I already have two DIYMA12 subs that are 5ohm each. These subs have gotten great reviews and more importantly I already own them.
I can either run them at 10 ohms or 2.5ohms. Maybe 150 watts per speaker would be fine, I really don't know. I don't listen to music very loud. Do you think 150 watts per subs would be sufficient?
My other choice I guess would be to make the amp staple into 2.5 ohms, but from reading a previous thread that seems to be running on the hairy edge. I guess could run a squirrel cage fan to keep the amp cool.
Sometimes, the shrink wrap on the electrolytics will split and fall off when the cap overheats. If no electrolyte has leaked, the cap is probably OK.
If you do any work on the amp, you may want to replace the large electrolytics. Most are probably still within tolerance but I've seen several older orion amps that had rail caps short and destroy the power supplies. They were black. I've never seen the brown or yellow caps short.
You'll need a good soldering iron and lots of patience to change them without damaging the board.
The amp has four large dark blue 3300ìF50v and two smaller light blue16V3300ìF capacitors. One of the light blue capacitors has the shrink split off. None of the capacitors is leaking. I didn't see any large black capacitors. Should I be concerned about these or assume everything is working properly?
