Review on Hella Stark Sound - Red Set 12V H/L Frequency Hella Super Tone Horn Set B 133, 12 volt by Matt Jenkins

An exceptionally loud upgrade over my factory base 2020 Legacy. It comes in a box with two horns and a relay. This is a 300Hz horn and a 500Hz horn. Each has a small bracket screwed on that fits perfectly into my car's existing radiator bracket. You don't need correct polarity to make a connection as the audio works with positive and negative tuning using either terminal as long as one is positive and the other negative. It is important to note that each of them draws about 6 amps and together 12 amps. So you need a 15A fuse to power your horn relays. I tried a 7.5 amp fuse which blew after a 5 second siren blast. Very easy to install but requires some engineering skill to place, ground and wire the relay via the factory horn input.
