5.0 out of 5 starsPerfect horn for my application! Great low tone.
By J. McCune on February 2, 2011
Color: Black
Length: 0:50 Mins
I'm really happy with this purchase. The stock horn in my 1990 Suzuki Samurai sounded weak and wimpy. I wanted a horn with a nice deep tone that wasn't so loud that it created accidents or fist fights. Most horns that I heard on the Wolo website were far too high pitched but the sound of the 320-2T is exactly what I wanted. However, these horns are not small so you may need to create room to make them fit. Luckily, I had plenty of room next to the radiator and there was an unused bolt on the chassis so I didn't have to drill any holes. I stacked them on top of each other, mounted on the same bolt, and both horns pointed directly through the grille. I couldn't imagine fitting these things in my old '88 Accord. I also had a positive and a negative wire running to my old horn so to install the 320-2T, I had to create two Y connections with spare wire that I had. Even if you have one wire to your horn, it will take a little bit of 'know how' and elbow grease to install these horns. Directions for both styles of wiring are included. The whole install took me about 45 minutes and I thought I had it easy. But now that the horns are in, I'm very happy with the results. It's not overpowering but it's a nice, healthy, baritone blast. For my application, it's exactly what I was looking for.

PROS: Great deep harmonized sound. Inexpensive.

Potential CONS: Require a lot of room to install. Installing two horns is trickier than one.

I have a Dodge Sprinter. A huge van with a wimpy horn that nobody hears.
Replaced the horn with these, and it is a BIG difference!
Installed in about 20 minutes.

Here's a comparison of the old horn:

5.0 out of 5 starsgood solid sound
By Patrick Madigan on March 21, 2008
Color: Black Verified Purchase
I put these in my Mazda 3, and now the car has a horn that I'm not too embarassed to use. These horns sound great, reminding me of the classic horn sound that you'd get from a 60's/70's car. They would have been easy to install if not for Mazda deciding to bury the factory (single) horn in a ridiculous location... actually had to remove a wheel to get at it! And of course, if you are replacing one horn with two, that means a little wiring is needed, but it's not too bad. Just mentioning this in case you think that swapping a horn is always a complete no-brainer... sometimes yes, sometimes no.

5.0 out of 5 starsToyota Tundra fix
By B. STARK on December 13, 2008
Color: Black Verified Purchase
The Japanese have no idea on what a good horn is. At least the rest of the vehicle is excellent. The truck no longer sounds like Herbie the love bug, how embarrassing is that for a full size truck. It now sounds like a good classic horn should, slightly annoying and probably 30-50% louder than the Japanese stock junk. Seriously the single horns on my motorcycles were louder and better than stock horns on this truck.

Install took 10-15 minutes and requires a 10mm and 12mm socket. Use both pieces of metal flange so it is stiff enough to prevent the horn from moving (same as stock). Comes with all hardware you will need if you have a standard twin horn stock installation. They are almost twice as deep as the OEM horns. On the truck there was room but it might be an issue on a smaller vehicle. The horns have a standard tab style electrical connectors so they should hook directly to stock wiring connectors. Toyota's connector is a bit wide so I just bent all the tabs 90 degrees and it connects fine. The silver screens shown on the picture are junk practically fall off so I just took them off before they rust out anyway. The connectors are brass and overall the rest of the horn looks like decent quality and worth the price.

1.0 out of 5 starsAWFUL!!!! Suck so bad
By nate on December 15, 2012
Color: Black Verified Purchase
AFTER 2 MONTHS OF USE:
I installed these on my 87 Toyota truck and they honestly worked for 2 days and then stopped working! I would tweak the screw and they would work but for only about 2 minuets! They drove me crazy! So I went to the junk yard and got a fiamm horn from an old suburban and they work and sound amazing! ( the suburban is about 6 years old so the horn is that old) Wolo horns suck go and get a set of FIAMM!

4.0 out of 5 starsMuch better than "meep meep"
By SW Engineer on May 4, 2009
Color: Black Verified Purchase
I bought a 2009 Pontiac Vibe about 6 months ago. The base model comes with a single "meep" horn that sounds like an apology. I wanted something a bit more forceful. At first I was looking a the Wolo Bad Boy Dual Tone Air Horn. I put a similar type horn on my motorcyle some years ago and found it to be very effective at getting driver's attention. Then I read a review from someone in Toronto who installed a Bad Boy and liked it except for the fact that the compressor froze up sometimes in the winter. I live near Detroit, so I ruled out the Bad Boy. These horns (320-2T) sound like the horns on the Buicks my Dad had in the 60's. They're not the loudest I've ever heard, but still much better than a single "meep meep". Installation wasn't too bad on the Vibe. Now it's just a matter of seeing how well they hold up over time.

5.0 out of 5 starsHad to get creative w/ the wiring, no slicing & dicing just used the jumpers
By J-Dawg on August 15, 2012
Color: Chrome Verified Purchase
Had to get creative w/ the wiring, no slicing & dicing just used the jumpers. The 2 diagrams provided for the wiring did match my configuration but I just used the provided jumpers to complete the circuit w/o having to cut my OEM wires this is good to do in case you ever have electrical issues you can return it to stock before bringing it in for warranty work. This is installed on a nissan juke so if u need assistance (w/ juke install) comment on this w/ your email and I will send the new schematic I made, it's really simple.
