Unimpressed with your factory Hertz system? The Hertz Venezia V4 and V5C amps in Yamaha boats weren't properly tuned before the boats left the factory, so most have never sounded the way they should. In our experience, the factory settings only use about 10-15% of their output potential.
How Send-Tune-Send works: ship us your amps, we tune them on the bench to their rated output with professional tools (no guessing, no tuning by ear), and we send them back ready to install.
Tuning by ear can push a system into distortion and clipping, and that's how amps and speakers get damaged. Get it done now and you're set for day one next season.
$100 per amplifier, plus return shipping (calculated at checkout). Choose your amp model and set the quantity to the number of amps you're sending. After you order, we'll email you instructions for shipping your amps to us. Questions first? Contact us.
