How to Pick the Right Wiring Kit for Your Car?

Though we have picked 5 best wiring kits out of all those available on the US market, we want you to know the parameters for a good-quality wiring kit. Here’s how to find the right one for your car:

Mind the gauge measurement

Before picking a wiring kit, make sure to check the measurement of the gauge in the kit. You can find lots of variety in the widths but we recommend you to start with an 8 gauge kit. Keep in mind that some companies claim that the wires have a specific gauge amount but actually, the length is smaller. Since the wires are wrapped in insulation, it appears to be bigger than it actually is. When you are purchasing online, we suggest you to buy from a reputed company as mentioned above. Also, check the gauge measurement as soon as you get your hands on it. If you are not satisfied, there’s always a return option available.

AGU or ANL fuse holder

A fuse holder is an important element in an amp wiring kit. Make sure to find out a kit that has an AGU or ANL fuse holder. These are quite easy to install and also has indicators.

Don’t settle for a poor-quality wiring kit just because it’s cheap

This one you already know – cheaper option is not always the better one! Especially, when it comes to an amp wiring kit, it’s better to purchase a kit with quality items. These are sturdily built and have enough longevity. If you pick a poor-quality kit, it will not last for long and you have to buy yet another one. Sounds silly, isn’t it? So, invest in a high-quality product that lasts long.

Which tools should be included in a high-quality amp wiring kit?

Pay attention to a wiring kit that includes all the essential tools to assist you in installation. We will mention some necessary items:

  • A positive wire which is about 18 Feet long
  • Speaker wire
  • Remote wire
  • Ground wire
  • A quality RCA cable that is about 16 Feet long
  • A fuse and fuse holder
  • Zip ties
  • Crimp ring terminals

If a kit contains more items, that’s even better. Also, if a kit doesn’t contain one or two of these items but the rest are of high-quality, you can buy the kit. In that case, you have to separately purchase the missing items.

Ideal size

The ideal size of an amp wiring kit depends on the RMS rating or wattage of the sound system. Here’s an outline on the size guideline:

  • 100 to 200 watts – 10 AWG
  • 200 to 400 watts – 8 AWG
  • 400 to 1000 watts – 4 AWG
  • 1000 watts and more – 0/1 AWG

Copper or copper-coated – which is an ideal option for an amp wiring kit?

Copper wires are pricier than the copper-coated ones. The copper ones have high conductivity and strength that underline their high quality.

On the other hand, copper-coated ones are made of aluminium. These have a low cost. However, you need not worry about the conductivity because the copper-coated wires have similar conductivity as the copper wires.

So, you can choose between the two depending on your budget. What are you still waiting for?
