Hertz-Triton 4-channel Combo C-SQ80044-MPX1653


The Triton SQ80044 amplifier is a perfect addition to your sound system. The powerful 4-channel amp has a small footprint that's perfect for your bagger and when paired with a set of Hertz Coax speakers, this kit is a level up for your Harley.

The MPX 165.3 speaker set differs from other coax speakers on the market. A high output soft dome tweeter is built right into the center of the woofer magnet, accomplishing these essential things:

  • All sound originates from the same point for a much smoother transition between high and low frequencies.
  • It uses the woofer cone to complete a more significant horn flare, increasing the high-frequency output. The lower frequency limit of the tweeter is extended, allowing for bolder sound in the vocal range.
  • Locating the tweeter in the center of the woofer eliminates having to find a place to discover the tweeter on the bike's fairing.
