Mulitiple Amplifier Power wire rating

Post by jar_jar89 »

which gauge wire? im gonna be running one 500watt amp and one 600watt amp. i currently have 1000watt 10gauge power supply, do i need to upgrade it to sumin like 1500 8guage wire or will i be good to keep the current one? the 600watt amp will only be pushed to about 75-80% output with two subs bridged and the 500watt sub will be for a single set of 6x9's. the RMS ratings are all sound and will result in a safely matched up system. i just wanna know if i should upgrade the power and ground cables?

and i know this should really be in ice etc forum but it always quiet ova there 8)

run both from battery from a power distribution block. hence wondering if the wire from battery to distribution block needs to be 4 or 8 gauge then i know i can use 10guage from dist block to each amp.

4 guage. there is no point risking a fire and detroying all the amps, so go four to be safe. Also you need to make sure you work out the right fuse rating, which is Extremely important!
