How to install a wired fuse between battery and amp

Fuse rating is based on the guage of wire it's to protect.
Install the fuse holder close ...within a battery positive connection.
You may require a different battery cable clamp to accept your new amp wire (and the existing wiring).
Occasionally, it's possible to use an unused location in a vehicles power distribution panel (the fuse box close to the battery - under the hood). Sometimes appropriate for small to mid-draw amps, in certain vehicles, where some high draw options were not factory installed.

How to wire ammeter guage in 1988 GMC C1500

Most people use a volt meter instead of amp. The problem with trying to hook up an amp meter is you need to run all of the electrical components thru the gauge and they are not heavy duty enough to carry the demand. A volt meter can be connected to any battery source such as the cig lighter.

Power cable size and fuse size for boss riot r1400d caraudio amp

you need to determine how long the wire run will be from the battery to the amp then check
this link will allow you to know what guage and how far at what amperage ,A rule I use is look at the fuse or fuses in the amp and match the amperage fuse at the battery ,no more than .The fuses in the amps are usually above the current that the amp will pull from the car battery .or alternator when running . That amp has a large power supply and runs low impedance (it will pull power from your car )Think about a capacitor ,unless you are installing in a truck with dual batteries .

My audiopipe amp went into protect mode randomly. even though i have to prevent fuses on my power wire

Ok, for starters you need to clarify if you are saying you have "two" fuses on your power wire. That's what I get from your statement. My question would be why? As long as you place the initial fuse within 12 inches of the battery, you're cool. The purpose is to stop the flow of power in the event of a spike so that your power wire doesn't fry and cause a fire under your vehicle carpet. Second, your amplifier should have fuses that trip when this occurs too. If this has been occuring since you installed the amp, you need to recheck all your wiring (I recommend removing the extra inline fuse). Two things trigger an amps safety mode. 1- an amperage fluctuation or overload. It will sense when there is to high or too low of an amperage flow. Too much fluctuation can damage internal components. 2- Your amp is malfunctioning. If you have an internal short, this could occur. (really it's tied to the first one because it is sensing that the short is allowing a full flow of power at the short, thus causing a fluctuation). Start with the ground wire. Most amperage problems happen because of a poor ground. Think of power like water. If you have a good flow coming in, but poor flow going out, it gets kinda....backed up. This causes a fluctuation of the amperage since the electrons cannot flow properly. Setting off the protection. The other thing to thing about is the correct guage of wire. If you have too small guage wire, the amperage will dip low during heavy usage, causing the other extreme of the fluctuation.

Check what you have. If you are running a load of 50-65 amp (look at the fuses on your amps and add them up), then 4 guage is good from 13-22 feet. If you are running any higher than that, you will need 2 or 0 guage wire. You will also need to make sure to have a fuse slightly higher that the amperage draw you are expecting. As always, make sure your power and ground wire match. I have seen alot of kits made with smaller guage ground wire. They work of the premise that the shorter distance produces less resistance, thus requiring smaller guage wire. I say why risk it. Always use a multimeter when checking for proper ground placement. Also, if you are going to use aluminum or tinned wire (trust me, it's out there), you will need to increase the guage of the wire.

Happy hunting

My 98 villager sat for 3 months and when we drove it again the power locks, power windows, dash lights, and blower motor stopped working. I have changed the fuses and nothing has helped. What could it...

Depending on where in the world you are. Especially if it sat during the cold months, this is often common with power features.

Could be that your battery is just weak.
This is in reference to the second portion of your post.

However, part of your post mentions problem with Car Speakers and Subwoofers

You did not mention any fuse or what gauge power wire your running for the stereo Ampilfier
(which your powering those subs with)

Without those, you can quickly drain a battery, and very easily cause some serious damage to your cars electrical system.

So, without assuming you have a secondary battery for the stereo, I would reccomend that you obtain a power wire (I only use 0 Guage, but reccomend a min of 4, do not cut your car short here trying to save money by installing 8 guage). Also install an inline fuse (I use a lot, 150 AMP, 90 would be Minimum) within 18 inches of the battery before sending the wire through the car to a distribution block in line and ahead of the Amplifier.

Also, depending on the size of your Amp and Sub's you may need to upgrade your Alternator to a 100 AMPs.

Hope this helps

Good Luck and Happy Motoring

I have one of the power acoustik a2100d and it ceeps going into protection mode any suggestions will be greatfull thanks liam

This could be due to one of a couple things:
- Speaker wires shorting out against each other (or the speaker may be shorted out itself)
- Not enough current coming through the power wire (check power connection, ensure you are using big enough wire, i.e. 4awg)
- Not grounded well enough (check ground connection, make sure chassis ground is against bare metal and solid)

Im trying to hook up my subs to this headunit but i cant get the power from it to the amp. The amp is good and the subs are good

have you got a wiring kit for the amp? the amp needs atleast an 8 guage tho id suggest a 4 guage running from the batter to the amp with a 50 to 80 amp fuse atleast, then it needs to be ground to the chassis. a remote wire then needs to be run from the back of the headunit so that the amp only turns on when the ignition is on, then hook the wires from the amp to the sub.

03 impala there is a factory installed amp all speakers. i am trying to find out if i can power another amp 760w pioneer form the amp that is already there? i have already put outputs for my RCA wires. can...

You might not want to do that. The 760W Pioneer amp might require larger wire due to the power consumption of the amp. Most amplifiers require a direct wire from the battery to the amp. The power wire for the factory amp might not require very large wire and if you tie into the power for that amp the fuse could blow and wiring in your car could melt or catch fire, The best installation is to run the recommended guage wire from the battery directly to the amp with a properly rated in-line fuse.

Installing The Subwoofers to the amp... etc.

You should go with a 4 guage power wire kit. If your amp is going in and out
at high volume than that is your problem. 8 guage will work but, if you want
the proper current which is your power from your battery, going to your amp
than I would recomend the 4 guage amp install kit or just the main power
wire coming from your battery. If you would like contact me and I will send you
to a very good sight with all the info you will ever need for car amplifire installation.
