DIY: Make your own Quadzilla


Recommended Posts

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.

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.

Double check and make sure it all fits nicely and fits in the grill.

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.

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.

A regular male spade connector fits in the stock horn plug.

Right next to that is where I grounded the relay.

Here's where I grounded the horns.

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!
