Where can you install an amplifier in your vehicle?Īn amp can be stored in a variety of places. It is always better to have a little extra power in your amp than not enough. Your amp should be able to put out 75 to 150 percent of that RMS number. First, find the RMS value of your speakers. To power a system, you need to find a product that can handle the load. How much power is needed for an amplifier?Īmpilfer power is measured in wattage. If you want to achieve the full potential of the amp, you should have each component on a separate channel. You can share channels with other components as well. The rest of the channels are designed for your speakers. An amplifier will have a mono channel for the subwoofer. Next, I took the fuse I tested in it and plugged it back into a working amp of the same model, which ran fine (so I know the amp isn't just killing fuses). I replaced the power cord and fuse with known working ones, with no result. The Hifonics amplifiers offer one to six channels. 213 Posted: Options Why won't my Amp power up I have an A500 Behringer power amp that will not power up. For example, if you have two speakers and a subwoofer, you will need at least three channels. You will need a separate channel for each stereo component. How many channels are needed on a car amplifier? An amplifier can help push power to the equipment without any loss to the music. Some components do not have enough power on their own to drive the sound. Without it, your sound will be quieter and contain a lot of distortion. It is the power the drives the speakers and the subwoofer. Why do you need an amplifier in your car?Īn amplifier is an important part of your car's audio system. The amp is the force behind all of the components. The subwoofer will help to drive the bass and add depth to the music. You need them to let you hear music with clarity and without distortion. The speakers deliver your first experience with the sound of the system. There are three important components of a car audio system. What components make up a car audio system? Hifonics has a long line of products to help you get the sound you're looking for. Subwoofers, speakers, and tweeters are among the components you can install for improved audio. If you would like more than a stock audio system for your car, you can always upgrade. Avoid bending the power transistors leads once you remove the screws holding the circuit board from the heat sink.Upgrade Your Car's Audio System with a Hifonics Amplifier I suggest taking good (clear) pictures of everything before you pull it apart. This amp has huge potential, by design, but crippled by implementation. Replacing the twisted output wires with OFC similar temp rated wire or even untwisting the OEM wire can't hurt either. I would recommend replacing all the screws you remove because they will disintegrate on contact. Note replacing the caps requires removing the amp circuit boards.which means disconnecting the heat sinks.lots of little bits, and heat sink paste. The best choice would be splitting the required value over several small caps connected in parallel. ![]() Replacing these caps should put you back in service.Ĭap coupled amps sound bouncy.Pulses are accelerated and then fall off.So the choice of replacement cap will effect the tonal quality of the amp. The lower the impedance of your load (speakers) the faster this will happen. Therefore if you drive high currents of low frequencies the large caps will is a very graceful failure. The two large caps form a center tap for the power supply which is connected to the speaker terminal. And it worked!! There was probably a loose connection or an oxidized lead. ![]() Plugged everything back in where is was supposed to be, and turned the power back on. Everything checked out ok, so I turned power off. Use a multimeter to check the voltages coming out of those two power cables, they should be somewhere around 70Vrms.ġ0. Use extreme caution, there is live 120V leads in areas that you can touch with your hand! I recommend using only 1 hand while anywhere near a large voltage, incase of any shock, the current wont go through your heart.ĩ. Now the scary part: unplug the power cables (yellow and orange) going from the huge inductor/transformer to each of the amplifier boards, and then plug power into the amp and turn it on. Checked to see if any of the electrolytic capacitors had "popped tops" (if they had blown)Ĩ. Used a multimeter to check every easily accessible diodeħ. Removed and checked continuity of the power connector through that fuseĦ. Removed and checked the two fuses on each of the amplifier circuit boardsĥ. Removed and checked the front ON switch for power continuity (with power turned unplugged, just use a multimeter on continuity check.Ĥ. Plug it in to make sure it doesnt just turn on, it didn't so unplug itģ. Pray that God would be glorified through anything I doĢ. You could bring it by my church either this coming new years or this saturday night. Is there a way we could meet up and I could take a look at the amp for you. ![]()
