07 Yaris Horn

[jcboy]

Hi ctscott, so can i just upgrade to,say,hella supertones or bosch horns (both with 2 horns, hi and lo) without having to wire a relay kit?

I mean,what specs do i look at during a horn purchase that will tell me to not just use the stock horn wiring?

Because i was thinking of just jumping the positive wire and grounding the new horn, and im not looking at changing the 10A fuse to a higher (IMO u wouldnt advise of either)

Yaris sedan owner here. Thanks!
