    • Sound Improvement
If you have a bagger, this kit will work and not take up too much room. If your bagger has a stock amp, the kit has enough wire and information to allow you to use much of your existing wiring without too much cutting. My only complaint is that when it connects to your phone, the announcement tone blows your ears out. Bottom line is that my harley stereo kicks butt (also upgraded speakers) over the stock boom system. Highly recommend this amp. Tech support via phone was also great. ... show more

    • Needs to be complete or would be 5 star
Why did you pick this product vs others?: Missing the wire for the left bag luckily I contacted the manufacturer they gave me one but this kit should have it took to long to return not it’s my problem but other than that good kit just my bad luck I guess

    • Almost perfect kit
Watch the video. It’s a simple install. Quality water proof connections. Wired nicely. Two problems. It’s ridiculous that they do not include the inner left bag speaker wire to connect to the plug at the grommet. It’s a $70 accessory or ya just make your own. Either way it’s ridiculous that ya pay this much for a very nice harness but Rockford Cheap’s out and doesn’t include the inner bag harness for the left side. Charge an extra $5 for the kit!!! The other thing is each time ya turn on the bike be ready for an extremely loud beep While the blue tooth connects. Both concerns are relatively minor. Clean kit ... show more

    • Good but could be better
This wiring kit make every so easy to install. Make Sure you check before you cut the holes, I had a bar running though where the template said to cut 🤬. So I had to figure out where it would actually work. Right side speaker keeps going out. Had a break in the wire or something after only 2 days. Then it quit working again about a week later. Rockford Fosgate is sending a replacement, but not the point. Also if you don’t get the speaker kit for the bags you’ll be missing the connection to hook of the left speaker, I had to make my own. Called Rockford Fosgate and they stated that they don’t have any so they will not send one. I’m sorry but for $270 I should not have to make my own! But overall it was definitely a good purchase, as long as the wining issue gets fixed ... show more
