Yes,  a bad ground can be the culprit of a hot amp,  but there are other factors at play too. What pre amp voltage are they feeding it? There's a wide range available from 2 to 8 volts. I know they go higher but those are typical. At what ohm? 1 will cause the amp to heat faster than 4. There are alot more variables than a poor ground to consider. How big is the ground wire from the battery to the chassis? If it's 4 gauge factory wire, considering you don't have a second battery, and you have a 0 guage amp ground, you're not doing much better. All this is just another reason I like a second dedicated battery that's up to the task.Sent from my Nexus 6 using Tapatalk</blockquote>
