You will notice some difference, but without an amp too, I wouldn't make the change. Either leave stock or replace with speakers AND an amp. I went with Biketronics Titan II 7.1s and then their BT2180 amp. The combo is awesome. Can't say enough...

 

YES--go w/J&M

 

I replaced my factory speakers with Biketronics 7.1's and then switched out the rear speakers for Kicker KSC67's. I still wasn't done and added a SS 4.520 amp and topped it off with a Kenwood X998 HU. Now, I can hear my tunes at 80 MPH on the highway. It wasn't cheap but it wasnt super expensive either...

 

did the hogtune speakers...a little less distortion but not much

 

Looks like the biketronics amp and 7.1 speakers are popular. $650.00 is expensive but I hope it's worth it. Not going to change the head unit yet. If you guys say the upgrade is like night and day I believe it.

 

It is - you won't be disappointed with that combo. I get good sound at 80 mph with ThunderHeaders. It's day and night over stock. Just to let you know, I tried it with just the BT Titan II 7.1s speaker change at first. It was better, but you can tell that with an amp it would make a HUGE difference - and it does. I talked to the folks at Biketronics who are great to deal with. They said the same thing.... you can change the speakers alone, but it will leave you wanting more. They were right along with the folks in the audio forum. The weak link now is the head unit. They like to distort really early compared to aftermarket head units. I just didn't want to loose my CB and intercom at this time so I still have the stock H/U and it works OK for my needs at this time.

 

Theres a small noticeable difference. The only mod my bike had when I bought it was the fairing speakers were upgraded to J&M's. My buddy has stock speakers in his SG and mine are slightly louder and clearer. I'm adding tour pak speakers so I'm going to add an amp.

 

After a lot of research I am thinking about going with the hang wired direct connection system that comes with the 5.25 speakers and amp. Hopefully this is worth the added cost

 

In a word...........YES
