I am running 8 speakers (at 4 ohms) on my 2015 HD Ultra, including the awesome sounding BT457 5X7" SPEAKER and all are powered with the BT4180 amp. Mike and the crew have been awesome in helping me get this do it yourself project completed, including custom made wire-harnesses. The BT457 blends very well with the combination of Hertz Mille Pro uppers (front and rear 6.5") and the Harley lowers for liquid cooled Ultras (Made in China). The clarity and fullness is outstanding! With the BT4180, I have more than enough volume and power to spare. BT457 when run by itself, it was loud and proud, but when combined with the full package----The concert level sound and volume is second to none. My passengers have all commented on the difference in sound quality and fullness compared to running the Hertz by themselves-----Exceptionally good!!!! The Biketronics amp and 5x7 speakers was one of the best investments added to my bike. I am extremely happy with my purchase, installation (made easy), and customer service. I will come back for more-----Outstanding products!!!!
