I have a 2010 AT GE8 and want to replace the wimpy horn with a set of SickSpeed horns (dual tone like Hella). I bought the horns and have my wire and solder gun ready but my question is can I pull directly off of the stock + wire (purple) for power or will I need to include a relay?

Don't want to fry my stock wiring but at the same time doesn't seem like they draw much amperage.

 

Usually they say to use a relay. The real Hellas come w it. There are a lot of threads (not necessarily on ff) about the install. Link how these sound! I almost pulled the trigger on a set today, but with only $15 between these and the Hellas I'm still torn.

 

I need to find out how to wire the relay and what kind I need. I have wire and a soldering gun, just need the rest of the stuff. Oh well, another day.

These things are freaking loud. Sound just like Hella supertones to me.

 

Where are you mounting them? I am thinking about these as well. I had PIAA dual tones on my Tundra and really liked them.

 

Stock mounting point in front of the radiator as usual.

 

I've used the PIAA horns which look to be about the same thing and I didn't use a relay, it worked fine. It's probably better if you do, but I don't think it's a requirement. My car didn't burn down.

I just used the stock horn wiring.

 

Where can I buy a relay for my super tones? I have sickspeed horns but I have no relay or wiring. Is it possible to just wire it and everything all stock wiring? If not where can I buy the supplies needed. and what are they?

Relay Wiring

The "Switch" is your horn button. You can pick up one of those relays at RadioShack for a couple bucks.
