I have a 5002 Rockford fosgate amp in need of repair. Where can I send it to get fixed? I have my receipt and early repair papers where it has been fixed by the company. It is 1500 watts. Help!

contact the company and get a list of authorized repair agents close to your location
if there are none and it is out of warranty then find an accredited electronic repair shop and ask around to see if they have experience in your brand of unit

My rockford fosgate T1 amp blew a fuse and now protection is on

Chances are that more than a fuse went. I would follow (internally) the path of the wires from the speaker you mentioned - inside the amp. This should bring you out to the main amp. I think you will find that whatever powers that channel is faulty.

I have a kenwood kac-9152d running a 10 inch rockford fosgate power t1 and the amp keeps going into protect but i have a smaller kenwood kac-8102d running on another t1 and i have no issues with it why...

either the wiring your running is short circuting,or the amp is shot, or the subwoofer is shot, try hooking the same speaker up to the other amp. along with the other speaker to the other amp, see if the same thing happens.

The amp wont go out of protect mode

Sounds like you may have shorted a power mosfet or more than one. I'm pretty sure that is what is going on. I've done it myself. I repair car amps and install car audio systems for a living. You need to test the transistors with a digital volt meter set to diode check. Let me know if you know how to do this, if not I can help you. If you need it repaired and don't know how to do it I'll be happy to repair it for you if interested. I am the cheapest you will find anywhere. People send me their amps from all over the U.S and Canada. Good luck and hope to hear from ya!

About 6 months ago i had installed the mtx thunder 6500d amp to run my 2 rockford fosgate power T1 12inch subs and every thing was great untill recently it stop puting out sound it still powers up and...

good morning and welcome to fixya. not a bad setup you have here at all, you ned to start by checking the speaker wires inside the box to the connector inside and then the wires from connector to amp on outside. if everything looks fine there, then you need to check the amp for power out of the rca plugs to make sure the channel is not dead. if you are looking for a new amp you can try several different ones from fosgates new line up to soundstream's. im running 4 polk momo 12's on the tarantula amp and love it. they are great amps. hifonics also has a new line up pretty cool stuff, heard really good things about there stuff to. good luck and let me know so i can help you out.

Fosgate 4200 amp

schematic is not totally necessary; the two channels are identical with the same topology, just most to comparate it for burned devices.
Example: two NPN transistors for CH1, two for CH2

one npn driver for CH1, the same for CH2

Where to take my amp for repair

Contact Rockford for factory service.

If you don't want to send it to Rockford, ask the local audio shops who they use for amp repairs. If several use the same repair shop, it's probably a good place to send your amp.
