I have j&m performance speakers with their 180watt amp and am very happy. Ultimately it's your choice, see if you can hear both before you put your money down. Only you will know what you like.
I'm surprised no one mentioned Arc Audio MPAK 4 or better yet 6.
J&m speakers are made/assembled in China IIRC. Best of luck with your choice
ARC amps are great amps.. their speakers leave a lot to be desired.
Side by side comparison of the ARC KS125.2 and the RF PBR300x2, you'd be hard pressed to tell the difference aside from independent speaker gain controls on the ARCs. All depends on what you want to spend.
Best combination (best bang for the buck) out there IMO is the PBR300x2 coupled with a pair of BT Titan II 7.1" as Pioneer74 pointed out.
Biketronics here as well. Replaced my Hogtunes speakers with them.
Same here I did not like the sound or the quality of Hog tunes at all. Very happy with the Biketronics setup and customer service. First rate equipment and packaging.
