You are not going to regret changing out that amp. I was hesitant to replace the 2 PBRs on my bike. Huge difference going to the Stinger 700 and the NVX Vadm 4 that replaced my PBRs. I also replaced my Kappa's with the Mmats 601.cx. another great upgrade while you are in there.
Surprised you are having harness issues though. I had no issues with my PBRs over the 2 years I had them. Had one sitting on the Sony HU, and the other one on a hogtunes amp bracket.

 

Massive BLX4 is on sale for $149, down from $399

Definitely Overkill on the Kappas, but would sure be a great choice if he had any thoughts of future upgrades at that price, if anything like lowers are a thought.
4 x 175 watts at 2 ohm would be plenty for 4 Kappas or the 4 x 100 watts at 4 Ohm definitely allows for more speaker options down the road.

If he is set on just the 2 speakers, the NVX Vadm 2 dialed down a bit from the 200 x 2 at 2 ohm for the Kappas or 150 x 2 at 4 Ohm for a future fairing speaker upgrade looks not bad, but still falls pretty close to the price of the Stinger 700.

 

Where you see that? 229 is the price that comes up for me.

The Stinger price went back up within an hour after I ordered one at 6:30am this morning.

 

Dang! Late to the party once again.
