The reason your car speakers are getting quieter more at higher volumes is because they are not effcient enough to match the power from your radio. The best solution would be to install an external amplifier that can supply high output power to the front and rear car speakers.

IF you want to get technical, “speakers” usually sold in pairs. BUT there are center speakers which are sold of course individually, and subs are sold individually as well. Nowadays, the use of simple audio systems consisting of two or four speakers is in the past.

Turn on the stereo system and make sure the balance is set to the middle position. If the speaker still doesn’t work then the problem is somewhere between the amplifier and the speaker itself. It could be the speaker wire, any of the wiring connections or a bad speaker. Turn off the stereo system.

Typically when a car stereo produces no sound it’s usually caused by a shorted or grounded wire, defective speakers, faulty head unit/fuses, or setup is not yet complete with your radio unit.

A lower-gauge number indicates a thicker wire, while a higher-gauge number indicates a thinner wire. Speaker wires with lower-gauge numbers are better at carrying an amplified audio signal. However, for longer speaker wire runs (to another room, for example), it is better to use a thicker, lower-gauge wire.

If you have a modest system, investing in expensive cables may not be the best way to spend your money. Cables make a difference, but it’s a smaller difference than upgrading speakers, electronics, or turntable systems. The Cable Company also has a headphone lending library, for headphones that sell for more than $600.

If the level of amps is high enough, it can do some serious damage to your body tissues. It could even kill you!

So, can an amplifier drain your battery? The simple answer is yes, but a car battery can only be drained when it sends more power than receives back from an alternator. In this case, the amplifier will drain the car battery, even when the engine is turned off.

< 40 V is generally considered safe from an electrocution standpoint when the voltage is in contact with unbroken skin. However, voltages less than 40 V can still harm you in certain circumstances: If your skin is broken, all bets are off; even low voltages can harm you.

If a perfect storm of bad conditions presents itself, it is still possible for 24VDC to be lethal. However this perfect storm will not be present in a properly designed control panel, so it is safe for personnel to work in such a panel without any additional electrical PPE equipment.

It is perhaps worth noting that 12/24V DC is just as deadly as 120/240V AC. There’s naught deadly in voltage, it’s the wattage that electrocutes you. A static shock is 6kV, as I recall, but the amperage is low enough that it doesn’t hurt at all.

NO, , but it can easily cause a fire if short circuited. any voltage under 50 volts is considered safe to touch voltage.
