Ok. Ordered the ss amp and four polk mm651... Looking at the specs for the pn4.520, I am not certain where/how to mount it. Do you have pictures of what you did?

 

you have a couple of options.

1.) a few members here are using 1/2" plywood, velcroing that to the headunit, then velcroing the amp to the plywood. Perfect height adjustment.

2.) you can do what I do my installs. Look here

 

UltraNutZ, thanks for all the help, i really appreciate it. it looks like the mm651 speakers will get here this week and the amp next week. Aside from the adapter rings, what else do i need to get? Should i get a High/Low converter like these ( )?

 

are you using the stock radio?

 

Yes. I guess I should have said that from the start.

 

you'll need either a 10ga or 8ga amp kit. No need for the line level adapter. Look in the Sticky section at the top of the audio forum. I just put this morning a bunch of step by step instructions. Use the 3rd one up from the bottom, 2012 FLHTK; same setup as yours just newer and all directions and colors are exactly the same. That's about as easy as I can make it without actually doing it for you. :-)

 

you sir are a gentleman and a scholar. thank you for all the help. if you ever swing by Maryland let me know and i will buy you a beer...
