Hella Help

So i just got my new hella supertones and cant seem to wire them up correctly. i have the Subimods relay. I plugged into the innermost horn with the male part. Then i just put on the relay. ground the 2 grounds and plug in the horns.

 

i push on the wheel and nothing. I hear a little click like it wants to work but no luck.

 

any help??

There arent two grounds. One goes to the battery

whoops. that would explain it. hahaha

You get them working?

I did. and let me tell you.... these suckers are LOUD!!!!. i like it.

Pfft 2. That's nothin.

 

I have 6.

6?!?!?!?! you trying to make those poor people in front of you deaf??? hahahah

Did you take yer front bumper off to install them?

nope just took out the airbox. Its pretty easy if your leaving the stock horns in there. Just unplug em and plug in your harness. :-) nice and easy

Sweeeeeeet...thanks for the head's up.

Do all installs need the harness/relay?

 

Did you get the bracket from subimods as well, was it worth it?

i used the bracket and the relay. on black friday the bracket was free with the horns. I like it. Puts the horns right up there. The relay worked pretty well with the harness but isnt needed. You can easily make your own harness.

Harness isn't necessary if you have any kind of electrical experience. I just did mine yesterday and didn't have any trouble. I just followed the install chart that I found here on a search.

 

Just get a bunch of these to fit onto the posts of the relay and the horns and some wire and you're good to go.

i didnt use a relay and theyve been working fine....

 

are there any drawbacks for not using a relay?

I used a relay because I wanted the horns to be able to draw as much current as they can. They are plenty loud.

The relay doesn't amplify the horns. The stock horns run through the same 12v current like the hella tones. I have heard other with hellas horn with the relay and they sound just as loud as mine.

Incorrect.

 

Voltage and current are very different things. Thin wire has higher resistance when trying to flow high current. 18 gauge wire has 4 times the resistance of 12 gauge wire.

 

Higher current means louder horns. Through wire, higher current means higher temperatures, and resistance is the enemy. My horn wiring runs cooler, and is more efficient, than using the stock wiring. Plus, if something were to go wrong, the horn circuit is completely independent of the cars circuit (save a single wire, used to trigger the relay).

 

A while back, I back-fed checked the voltage and current drop for the headlight harness on my old Forester. The difference between the aftermarket harness I built and the stock wiring was substantial.

OoooOo. Interesting.
