  1. Great Product! Worth the money! Review by Jara

    I bought the whole kit because I wanted a custom color besides the original red, and the option to have a nice plug and play install! First off it can take a very short time, the instruction manuals for each piece or extremely simple and to the point and help out a ton! Getting some zipties cost me $2 at Harbor Freights and now I have a super clean install on my Horns, which I custom ordered to be silver to offset the black and gray of the rest of the car! They are extremely loud which helps for warning people who plan on cutting you off on the highways/ walk out in front of you as you are driving down the street! I have recommended them to my friends and they have started to order their own horns with custom colors to give that extra little touch to their ride! (Posted on 9/2/14)

  2. Makes honking fun Review by Paul Houston

    Took my WRX horn from weak to HOLY CRAP. Seriously, one of the easiest ways to make your ride just a little bit more fun to drive. 5/5 stars. (Posted on 8/17/14)

  3. Awesome Purchase Review by Blayne

    Just installed these on my bugeye. Bought the mounting bracket and wirng harness too. Only complaint is, I couldn't get the mounting brackets off the horns, ended up stripping one of the bolts, so just mounted the mounting brackets to the subimods bracket. Still looks awesome and the sound is incredibly loud. I won't get run over by anymore SUVs that don't hear my horn when they change lanes on top of me.

    If I'd waited just a couple more days before buying them, the purple would have been out. Oh Well.

  4. Complete Change of look!! Review by Korey

    The Hella horns i bought with the bracket and harness. installation was a breeze and they look aggressive in the grill of my wrx!! will be ordering here again. THANKS SUBIMODS! (Posted on 8/7/14)

  5. Awesome! Review by Diego

    Great set with the harness and bracket. Very easy to install with and without the bumper! (Posted on 8/7/14)

  6. Cant be beat Review by Mike

    Subimods comes through big time. I wanted a set of these for the longest time but wasnt a fan of the colors they had available..they recently asked on facebook what colors people wanted to see, me and several others said green..sure enough within 3 weeks we had green horns available. Bought them two days later along with the wiring harness and mounting bracket and couldnt be happier..install instructions were clear and concise, product was top notch, and their service is outstanding..I will buy all of my aftermarket goodies from this company..keep up the good work!!!

  7. Subimod Hella Kit is great. Review by Steven

    The bracket and harness are worth every penny as once you get the bumper off, the horns are installed in about 20 minutes with no guess work at all. Plenty of slack for ease of installation.

    The harness was so good I ordered a second set of horns and the harness and installed them on my wife's Tacoma. Same exact setup and plug-and-play just like on my STi. (Posted on 8/4/14)

  8. MUST BUY Review by Chris

    Wish Hella didn't move to India, but these are still nice and loud. Just a different tone from the German ones is all. My second set installed on 4 cars now. Way better than any stock horn, and the look on people's faces when they hear it, then realize it came from you - priceless. (Posted on 7/24/14)

  9. Hella Supertones Kit Review by MrSunday

    Purchased the Subimods Hella Supertones kit with bracket and wiring harness. Great product. Easy install and looks great. Plug and Play.

    Highly recommended. (Posted on 7/22/14)

  10. Excellent Service! Review by Aaron

    Subimods provided some excellent professional customer service for my purchase. I brought a pair of silver Hellas and was impressed with the quality of the finish, looks amazing!!

    +1 returning customer! (Posted on 7/17/14)

  11. Excellent Products! Review by rroberto1

    Hella horns are terrific. Always have been.

    The Subimods wiring harness is a PERFECT piece though. Makes install ridiculously easy and their instructions are on point. The bracket for the horns just tops it all off. I must say, you COULD make your own bracket as it is quite a simple piece. If you're looking to save time and have a perfectly fitting piece, just buy the bracket.

    One of my favourite bolt on additions to date.

    Subimods customer service was absolutely perfect as well. (Posted on 7/16/14)

  12. Dope Review by David

    Look sick and sound loud as hell! Instal is tricky so first timers should ask for pro or experienced help! (Posted on 7/14/14)

  13. Super simple install! Review by Darrin

    Got the harness & bracket to go with the horns, which made for a slick & quick install. Had Hellas before, years ago, on a Mercedes-Benz 450SL. That pair was made in Germany, these current versions all seem to be made in India. They seem to sound the same, though. Subaru Forester specific install examples can be found at (Posted on 6/23/14)

  14. GREAT Review by James

    I bought this because... well lets be honest they look awesome peeking out of the grill. Install was very easy. I will say though, I ordered the basic red horns, when i received them, one was BRIGHT red and the other was a ugly BAND-AID color. So i just sanded it down and sprayed it to match the car, Spark Silver. Wasn't a big deal just a little bummed that the original red did not match. Whatever bc now the car looks menacing and scares the S**t out of oblivious Drivers (Posted on 6/9/14)

  19. Top notch quality Review by Gary

    My first order with Subimods. Highly recommend to do business with them. Their hella bracket and wire harness are second to none. High quality precision parts enabling the install very quick. I will be doing business again with them in the near future (Posted on 3/14/14)

  20. Great Product - Fantastic Support & Options Review by thomas

    I have to give thanks for the guys at Subimods-- their products are first class and their website gave great instructions. I also LOVE that they sold them in multiple colors. I went with black-- I prefer the subdued look of the black on black.
    Harness and wiring kit made the job easy and professional! (Posted on 3/1/14)

  21. Great Review by Elvin

    I received these pretty quick from Subimods and they have great customer service. My only gripe was the way the horns are packaged from factory. They're in a box facing each other with no foam or plastic and the paint rubs together, but it's not really noticeable once they're on the car. Not as loud as I thought they'd be, but they are way louder than the stock horn. Definitely worth it, especially if you live in a city. (Posted on 1/29/14)

  22. Subimods ftw Review by Noximus

    I bought my horn kid from Subimods as I couldn't find any other quality proven harness' or brackets any where else that was plug and play without any fuss or screwing around. Quality speaks a ton for this company.

    Because of this innovation, I was able to find this company, their prices and their deals are so amazing. The shipping is cheaper than other sites for the same delivery times w/ even faster processing time. Shipping prices are a huge deal for us Canadians. I've since made multiple other orders w/ Subimods and plan to continue in the future. (Posted on 1/20/14)

  23. Subimods Wins Review by Justin

    I've gone with other retails before, but ever since dealing with Subimods, I have gotten nothing but the best parts at the lowest price! Go with these guys, I see cheap imitations of their stuff and nothing compares! Always there for support if I needed it, they'll always have my business! (Posted on 11/29/13)
