A: Primarily, a train horn signaling system will increase your chance of being heard in an emergency situation. Often, in the roar of high speed big rigs on the interstate, a stock horn may not be heard. Your new air horn system will be heeded in all situations, from a child about to run in the street to retrieve a ball to an approaching car about to drift into your lane. Oh yeah, did we mention that they are a lot of fun?

A: Kits are meant for easy installation. The concept is simple--basically, the compressor feeds the tank which feeds the horn. Components are powered by 12V standard DC vehicle power. Everything that you need including air hose, fittings and wiring is included in the kit. Still, figure at least a couple hours or more depending on the sophistication of your install. Follow the directions closely for a good installation. Don't forget to use thread tape on all air ports for an air tight install. Don't leave out any components. We can't be responsible if components fail due to an improper install or inappropriate operation. Your installation will go quicker with a knowledgeable friend helping out. Many users feel more comfortable hiring a garage to do the work. If you want to go this route, and you have no preference, we recommend contacting a business that specializes in alarm/remote starter/audio installations as they are very familiar with 12V DC wire-ups and running wires. There are several online step by step video installations you can so you will feel confident that you can install the kit yourself after watching.

A: We're here for you both before and after the sale via e-mail and phone support.

A: Most often items ship within 48 hours from order. In the continental US, shipping time is typically 5 business days. International order shipping time is commonly 1-2 weeks. We will contact you if there is an undue delay in the processing or shipping of your order.

A: Cheap kits are sold without regard to quality components. Expect two liter or smaller tanks (good for just a couple toots), cheap compressors that work slowly and noisily and inefficient plastic horns (even chrome ones). You get what you pay for. We have the best Maximus Horn Systems in all our price ranges, from entry level to ultra sophisticated.

A: Like watts for amplifiers, db ratings can be misleading. Under what circumstances were the decibels determined? How far away from the horn was the measurement taken? What device was used to measure? When was it last calibrated. Our horns are very loud. We design them right from the beginning. We have some systems that are so loud they will cause hearing damage so don't get too close when in use!

A: Yes. Our products carry the standard warranty from the manufacturer for these type components.

A: The larger the tank, the more blasts between re-fills. You'll have to balance tank size with the space you have in your vehicle.

A: Despite our manufacturers' best efforts, occasionally a part may fail prematurely. Sometimes a wiring problem may develop. Notify us if you have a problem. If we determine a part needs replacement, we will give you an RA number for repair or exchange.

A: By working with one specific manufacture it allows us the greatest pricing and warranty available. The MAXIMUS line allows more customization. If you would like to substitute a different part(s) in the kit, please contact us. We'll get back to you with a quote.

A: There is no "perfect" answer to that question. Your installation needs to be thought out as to where you want your horns, your compressor and your air tank mounted. Something that is especially important, though: No matter where you mount your horns, keep the air solenoid as close to the horns as possible. This will eliminate any delay in sounding the horns if you keep the solenoid close.
