Can I connect a amp to the fuse box?

Connecting Your Amp to Power Resist the urge to hook up your new amp to the existing fuse box in your car or to an existing circuit or fuse. Your amp is almost certainly going to draw more amperage than the existing wiring is designed to carry. In the most basic terms, a fuse is designed to fail.

Can you power a subwoofer from the fuse box?

A powered sub should have a fuse somewhere in line, preferably nearer to the source. If attached to a main bus bar in a fuse box, thats fine, but it should have a consistent gauge cable throughout the length of the the run. for ease, it’s simply a best practice to run your own power lines for aftermarket accessories.

Which fuse should I connect my amp to?

The correct size of fuse to use depends on the amp you are wiring. If your amp has an internal fuse, then your inline car amp fuse should be a bit larger. For instance, if your amp has an internal 20 amp fuse, then you should go for a 25 or 30 amp inline fuse.

Does a sub need a fuse?

Some of you may not be aware that a subwoofer had fuses. However, they do, and you should know how to change it and the reasons it may have blown out. The purpose of a fuse is to protect equipment from over-current conditions.

Will amp turn on if fuse is blown?

If the fuse is present and blown, the amp can’t turn on because the circuit providing mains voltage is open. Simply replacing the fuse may or may not solve the problem.

How many amp fuse do I need?

B Calculate MINIMUM FUSE AMPERAGE by multiplying product amperage rating by 125\%. Minimum fuse amperage provides more protection for the wire but may result in nuisance blows. Example: 80A x 125\% = 100A. C Choose FUSE AMPERAGE near the middle of this range.

Can you have two fuses in series?

You could use as many fuses in series as you want. REDUNDANT! It makes no difference , if any fuse blows then the circuit will be open !

Why does my subwoofer amp keep blowing fuses?

In most cases, an amplifier will blow fuses due to internal damage caused by the way it was installed. An amplifier that blows the main power fuse immediately after you turn it on or when the fuse is inserted into the fuse holder is usually damaged in its power supply or output section, and will require serviced.

Why does my Sub keep blowing fuses?

The fuse blows because there’s a fault in the amp. It’s probably cheaper to replace the amp than fix it, assuming the driver is OK.

Can I use a 3 amp fuse in a 13 amp plug?

A 3A fuse is the safest to use and should be used for appliances at 700w or less. Appliances rated above 700w should use a 13A fuse. Be extra cautious when using a 13A fuse and try using a 3A fuse if and when it’s possible.

How many fuses do I need for a 100 amp sub panel?

If the existing range fuse holder is rated for 100 amps, then you can install two 100 amp cartridge fuses and use that position as the 100 amp sub-panel feeder over current protection device. A sub-panel feeder circuit needs to be protected by either a fuse or a breaker at the originating panelboard.

Can I connect an amp to a car battery?

The short answer is no. You’d only be connecting the amp to the battery power as the sub would be driven by the amp. The main fuse box of the car routes vehicle electrics and ancillaries through it. Each fuse is rated to carry the current that the particular circuit assigned to it will draw.

What should I do when my amp blows a fuse?

When an amp blows a fuse (or fuses, for amps with multiple fuses), you should replace the blown fuse with a fuse rated for less current. Let’s take an amp that has two 30 amp fuses. If the OEM recommended fuses blow, there is likely a serious problem. Fuses blow more easily if they’re warm/hot.

Can you plug a subwoofer into a power amp?

Some subwoofers have a high-level input that can accept the main power amp’s speaker outputs. (Check to make sure this feature is available before purchasing a subwoofer) In this configuration, the amp’s power is not being used by the subwoofer, just its signal.
