnected from the main board. I'm thinking that they may have broken off causing the issue to happen. My car has very tight suspension, and I must admit that the amp probably suffered from the beating of the tight suspension. I've also checked the other large capacitors, and one of them is slightly loose on the board.
In addition to the capacitor issue, almost all of the IK29AD 75344G Mosfets show signs of damage. I'd like to order the parts to fix this amp.
My question is, how do I need to go about checking other devices that may not appear to be damaged? I know the process of checking for shorted/open mosfets, but I'm wondering what I need to look at on the smaller components. I must assume that there's probably more blown than what the eye can see.
Thanks ahead of time for any information you can provide.

The caps break loose from bass. This is a common problem. I'd suggest replacing the 3 in that group. The other 3 may have breaking/broken connections as well. After replacing them, use an adhesive like GOOP or E6000 and bond the tops of all of them together. You can apply adhesive (just a small amount at their base as well but it's not generally needed.
Check the output transistors for shorts.
The gate resistors and possibly the drivers for the power supply resistors often fail with the failure of the PS FETs.
