So I put these J&M 7.25's in.

About a year ago I installed a set of the stock size J&M's. I think they were three way speakers. I like you ran them with out an amp and the stock head unit at the time. My experience was that they sounded very tinny. Volume levels were no where where I could listen to them at highway speed and the sound was really worse than stock. I returned them. John and his customer service folks were great and didn't blink when I said I wanted to return them. I am now using Harley boom audio speakers again without an amp but with a Sony Marine grade radio from Biketronics and love it. Great volume and base response and the sound is very customizable .
I'm afraid it's the speakers also with no amp.
I mean, how can so many people be so happy with these and I think they are pretty lacking?
I need some 6.5 titans to compare as a baseline sound.

I am no audio expert but I believe that running 2ohm speakers from a 4ohm head unit can fry the head unit. Might do a little more research and see what you can find. If you find you need an amp do some looking for the ELF amp. All specs I have seen it is very comprable to the ARC audio but at about half the price. I have all my stereo stuff just waiting to go in. Good luck hope this helps.
I called J&M and asked them specifically on this. They recommended the 2-ohm. They said the 8-ohm wouldn't work for squat with half the power.
2-ohm stable small amp should work fine but still.....pretty dinky speakers.

I have a Hawgwired which did cost more, I don't know how much the J&M amp is but I hear it's supposed to be good. To be honest with you I know rockford fosgate is coming out with a 300 watt $270 amp that I'm waiting to see the dimensions, if that will fit that's what I'm going to be changing to.

I know what you mean about the impedance difference. In the case of the Arc 125.2, they list it at both 2 ohm and 4 ohm impedance power ratings: 125W/channel @ 2 ohm; and, 70W/channel @ 4 ohm. It's generally believed that the J&M is a 125.2 clone and should be safe to operate with 4 ohm speakers, though J&M doesn't provide a spec with 4 ohm impedance as Arc does.
