In theory an op amp can be used as a comparator but in reality op amps are designed for other types of work so make sure you use an actual comparator. In most cases this wire is red.
What Does A Car Amplifier Do A Detailed Guide For You
How to make car amplifier. In this tutorial we are going to build a stereo amplifier that you can use to play music from for example your mobile phone or your computer. Depending on your configuration of choice you need the parts. If your amp is turning on just fine then youll want to make sure that its receiving an input from your head unit. Get a grip on the gainclone universe. Since you will be running it off 12v power supply more about that in further steps you might not get as stable power as you would in your car. The ground should go from the ground terminal of the amplifier to the ground of a car.
Make your first serious amplifier step 1. If you want to build your own amplifier then this is for you. Only a few components are. This is a pretty easy process if you have access to both the head unit and the amp simply unplug the rca cables from each unit and reconnect them with a good set. All you need to do is to connect power and ground wires to the amplifier. Car stereo metal mounting straps are fantastic for installation and will make building installing an amp rack much easier.
Drill a hole into your cars firewall to run your amplifiers power supply wire through. Create a pilot hole with a power drill and steel bit then use larger bits to expand the hole into the proper width to fit your wire after a rubber grommet is used. Make sure the hole does not have any sharp burr or it will short to the amp wires. You can buy them finished in black which i highly recommend or with the standard metal finish. Build your own amplifier. This step sounds complicated but it is incredibly simple.
9 straps are fine in most cases and you can buy a 5 pack or similar to save money. The power wire should go from the car battery to the positive terminal on your amplifier. Im not an audiophile and not an expert on amplifiers either. The amplifier is one of the simplest i have encountered and it gives out a decent sound. Car amplifiers are mostly rated at 144v and lower impedances 1 or 2 ohm for example while some home amplifiers can only go as low as 4 ohms. Because we need two outputs from the comparator one for the high side driver and one for the low side driver i decided to use the lm393ap.
