Hello everyone. First post here, but I have done a a lot of reading in the past. I am a old school audio guys from the 90's and we have built a system in my son's 1998 S-10 extended cab and I am having as issue with the AMP showing a "Short circuit on output or between output terminal to GND" per the monitor indicator.
The system is as follows. Apline ILX head unit, three Skar EVL-12 4ohm subs (wired at .67 pohms), custom box by Andrew Jones, D4Sound JP on mids and highs, Autotech engineering 320 amp alternator, Big 3 wiring, D4Sound Lithium for secondary battery, two runs of 1/0 power from battery to lithium, two feeds from lithium to power disto on amp board.
Originally, we had the Smart Base 3k and it was really not enough for the three 12's, so in the past couple weeks we upgraded to the Smart Bass 5K. We did not see this issue on the 3K. I went to set the gains in the new AMP and noticed that when we turn the system up (when everything is cool or not been playing the system) I can turn the volume on the headunit to about 90% and then set the gains accordingly. I will turn it down right past where it clips. Then the more we play the system I see it go into constant flashing of the "protect" (6 times in one second) and the manual says that is a short on the output. It is like the more we play it the more sensitive it gets and will constantly start reporting the short on the output. I am very confused on what is going on?
I thought it might be the bass knob going bad, but I am not sure. Could the base knob throw a dirty signal into the amp and cause this?
Any advise would be appreciated.
