im upgrading amps from 200 to 1000 and i was wondering if the cables will restrict the current at all? right now i have a 225 watt cord set
200 to 1000 (if you have that much power) from 20hz to 20,000hz i would sugest a dedicated line .strictly for your home theatre gear,with a good power conditioner- with some good power cords,as well as speaker cables. also on the current issue the longer the runs of speaker cables the more current you will lose ,
The first consideration is how much power can your speakers handle without self destructing? My opinion is that few can productively handle more than a couple of hundred, and that would be for very brief peaks. The average listening level in a domestic situation is on the order of a few watts - 10 or less. If you really have speakers that can handle that amount of power, and you want to deliver it efficiently, then you need to keep the 2-way resistance of the wires from the amps to the speakers at less than 10% of the speaker impedance. So for 4 ohm speakers (worst case) you want the line resistance to be below 0.4 ohms. For a 50 ft (100 ft 2-way) cable run, that suggests 16 AWG minimum wire gauge for each speaker. Your existing RCA cables should be OK assuming they only carry low level signals. If your present power service and grounding are on a 15 or 20 Amp branch circuit (US) , and no other heavy appliance loads (refrigerator, washer, airconditioner) are on that branch, then it is OK for the new amps.
