Yelled...literally YELLED at me for doubting his work. He gets "offended when people ask him to double check his work" and needed a prepayment to take a look and see what might be wrong. Took it to the dealer prior and they told me they couldn't help and go back to the after market install guy. Idk why he yelled at me that the camera HE INSTALLED stopped working. What good is a 1 year warranty if you're gonna make me pay again anyways? Ps - dealer charged me $0 to take a look. Poor customer service and treatment. Would not reccomend. In reply to Bruce - I was hoping my 2nd guy was the kind of guy to fix it. Jokes on me. Thanks for the extra electrical tape!

I met these guys at Wisconsin Harley Davidson during the 2018 Milwaukee H-D Rally over Labor Day…read more They installed a Rockford Fosgate TM400X4ad Amplifier and Rockford Fosgate speakers on my 2017 Road Glide. At the time I questioned the use of "Velcro" as an install method for the amp. They told me it was the only way to do the install and make it fit. This week I took the inner faring off to have it painted and noticed the windshield was cracked at the base by the mounting screws. It would be hard to prove in court but I did see them use a drill driver to put the screws back in and I am sure that did not do my windshield any good. I also noticed the amp had fallen of the Velcro and was a little banged up. That explains the rattle I was hearing. After the initial install, I ended up asking for all the extra parts from the kit. They did not use the heatsink or mounting bracket for the Amp. This is a 400 Watt amp and I believe the engineers at Rockford Fosgate included a heatsink because it needs a heatsink. It is a good thing I saved this stuff. After watching a 15 minute you-tube video by Rockford Fosgate on how to properly install this, I reinstalled it correctly myself. It took about 30 minutes. I also noticed that they ran the power wiring over the gas tank rather than lift the tank to rout the wires properly in the factory H-D wire tray. I need to fix that next. I am sure these short cuts saved time but the result was a very crappy install. And let me point out they charged me plenty for that install. I have found no fault with the Amp and speakers, they are a big improvement over the stock Harley amp and speakers. One last tip, the Rockford Fosgate instructions tell you to set the amp to hi pass (this will limit the base). I believe they may be trying to prevent speaker failure. When I reinstalled mine I set the amp to "All Pass" and WOW!! did that wake up the system. It sounds awesome now. The guys at Extreme audio seem knowledgeable and were very nice, but they are taking shortcuts that they simply shouldn't take. They would do well to follow the Rockford Fosgate installation instructions. Contrary to what they said, everything fits just fine under the faring when installed per the instructions. If you have them work on your bike, tell them to skip the Velcro and do it right! Good Luck.

I explained what I wanted and how I wanted it to look. But I later realized I forgot to explain a key detail. Fortunately that detail was not overlooked by the staff. They did exactly what I had wanted anyway. The work was done better than how I explained it and the results exceeded my expectations. I expected to pay more than I did. I am very happy with the quality of the work and with the knowledge and how friendly the staff is. I'll be back for another project later this month. I made it to Extreme Audio for that second project and they did another great job with it. Very impressed. So what do I do? I go ahead and cut a wire by accident. Fortunately I realized what I had done and they fixed it for me no charge. Great service, very helpful and I am very pleased they are around!
