MTH GP38 (PS2 Engine) Sound problem

Ditto what G said.  I've replaced 3 of speakers already.  Two were flaky, one was not.

WAS THAT SPEAKER A 16 OHM 5 WATT? i HAVE ONE OR 2 ALSO THAT IS STAICKEY

Is there a way to determine if I blew the amp?  I had an extra speaker from a mth crossing that I tried to temp in to see if there was any sound from the speaker... Nothing.

Is the 3 wire volume pot still connected to the harness or any wires broke off?  Did you turn the volume down with the volume pot (conventional) or DCS?  If all that is fine, it is possible the amp blew.  G

Mine is just the engine sounds that are unclear and weak. Mine is the GP60 MTH prot 2

I can fix this for you.  You can contact me off line, my e-mail is in my profile.  I am ASC tech.  The pink wire controls the smoke unit via the switch (conventional only).  The lights going out are an issue, along with the original no sound.  Did you try a factory reset to get the lights back on?

After a forum search I came up with this thread. Apparently I'm having the same issue with a PS-2 engine DAP BNSF GS-4. Haven't run it in a few years, fired it up, and sound quality is horrible and very low volume. 5 watt, 16 ohm and the magnet is covered in grey flaky dust looking stuff. Speaker is very crackly, low volume, and no bass what so ever, the only noise is a high freq crackle.

After reading through this thread, it's a cheap $10 speaker. Anyone have one? or is there a better replacement for even better sound?

Well a quick swap out confirmed that its a bad factory speaker. The one I put in there was a 3 watt, 16 ohm because that's all I had. I just did a quick test to confirm that was the issue.

What kind of damage will I do if I leave that speaker in there? Blow out the amp for the sound board?

I have the speaker in stock.  You can e-mail me via profile.  Yes, the magnetic residue can get on the board, also always a potential it shorts the speaker and overloads the audio amp.  G
