What is the best way to wire 2 svc 2 ohm subs with a Rockford Fosgate T500 1db?
How much power can the subs take in terms of RMS wattage? You can either wire them to a 4 ohm load where they will each see 125 watts, or to a 1 ohm load where they each get 250 watts. Rockford Fosgate supplies a very useful feature for showing how to wire the subs for the impedance that you want: http://www.rockfordfosgate.com/rftech/woofer_wizard.asp
Can a 14 AWG solid copper wire that's 15 feet long carry a load of 40 amps?
No, a #14 conductor is only rated for 15 amps. If the wire insulation is rated for 90 degrees C and is connected to a 90 degree rated circuit breaker the ampacity can be raised to 25 amps.
Will awg 10 wire carry 30 amps for 30feet?
Yes, a #10 wire will carry 30 amps for 30 feet. If the load is rated as continuous then the wire will have to be derated to 80% capacity which will leave you with 24 workable amps. If the load demands currents higher that 24 amps then you will have to go to the next wire size up which is a #8 which is rated at 45 amps.
If you have two 150 RMS watt subs on the same ch of an amp What is the RMS watts needed from the amp?
Depends on the impedance of each speaker. If they are car subs and not converted home speakers, they are probably 4 Ohms each. Depending on how you wire them you get either 8 Ohms or 2 Ohms. 8 Ohms is not a problem load-wise for the amp, but if it is rated at 100 watts into 4 Ohms, then you will only get 50 watts into 8. Many car subs nowadays will handle a 2-Ohm load, but some will not. Your two speakers will handle 2x150 watts or 300 watts. An amp that is rated to drive 300 watts into 4 ohms will either deliver more like 500 watts into 2 Ohms, or it will melt through the floor of your car. So you need to look up the specs for your amp in the instruction manual. If it will only run into a 4-Ohm load, you can only use one 4-Ohm sub per channel. If it will handle a 2-Ohm load, you will have to turn it up slowly or you will blow your speakers out. Mr Ohm and his law will not be denied.
In selectecting the wire size for a line cord you should remember that?
The wire size is large enough to carry the load current and that the cord is properly voltage rated.
Why after buying a new CD player when the radio is on would the subs work but when you put in CD the subs do not come on?
make sure amp remote wire is connected to p.cont wire and not power ant wire on the radio
What wire size do you need for a 3phase 80amp 60hz 220v load amp 68?
A #4 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 85 amps. This size wire will also be the same for a load amperage of 68 amps as the next wire size smaller #6 is only rated at 65 amps.
How much does it cost to get subs installed?
generally 65 dollars, unless you have to buy the wire from the shop who's installing your subs
Which wire used single phase 240v 6.5kw load?
I = W/E. Amps = Watts/Volts = 6500/240 = 27 amps. A #10 copper conductor with an insulation factor of 90 degrees C is rated at 30 amps. If the load is continuous the conductor can only be loaded to 80% of its capacity. 30 x 80% = 24 amps which is too low for your load. Move to the next size wire which is a #8 which is rated at 40 amps x 80% = 32 amps. As long as no long distance runs are involved this wire size will work well.
How do you tell which is the line wire and the load wire?
The line wire will be hot and carrying power when the breaker is on. The load wire will not be hot and will have no voltage on it until it is connected with the line wire.
What is remote wire for car amp?
remote wire is to control amp, bass coming from subs, and the frequency
What happens when you connect the line wire from the switch to the load wire from the wall?
This is what the purpose of a switch is. It connects the "hot" wire to the load. When this is done the load becomes energized.
