Question 1

Does it comes with the fuse?

Accepted Answer

Let’s not forget that the gain and that the pre amp input voltage.  The sensitivity doesn’t control the output of the amplifier. It’s just a sensitivity to the signal. That’s why at minimum. The voltage is higher and that maximum the voltage is lower. It’s a gain.  Higher preamp output, lower sensitivity adjustment. In reality were amplifying this signal, and the signal is controlling the MOSFETs N-channel most likely.  Speaker sensitivity is one watt at a distance of one meter.  Lower quality speakers usually have a sensitivity because they have small motors and require less work to move based on the calculation.  A watt is 1 joule per second.  It’s work.  For examples 746 watts is equal to one HP.  So an amp that puts out several thousand what’s is an amp that can do a lot of work.  That’s why it’s louder and can move a large motor very fluid and effectively.  Basic rule of thumb but not 100% accurate voltage multiplied fuse rating.  Voltage is electrical force. Amperage is the amount of electrons flowing through the circuit to maintain the voltage. As long as resistance remains constant. Find that electricity actually moves in about 1 m every 3 to 4 hours. It’s the electrons that jump from atom to atom is how current flows And current won’t flow without a potential of difference

Question 2

Will this work for my two 12 at 4200w with a 1600w 2 chanel amp

Guys, a fuse is for over current protection.  If the M shorts and draws more current than the fuse is rated for then the fuse blows heads. It’s a fuse, not a resistor. We’re talking about amplifiers, and what they do is amplify the 12 VDC input into a higher VAC signal.  this is because we use transformers that operate on the principle of mutual induction.  A magnetic field is turned on and off rapidly to induce a higher voltage based on the principle of mutual duction, which in turn, creates an AC voltage because it is fly back. The way you control the amplifier output is through the resistance or impedance you place on the speaker channel.  Less resistance more current more voltage, higher resistance, less current less voltage. Ohms law. I hope this helps.  Lubbock. That guy was rude and is wrong too.  I’m academic went to college for electrical engineering.  If you have any questions please feel free to ask.  Remember, if use is only for protection of the amp.  A fuse by design has an amperage rating when there is a short amperage rises infinitely so if use is rated for 200 A if 201 A go through that fuse because there is a short to ground, the fuse will blow to protect the component. It’s not a resistor. It doesn’t control the flow of current. It’s a channel for current to flow. Anyway, it likes. As long as it doesn’t exceed the fuse rating

Question 3

Can I hook this up to a 3000 watt power drive inverter in my semi truck?

Accepted Answer

Depends on how far your inverter is from your power source.. this is a zero gauge rated cable... im pushing a full 200 amp light system with mine with no issues..  hope it helps

Question 4

I have a 15 in sub 600w rms 1200w max and a 1800w amp 5chanel. What wire gauge do i use?

Accepted Answer

In my own experience 0gaugebis always the way to go with running a high watt amp it
