Turn-On Relay Kits

So you’re putting together an audio system in your vehicle that will use numerous amplifiers and signal processors. No problem. Our turn-on relay kits are designed to allow you to easily interface all of their turn-on circuits to your source unit.

Each Kit Features

  • The most reliable relay we know of: the venerable Tyco/Bosch 30 Amp unit.
  • Diode protection to prevent damaging the turn-on output of the source unit.
  • All hardware required to install it.
  • Step-by-step instructions.

Either kit can turn-on between five and six dozen amplifiers and/or signal processors.

Tony thanks, Fastest shipping ever! Your relay kit is awesome! I had a turn on noise from my mids/highs amp and now it’s gone since installing the kit! – Cory, Sanborn, NY
