I installed Hella Red Grills on my Innova when one of the original horns packed up. Very happy with the sound. Its loud without being irritating. The horns look like red fangs through the Innova's grill😀.

I do not know what horns come fitted as stock on Mahindra vehicles but if your stock horns consume less current than the red grills, install a relay. See below the current draw for some aftermarket horns. All values are for a single piece, not pair.

Hella Supertone Red Grill: 5.5 Amps
Hella Spice Tone: 3.5 Amps
Roots Vibrosonic: 4 Amps
Roots Megasonic: 4 Amps
Roots Windtone: 5 Amps

Yes, that is right. The smaller Hella Supertone draws more current than the larger and louder Roots Megasonic.

refer my earlier post.
last week at MMASS, asked them to check the horn also. Generally I stay next to vehicle, watching the works. I was maybe away for sometime, and engineer had already replaced with a new horn!

He said, the "high tone" piece was faulty. In Xylo, there are two horns installed (OE Hella), "low tone" and "high tone". if both working together, then mixed sound will be good! which means the original "low tone" is still intact, running.

I checked the new setup - the sound tone overall has changed from the original, but this is good note. its pretty loud as well, better than earlier. Im happy. Cost incurred = 500 (horn & labour). Not bad.

for ref, some pics of old horn and box pics:

Hella Supertone in My Swift - Mounted a pair on the front beam in such a way that they are visible through the radiator grill but as I anticipated they would barely show because of the angle and thickness of the slats.

Sound is good enough, louder than stock. About as loud as the Hella Spice Tone. The changes can be reversed without much issue as no cutting and taping of the stock electricals was done. The stock low tone horn of still connected so the stock wiring powers that and the relay coil only. The wire from the battery to the relay is a fuse wire cum box that seems to have 3-4 sq mm cross section. Relay to nearby horn is 6 sq mm and from near to far is 4 sq mm. Wires from stock wiring to relay are 1.5 sq mm.

Mounting strips are thick ones that are used to mount plastic boxes on Splendour and other such bikes. Used without modification. DIY installation time was 4 hours because I had to go to multiple places to get the strips, male spade connectors and nuts, bolts and washers.

The redgrills on my 2WD VLx were acting funny. Wasn't sure if there is an issue of rats biting the wires or the horns acting up.

Got it inspected from the competent electrician, he opened them up, did a bit of cleaning and voila, it was back to its irritating best

The one on the 4WD S10 is working fine.

If the hunger to find the loudest horns for Indian roads is not over.
Try these Loud horns; and I mean loud as in

1: http://www.amazon.com/BEHEMOTH-Tripl...ds=train+horns

2: http://www.amazon.com/Stebel-Nautilu...K9T8ZF88MQ22ZT

The Behemoth (1) comes with a Seven trumpet set as well with 210 dB sound (claimed).
However the second one, Stebel Nautilus is an ear breaker on its own.

Regards,
Saurabh.

Finally managed to fit a pair of Megasonics in the front bumper! They're loud and I love it!

Guys I want to replace the stock horn in my punto to the Skoda/Merc/BMW type horn. I'm confused between the Roots Windtone and Minda Trumpets. Had a few queries:

1. Are both horns waterproof?
2. Which is more reliable of the two?
3. Which one sounds better?
4. Do I need to install a relay cutout too?

I'm planning to get them replaced tomorrow, so a quick response would be much appreciated!

Nop, NONE of the trumpet horns are waterproof. The trick is to fix it in a place which can keep it away from water (preferably engine bay).

Reliability of these horns are pretty much the same; these can't be repaired either. I haven't used Minda, but from among Roots and Hella (Twin tone), I prefer Hella more as it's louder. Roots Windtone is softer comparatively.

If your current horn is powerful and comes with a relay, you don't have to install it. For Windtone in a Wagon R & Hella Twin tone in a Swift, no relays were used.

Minda trumpets. I got them in my City and trust me they sound even better than the Skoda Oem horns. Also they are quite reliable. No need of the relay.

Thanks for the inputs! Will probably go for Minda cause I came across it on youtube and the sound is perfect for me.

Also, can I use the stock Punto horn in my Fabia? Fabia comes with a single trumpet horn whereas the Punto's are double(non trumpet). Is it an easy install or will I have to make do with only one of the horns and keep the other one as spare

Need some advice :

I have changed to some local horns, which look similar to Roots Megasonic (because of chrome grill on disc type horn), in my Swift which are rated at 6A. I have done a simple plug-n-play for the install and didn't add relay/better wiring.

How much are the stock horns rated at? I have the horns with me but the power specs aren't mentioned anywhere.

Do I need a relay? How can I add one without cutting stock wiring? When I fitted new horns, stock locations were far apart for low and high tone (top left of grill and bottom right of airdam) and wiring a relay would have meant joining the 2 positive wires of stock horn, which isn't possible without removing bumper entirely or maybe not possible at all as stock wires do not have much flexibility (as they are far apart).

Which relay would I need in this case? 4pin 30Amp one?

I am not facing any problems now but I think a relay will make them sound much better. The ones which I have changed to are 1-1.5 cm bigger in diameter than stock.

If you have dual horns in the Swift, then the relay probably is already there. When I added the new horns, I was told there is no need to add a relay as it's already available.

Yes, two horns are stock and a relay would be present already.

The stock horns in my '15 Swift were a pair of small sized Hella units. Not sure what their current draw is but when I installed the Hella Supertone (Red Grill) I installed a relay and 6 sq mm wires. Current draw of those is 5.5-6 Amps each. I don't think the stock horns draw that much. Had you bought genuine Megasonic horns you would not have needed a relay since they only draw 4 Amps each. To be safe I suggest you add a relay. My post about this installation is probably on the previous page.
