Thread: Speaker Hiss

  1. Update:
    Finally got my dealer to get a response from Tige. Was given a letter that indicated that this was a known issue. There was a bad batch of Wetsounds amps.
    But first they instructed the dealer to check to make sure there is a resistor plugged into the amp. If not they would send it. Presumably this would fix the problem. The resistor was there for me.
    Next, they said to unplug the red and white RCA leads from the amp. If the hiss was still there then the amp was defective. That was the case for me. I even sent a video with sound with the hiss clearly audible.
    2 weeks later and still waiting to hear back. Seems pretty clear that I have a bad amp according to their simple tests.

    An additional test would be to short the input(s) from which you unplugged the RCA cables. This means the amp is receiving ZERO input signal (not even noise). Anything that comes out the speakers at that point is entirely internal amp noise.

    ^^^^, Yep, powering up an amp with no signal cables plugged in can invite noise, leading to a false diagnosis.

    HI, I have the same issue with my 2017 Tige. The Wet Sounds HTX-2 amp gets hot to the touch, even at low volume. That when the static noise starts. I think the amp is bad. I already contacted Wet Sounds. Checked all the settings. I need to go to the dealer, again

    Although the R21 will have some different components from a Z1 and others, most of the diagnostic steps remain the same. Amps to get hot, so nothing necessarily there. So in working direct with Wet Sounds, you were able to isolate the noise to be generated by the amp and not coming in up stream?

    I have no experience with boats, but have done several car installations. If the noise is coming from other electronics on board, the first thing I would try is to put a ground loop isolator for the input signal. Some of high end amplifiers have it built in, but it still worth to try.

    If the noise is suspected to be from ground loop, there are steps to actually eliminate it, rather then mask it with a GLI. If its gain hiss or generated within the amp, it would be post GLI, so no benefit of installing one.
