shutdown/overheating

[4lowrodeo 10+ year member]

after playing for an extended time period my amp is overheating and shutting off on me. I have 8 guage wiring ran about 14' to a 500 watt amp. this is a little underpowering, but could this be my reason for overheating?

if anything that would probably prevent your amp from getting enough power, therefore, causing it to not have a chance to overheat. what amp and subs do you have (brand, model, specs) and how do you have it wired up?

phoenix gold xs2500 amp running one Eclipse 88120.4 and I have it bridged for the one sub.

i could not find the specs on the PG amp but the subs ohm rating is 3.1ohms. if you are bridging the amp into that load of 3.1ohms it is seeing about a 1.55ohm load. your amp is probably not bridgable into that ohm load. most are only bridgable into a 4 ohm load. check your specs on the amp and make sure your gain is not set to high.

also might see about upgrading to 4 gauge wire....14ft of 8 gauge wire for an amp over 500 watts.....i wouldnt recomend it....

i believe the amp is 4-ohm bridged. do I have this wired up wrong? and is the gain the sensitivity dial on the amp? I have one nob that is "bass" and one that is "sens" that what youre talking about?

I know the wiring is a problem, but I might upgrade and add another amp in the future and just use the PG for components. so when I do the upgrade Ill run 1/0 guage...

thanks for the help guys.

well at least you are aware of several minor problems which can be fixed fairly easily.
