Way back in this thread somewhere (or possibly a different thread)) I spoke about how we have tested the new 7.25s with the Arc Audio Mini amp, running at max volume before distortion for a total of 60+ hours ,,,,,, with no failures of any kind either with the amp or the speakers during the test ,,,
at the conclusion, the speakers still performed like new and so did the amp ,,,,, the Arc mini amp is rated at 125 watts RMS into a 2 ohm load ,,,,
Biketronics also offers very good amps ,,,, and we are testing their small one now ,,,,
but at some point as these amps get more and more powerful, J&M will have to design an alternate 7.25" speaker to handle very high power levels ,,,,
no doubt the J&M 7.25s and the new rear 5.25s are THE BEST performing speakers for the stock Harley audio system period ,,,, they are also THE BEST performing speakers for your Harley even if you add an amp ,,,,, that simple ,,,,
but I would not use an amp rated at more than 125 watts RMS per channel with them ,,,, now before you go comparison shopping for an amp all over the internet,,,,,,, check the RMS (((not max)) power ratings of each amplifier into a 2 ohm load (((not 4 ohm)) ,,, that way you will be comparing apples to apples ,,,,,
