You must replace all 6. Don't try to re-use the ones you replaced. Install 6 new, unused transistors.

Check the gate resistors to make sure they're within tolerance. Do this after removing the old FETs.

You should not apply power to this amp without having the bottom cover tightened down on the amp. When you power up the amp, you should do so through a 10 amp fuse.

If you're new to repair work, you should read the basic repair page (link below).

Yes, a 10 amp inline fuse.

What do you mean by different numbers?

For the new Z44s, they should be identical (identical part number and production/date code). It doesn't matter if the old ones had different date codes.

I did what u said and it came on with some buzzing sound out of the round thing. I hooked it up in the car and it was pulsating the power and extruding the speaker in and out, any IDEAS?

Did you check the output transistors to see if any were shorted?


Did it blow the 10 amp fuse when you powered it up?

Does the power light pulse if there are no speakers connected to the amp?

Does the power light pulse with no RCAs plugged into the amp?

YES I checked the output tranisitors and they all work properly. It still pulsates when you unplug the rca wires,it stays on with full power.It does not pulsat power when the speaker are unhooked.
