Best stereo upgrade options

[ths61]

...

I have a pair of Premium Polk MM 651 speakers, but can't yet get myself to modify them to fit. They have a wider basket and require a spacer to fit the magnet, which is provided.They will also not allow the shelter- speaker cover to snap back on tight, so that will require some trimming. If I go there?

...

Do you know if you could get by with a thinner spacer (to seat the speaker deeper) ?

Not sure which speakers you are thinking about but the opening in the dash is just under 2 1/2" deep so most all speakers except the MM will fit for mount depth. The MM measure 2 5/8" so at least an 1/8" spacer is needed. If you select a " shallow mount" speaker, be advised you give away capacity with most speakers. RMS and Peak wattage because of the smaller, shallow magnet. Don't know if this helps.
Good luck

Thanks, you answered my question.

I was referring to the MM651 from your quote that I posted (updated quote in red). From pictures of the MM651 spacers that I have seen on a Goldwing install, they are a lot thicker than 1/8" so it sounds like the speakers could be seated closer with a 1/8" spacer which should help with the dash cover clearance issue.

I am happy with the stock speakers when riding without traffic, but in traffic or with loud pipes, the stock speakers just don't cut it.

The guy who did the Goldwing install used the stock speakers as a template to cut the MM651's and their spacers. This appears to have taken off a lot more meat than what was necessary. A template could probably be made which just accounts for the minimum amount of material to be removed which should help preserve the structural integrity of the speaker.

Hmmm.
My DXI 651 speakers sound great, but I have a pair of MM651 that are just screaming to me the amp needs us... These pictures are making me feel better about cutting them to fit. My amp is 100 watts + certified RMS and so are the MM. The DXI are rated at 80 and though are capable of playing very loud, I can push them too hard. Sounds like I'm justifying...
Anyway, good luck to all who have led us down this path and those just going.
Ride hard but wear a helmet.

While on my Yellowstone trip I had a chance to catch a listen to a friends stereo on his Streat Glide I think, newer Harley anyway, and it sounded soooo much better than mine. I will do some type of stereo upgrade this winter.

I'm starting over with this post. I have the MM6501 not the MM651. I didn't even realize there was a difference. I'm looking up specs now to see if they are the same dimensions. I also blew up the photos THS61 posted. I was on my mobile and didn't realize what was posted. I'll keep you posted, unless anyone has info on the 6501 mounting

You still have to trim the basket to mount a 6.5" speaker, regardless of who makes them.
