does this mean i have to get better speaker terminal for my custom box then say....one at RadioShack?
ps....
Power 12.5 VDC Power 14.4 VDC
2 Ohm Load 1000 w x 1 2 Ohm Load 1500 w x 1
4 Ohm Load 500 w x 1 4 Ohm Load 850 w x1
how would i get the 14.4 power? RCA?
Well, it really depends on what subs you have....lets assume that you are running each amp at 2 ohm mono....
That means 1500W @ 14.4 V, now, let's assume that you have 60% efficiency - a bit conservative for a Class D amp, but conservative is good.
Now that's two amps = 3000W * 1.60 = 4800W of total draw
4800W / 14.4V = 333.3A of total draw!!!!!
Now you take out your little chart and check to see that 0/1 ga is good for 300A up to 15ft with a voltage drop of 0.5V.
Now I also checked the owners manual, and they recommend a 150A fuse per amp...so that's a total draw of up to 150A....
This is a SERIOUS amp. It also allows direct connection of 0/1.
What you will need is a 0/1 fuse holder or circuit breaker near the battery. The amps have no internal fuse, so you will have to fuse close to each amp as well, and run 0/1 ga to them. That is going to be expensive. If you want some of the cheaper 0/1 around, try sounddomain for Stinger Pro Series, or knuknoceptz.com.
So guys, telling this guy to run 4 ga, even one run to each amp is unsafe and won't work...do the simple math on this one!!!!
I would really stop and consider if you really want to run this much power in your car. This is going to put some EXTREME demands on any charging system (if you want to bump these alot) and especially on any honda charging system. Even oneof these amps is a current hog. You will have sever dimming problems.
Are you sure you need two of these?!?!?!!
Now IF you dropped to running these at 4 ohm mono, or one amp at 2 ohm, that's a total draw of approximately 150A....you can squeak by with 4ga, but Iwould still go with 0/1 ga to be safe.
