amplifier problem

no didnt do that, guess ill get a volt meter tomorrow. now the shop used a voltmeter, at least i think it was a voltmeter, to check the remote wire when i was thinking along those lines. it did show no voltage then, but my other amp is working off the same wire and doin fine. so hmmmmroflanna

I went through the same thing with a hifonics amp for my subs.  Was very tempermental,  Tried everything.  Took it out to hear something loose inside.  Took it apart only to find a couple things burned up.  I have a feeling your amp is on it's way out.  And you prob won't be able to spot it till it is toasted.  May as well pull the amp apart and poke around though.  beware of brown!!

ok, ill bite, whats brown??roflanna

Burnt

When the shop used the meter and determined you had no voltage on the remote wire, did you notice where they had the negative lead of the meter connected?   Was it to the ground terminal of the amp or was it to the chassis of the vehicle? 

A shot in the dark, internal power supply caps? if one or more were dried up or very high resistance it would cause odd results and wouldn't pop the fuse. No unusual noises, no excessive heat and the results change with time. Ask the tech if the caps were replaced. Look to see if any are swollen or split. Good Luck!

well i give up, time for a new one i guess. i should be happy, i got almost 6 years out of it, lol... ok, just a good, strong, 4 channel amp to push 4- 6.5, 2ohm infinity door speakers for about $100, just till i can get that big memphis 5 channel 1300 i want. any suggestions. thanks for all the advice by the wayroflanna
