  1. Best amp bar none 5 Star Review

    Posted by on 17th Sep 2017

    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!
