a2-300 no longer working
There was loud popping from subwoofer. I tried to slowly lower the crossover (originally set at 180 max). LED light turned off. Nothing coming from subwoofer. Tried to power off and power on, nothing. Unplugged the power supply. Checked fuse, blown. Replaced fuse. When signal received, light turns green for a second then immediately shuts off. Checked fuse, blown.
Removed plate amp and driver. Tested driver with 9 volt battery. Think I heard a knock. Tested driver with multimeter. Got 3.7 ohms from each side. Is the driver good? Visually inspected amp and I think it looks okay. Are there ways for me to check if the amp is the problem?
I think I may replace driver even if it still good. I believe the current driver is the e3.12. Is it any good? Thinking about replacing it with Dayton Audio RSS315HF-4. Any better recommendations?
As for the amp, I read about sending the amp to be repaired, but before I did so, I wanted to be sure that was the problem.
Not sure where to go from here. I don't want to invest too much money in the subwoofer at the moment.
Can I assume the driver is still good and the amp is the problem? Should I hook the driver up directly to the receiver to test the driver or is that bad for the receiver? Should I test the amp with a bookshelf speaker or would that put the speaker at risk? Any other ways i can test the amp?
Or should I just get a new sub? If so, should I get two ~$200 subs or one SVS PB-1000?
Bottom line is I need a sub. I don't want to spend money if not needed at the moment. Would love to try to repair it myself. I'm not knowledgeable with audio repair, but I'll try anything so long as I'm not risking my life. Thanks for any help.
Receiver is Denon 3808-CI, if that matters any.
