Amp Troubleshooting...
Hey All! Hope everyone is enjoying this spring weather! Winter 2020 I installed some GZ Yellow Baskets in the fairing of my 2015 Ultra Limited, and a new amp (DB Euphoria EX4). The Eurphoria powers the two yellow baskets and a set of JL Audio marine speakers in the lowers. The amp is not bridged, paralleled or anything else like that, 4 speakers, connected to 4 channels. Also have a Dayton 408 connected to a Sony AX-7000 before it gets to the amp.
I didn't do any riding really after install of the amp and yellow baskets, but recently we had a ride out here of about 180 miles. The first couple of hours everything was working great, but then the front sound stage (both uppers and lowers) started cutting out periodically then coming back for a bit then going out again, and it seemed like if I kept the volume down it would stay on, but turning it up caused the issue.
I'm thinking it's either thermal or perhaps gains set too high? Gonna pull the fairing off this morning. I can jiggle wires with the best of them to check the electrical/speaker connections but if the amp is cutting out due to protection I'm not sure how to test it other than cranking it up for a fair amount of time which would be sub optimal in my neighborhood
.
Thanks!

Make sure to follow the sticky on how to set gains. Not saying maybe you dont know how, but its easy to miss something like pulling the speaker wires when using a test tone. Not good lol

Will do! When I set them originally last year it seemed like I had to turn them up pretty high to get to the target voltage (28.3 for 200W/4ohms). I didn't have the bike on at the time so I backed them off a bit from that set point but perhaps not enough. Easter ran late so I'll try to get to it today. Since I have an AX-7000 which is not waterproof, I also have somewhat of a shroud draped over the whole thing to keep water off. Not wrapped tightly, just draped over the entire amp tray area so that water will hit it and hopefully run off. Wondering if that's trapping heat, but will start with the gains, with the bike running .

Thanks! I'm also wondering if I should while I'm in there, connect the left and right side in parallel (upper left, lower left/upper right, lower right) which would give me a lot more power to all 4 speakers. The only downside I can see is that I loose the ability to tune the lowers separate from the fairing speakers, but not sure if that's a huge downside or not.

200 watts is enough to have those GZ's sounding good, loud, and clear.
