The Grey Goose Posted March 11, 2017 Share Posted March 11, 2017 This walk-through won't be as in-depth as my others (sorry). I was too excited to get it all installed to take a whole bunch of pics. If anyone has any questions as far as wiring goes, just let me know! So this is my homemade quadzilla. I found their price for the bracket and wiring harness absolutely insane, so I decided to make my own. The bracket cost me $8 to make, and the wiring harness was essentially free. I used one of the wiring harness that came with my HID kit and re-purposed it for this with minimal effort. I decided to go with two pairs of sharptones solely because they were a little cheaper. At the time of purchasing, two pairs of sharptones were $60, and two pairs of supertones were $80. Things you'll need for the bracket: 16" aluminum bar Drill with 3/8" drill bit Angle grinder/hacksaw/cutting device M8-1.25x20mm bolt ratchet with 10mm socket 1/2" open ended wrench Thing's you'll need to wire the horns: Relay 16 guage wire In-line fuse holder w/ 15 amp fuse Misc. electrical connectors Wire crimpers/strippers/cutter Optional: Heat shrink Soldering Iron All four of these horns combined only pull 14 amps, and a standard automotive relay is typically 30 amps. If you were to do four Supertones, they pull 22 amps, so one relay will still be fine. If you go that route, I'd recommend beefing up the wire to 14 or 12 guage wire. First off, drop your bumper. It may be possible to do it without taking it off, but it is much easier with it off. http://i707.photobucket.com/albums/ww76/ticonderoga16/Quadzilla%20Install/IMG_0693_zpspelzsdrh.jpg The horns come with these ~3" metal bars on the back, but you'll need to remove them. This is where the 1/2" wrench comes in handy. Beware, these suckers are TIGHT. It took some serious muscle to get them undone. An impact wrench would've made my life a lot easier. Then, make your bracket. The bar is sold in 36" increments, so you'll need to cut it. I made mine as narrow as possible and was able to make it 16" long, but you can make it up to 24" long and still have it fit in the grill. http://i707.photobucket.com/albums/ww76/ticonderoga16/Quadzilla%20Install/IMG_0695_zpsqqmhyvqu.jpg http://i707.photobucket.com/albums/ww76/ticonderoga16/Quadzilla%20Install/IMG_0696_zpsolzyeywt.jpg Double check and make sure it all fits nicely and fits in the grill. http://i707.photobucket.com/albums/ww76/ticonderoga16/Quadzilla%20Install/Untitled_zpsmlw5f0ua.jpg Figuring out which connector and which was positive wasn't easy. They're not labeled and there's nothing on the box, I tested a horn with my drill battery, and it honked regardless of which connector was which, so I'm unsure if it really matters. In the picture below, the connector on the right side of the horn I used for ground. Wire all your horns together. All I did was use the female spade connector one size too big, twisted them together and crimped it on, followed with some heat shrink. http://i707.photobucket.com/albums/ww76/ticonderoga16/Quadzilla%20Install/IMG_0705_zpshwuuc2ld.jpg I left the final ends open ended until I got the relay in place, then connected them to the relay. Next up is wiring your relay. Using a relay may seem a little complicated at first, but once it clicks, it's very simple. http://i707.photobucket.com/albums/ww76/ticonderoga16/Quadzilla%20Install/Wiring%20diagram_zps5z1uxezj.png A regular male spade connector fits in the stock horn plug. http://i707.photobucket.com/albums/ww76/ticonderoga16/Quadzilla%20Install/IMG_0700_zpsyhryik57.jpg Right next to that is where I grounded the relay. http://i707.photobucket.com/albums/ww76/ticonderoga16/Quadzilla%20Install/IMG_0699_zpsgpuhmtbv.jpg Here's where I grounded the horns. http://i707.photobucket.com/albums/ww76/ticonderoga16/Quadzilla%20Install/IMG_0701_zpstu0xgtlu.jpg Link to comment Share on other sites More sharing options...

The Grey Goose Posted March 14, 2017 Author Share Posted March 14, 2017 Here's all I've got for now. It's snowing here, so my car is staying garaged while we drive the wife's Impreza around. Once it's nicer out in a few days, I'll get a couple good pics! http://i707.photobucket.com/albums/ww76/ticonderoga16/Quadzilla%20Install/IMG_0697_zpswovwwf1i.jpg Link to comment Share on other sites More sharing options...

WRX USA Posted March 20, 2017 Share Posted March 20, 2017 Looks like the passenger side is ever so slightly lower than the driver's side. Link to comment Share on other sites More sharing options...
The Grey Goose Posted March 20, 2017 Author Share Posted March 20, 2017 That's quite possible. Doesn't bother me though since you can barely see the horns from the front anyways. Link to comment Share on other sites More sharing options...
