I have 4 power acoustic d3000.d1 when i first got them i had them in a box with fans.The internal fans quit working and started me on a quest of replaceing caps mofets.i had all working exept 2 of the amps kept poping caps. I found out later that i got bad caps.Now i replace them and all has been good.2 months down the line 2 of the amps started makeing niose that you can hear at low or no volume.The nioce dont wine with alt and after the amps been on for a while it gets quiet but still can hear the amps are strap and dont get hot. i was going to replace the caps that have been giving me trouble but have this feeling there the wrong ones.could they be the caps that are next to where the speakers connect there are 4. The caps i have been replaceing are the 6 after the toriod.The interenal fans quit working because i had them standing up now they are flat.
