Default Rockford Fosgate T5002

Anyone know the values of R1042 and R1043 they sit directly behind the bias pots ?

604 ohms.

Although it doesn't hold for all of the newer Rockford amps, in most amps, you can look at the counterparts in the other channel to find the value. In this amp, 1042 and 1043 are the same as 2042 and 2043.

I looked at the other 2 and all 4 were burnt in 2 pieces..

Left channel has very distorted output

Right channel has no output..


I replaced the resistors and they burnt up within 2 secs of power being applied..

So i guess i will have to take a look at what connects to them

Email me if you want the schematic diagram for the amp.

I replaced the A06 and A56 that connects to the 604 ohm resistors ..

Replace both resistors again and within 2 secs they burn up again..


Any ideas>?

It would appear that the bias transistor is not doing its job. It could be open, missing or has a bad connection between the MEHSA board and the main board.

I fixed the broken connection between the Meshaboard and the main board..

Amp is still burning up the resistors..


So at this point should i just replace the bias transistors since both channels are burning the resistors up ?

Did you conform, with a meter, that you have continuity between the legs of the 3-pin jumper and the bias transistor?

Short the bases of Qx016 and Qx017. Does that stop the resistors from burning?
