    Best Amp for Harley Davidson

    Posted by William J on 31st Jan 2019

    I have purchased several other amp and tried them, they all clipped and would cut out. After looking at this amp and doing my investigation online, i decided to try it. Wow, I've played this amp for several hours on a trip and it never cutout or faded. I will suggest this amp to anyone. just for the record, it's not hard on the stator.

    Awesome amp!!! My second one (on second bike) and I will buy no other-------Biketronics 4180 4 channel amp is the best that I've found, after extensive research and discussion with others. I installed one on a 2015 HD Ultra Limited (first time ever doing something like this) and it was pretty easy with their quick connect/plug and play harnesses. I ran 8 speakers (6, 6.5" and lid Biketronics 5x7s) and the volume and clarity was second to none!!! Turn it up half way for superb listening pleasure (concert sound) at 70 - 80 mph. No glitches, great bass and sonic properties. If you want to turn it up more than half way----you need to step away from the bike (extremely loud in a pleasing way)!!!! Now I have installed my current purchase (#2) on my 2018 HD Street Glide Special and again, due to Biketronics plug and play harnesses, installation was a breeze (a little different than the last) and I am running 4, 6.5" speakers Fairing and lowers and 4 6x9" speakers in the AdvanBlack dual 6x9 lids. The sound is full, clear and extremely loud. Passenger is extremely pleased with the sound of the rear speakers. Riding at any speed the amp has proved it's worth. Biketronics has the best customer service around!!! It is always an extreme pleasure talking with Mike and Donna. They are very polite, friendly and attentive to your needs and requests. Unsure about something (installation, harnesses needed, etc.)?, call them and you will be taken care of----they won't leave you hanging, ever!!! I am a completely satisfied customer for as long as I'm riding and customizing----I will not buy another Motorcycle amp, because there is no comparison with the power, number of speakers run, ease of installation, and personalized customer service---Biketronics, the best of the best!!! Thanks for the concert on my bike--Rock has never sounded better!

    When i first added upgraded audio to my 15 RG i went with BT and loved it. Recently added 6x9 lid speakers and upgraded to a 4ch amp from BT as well. Compact, powerful and powers 6 hertz speakers without breaking a sweat. Worth the $$$ and you cant beat the warranty and fantastic customer service!!

    Best amp bar none

    I blew a channel on the 300 watt HD amp and was looking for more power and 4 ohm rated amp! I reached and read many reviews and the finally bought the BT4180.14! This amp is awesome! Not only does the is rock the new polks I installed, but Biketronics customer support is far and above any I have ever worked with for any product ever! I recommend Biketronics products to everyon and anyone that ask about audio equipment!
