When you buy equipment from us, we can usually install it either immediately or after a short wait. No appointment is necessary. Of course occasionally we are jammed and may not be able to begin right away. Sometimes you may have to leave your vehicle. However the vast majority of the car install jobs we do are done for our customers right away. We find it amazing that customers put up with stores that can’t get them in for days, even though the customer is spending their money with the store. We won’t keep you waiting like that!

We install customer product every day. You don’t have to buy it from us.  Few shops in Kansas City will install car stereo products as quickly as we will. You say you need a car stereo install or to install car amplifier or install car alarm?  You say you need a car audio install for the used stuff you got from your friend?  You have  car stereo wiring problems? You need to remove car stereo equipment or a stereo removal? We help folks like you every day. Just be prepared to drop off your car if we’re busy. We’ll get your car stereo installation done that day. And often we can perform quick jobs like a radio installation or stereo install while you wait. Call us for an estimate or stop by and we’ll help you as soon as possible.

We do car stereo wiring repairs and installation troubleshooting on aftermarket car alarm & remote start systems and on car audio systems, both aftermarket and original equipment. You need a car radio installation repair or an upgrade install? We can do it. We can troubleshoot any product category we routinely install every day.

What is Troubleshooting? Troubleshooting is finding out what is wrong with the system and fixing it if we can. We do not repair the internal electronics of a product. We limit ourselves to installation repairs, car stereo wiring repairs and replacing defective product.  For example, we are often able to replace a defective car radio with a new one quicker and cheaper than repairing the old radio. If the customer wants a car radio repair instead, at least after our troubleshooting is done, you will know for sure the car radio is actually bad and that it is not something else in the system that makes the car radio sound bad, like a bad factory amp, bad speakers, or shorted wiring in the vehicle.  If you decide to repair your defective product, we can remove it for you and refer you to an electronics repair shop.  Most businesses that do electronics repair limit themselves to bench work only and do not test car audio systems in the vehicle or remove and reinstall  product in the car like we do.  Before removing the car stereo for repair, you better know for sure that’s what the problem is.  That is why troubleshooting car audio systems is important.   If it turns out you have bad product in your vehicle and you decide to purchase new product from us to replace the bad stuff at the time the troubleshooting is done, we can usually credit you back a majority of the troubleshooting fee toward  the installation of new product.

Thanks to our customers for their support over many years. We appreciate all the come back business we get from all of you. Without you we could not be here. Thank you, and as always, we are here to serve you.
