QUESTION: Hi,
I Originally purchased twin subs and connected to a mono amp. At the time my other 4 speakers were stock. I now want to connect a 4 channel amp to 4 after market speakers. How do I go about doing this?

Answer
Hi Jeremy,

It not certain that you did anything wrong at all.  Unless you somehow connected a 12v power wire to a speaker (not likely), the problem is most likely a defect in the speaker or the amplifier. Sometimes an internal fault will cause an amplifier to produce a relatively high DC voltage on a speaker output.  You can test for this with a digital multimeter.  It's also possible that the speaker itself had an internal short.  It's likely that you'll need to replace the speaker, but I'd double-check your wiring and test the amplifier's output for DC voltage before connecting it to a new speaker.

Hope this helps!
