arc 125.2 amp on bike…. i have no sound…when i connect speakers directly to head unit i have sound….can i deduct the amp is bad ? is there anyway to read outputs ?

 

1. Does the amp have power?
2. Are the amp inputs connected correctly?
3. Does your exhaust sound good enough to overlook the malfunction?
4. Do I really have enough coffee on board to reply at 7:10 on a Saturday?

Do you have DC power at the amp's power terminals? That'd be the first place to look.

 

have 12 volts and a power lite on the amp… but no sound i assumed it was the head unit had stopped working (still had display ) when i lost all sound , so i replaced the HU with a sony mex -m70bt but still no sound until i hook speakers directly to sony, bypassing the amp

 

How are you connecting the amp, with the HU speaker outputs, or with the preamp output?

I wish I could just buy new stuff when something small goes wrong lol.. Well honey the car needs new plugs .. I'm gonna go buy a new one. I had an amp in my old trans am that tested fine for every test I ran untill I noticed that both rca outputs **** the bed.

 

had the arc running of hk head unit for 5 years thru the speaker wires (not rca ) just stopped putting out sound ….amp has power and head unit has a display on it so that must have power also ….new head unit still no sound unless i bypass amp …. hard to believe both speakers are bad

 

When I bought my bike recently had a similar issue head unit works no sound, I'll be watching

 

Have you tried RCA's?

 

Lol. . . Stick another amp in there. If it works your amp is bad. If it doesn't you have another issue.
