Amplifier outputting less power over time taramp15k

Recommended Posts

When I first metered my 2 15k I did a 155.5. One amp got popped due to turning on with no load. So we hooked up just one and did a 154.7  I noticed a few shows later it dropped and did a 153.5. When we got second amp back from repair and to install it the older amp clipped out much earlier when setting it and all it did was get me back to a 154.7. I also left out the fact the older amp has a melted ground and blown volt meter from a bad ground job n past install. Is it possible some of the internal components fried n old amp making it not blow but just do less power? I’m running amps at 2 ohm each and they are powered by 6 northstar batts,3 singer alts and 8 power runs in a 09 tahoe on 4 zv5 15s.

Melted ground is a bad connection somewhere. You need to find that and fix it before you continue testing.

The hotter it is, the lower your batteries will float, the less output your alternators do, i.e. less power overall as well.

I always do my own audio work to avoid issues like that. I dont even let auto shops do any mechanical or maintanance stuff. I got a buddy who i have do the hard stuff and i do the easy shit.

Decided to just run the stronger 15k by itself it jams

but for some reason it’s remote randomly cuts on 4 channels when vehicle is off weaker 15k didn’t do that
