Few Things You Need To Know Before Installing Amplifiers!

Most of us geeks don't know much about amplifiers apart from the fact that 


"HEY IM GOING TO GET AN AMP IN MY CAR, YAYEE NOW MY SPEAKERS WILL GO BOOM BOOM!!"


When you go buy an Amplifier, the story doesn't end there if you're expecting to get Maximum output from your amplifier.
Here is a list of the "TO DO" things you must do to get maximum Output from any amplifier:




1. Using Proper Gauge (AWG) of amplifier cable:


AWG stands for American Wire Guage standard. What it tells us is the Standard diameter of the wire. Below is a list of few I quoted from rbe electronics for reference. You may check internet for AWG table:


AWG           DIAMETER
  20              0.03196118
  18              0.040303
  16              0.0508214
  14              0.064084
  12              0.08080810
  10              0.10189
   8              0.128496
   6              0.16202

From the above table it is clear to you, smaller the AWG number thicker is the diameter. But that is not the end of the story. Here is what calculation you will need to watch. Based on the power output and distance in feet, following are the recommended wire gauge sizes:

Always remember !!!! If you are using an under-rated wire Gauge then you are limiting the maximum input power that must be provided to the amplifier which will result in under rated output from the amplifier.


2. Using a Capacitor:

Adding a Capacitor is a good option. Capacitor stores energy for later discharge. This energy is usually discharged to an amplifier when it needs. In simple terms, when your amplifier is short of energy, the capacitor helps by effectively discharging during that period ensuring the amplifier performs at its maximum.

Nice article Dude...

Thanx man

alaa muzi , cant wait to get to correct this in my car :D

Thanx dude, glad to know you liked it..
