alright so i bought an amp off of ebay and it was listed as "as is" i didnt expect it to work nesessarily but its missing the 2 capacitors off of the board i was just wondering if any of you know where i can find a wiring diagram or even better if anyone knows the part number off of the capacitors. the board is printed with C11 and C12 as the indentifiers for the caps position, there are only 2 of them and they are the only large caps on the board. the amp is a kenwood kac-8401 4/3/2ch 640w peak 60w X 4 @ 4 ohms with a 40A fuse

thanks im kinda lost on this one

Do you suppose those caps are gone but everything else is just fine? Seriously, if your intent is to learn electronic repair, then ok, start taking courses. But if you want an amp for your car, this is not the route to go. Sorry, bad move buying "as is" off ebay.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

the caps are gone as in they were taken off the board prior to my getting it. im in the process of troubleshooting the board with a tracker and it also has some blown transistors that im ordering. i just want to know if anyone knows the part number for the caps or the specs/values for them would work too.
