building a sound board, need help

[tacomabanga1986]

well i got a few cdplayers and speakers and amps laying around that i want to make into a small sound board, now i will only be running 1 thing at a time and what knot so i wont be hard on my stuff

now to the questions

will this power supply be good enough to run a cdplayer and maby a 600w overrated 4ch with some speakers

and if so, i have one 100w power supply running my emergency light (a federal signal 184 power light 4bulb) and it does fine and i kno how to wire one up

but i was wondering, can i take all the yellows and solder them into some 8guage wire or something so i can make a small buss bar to hook stuff to? or do like what i did and just solder to some 12guage and use that?

i want enough current flow to still get clean sound, my 100w power supply wouldn't push the sony cdplayer enough so i think this 630w 50amp one will do it fine i think

and if not will this one?

this one is 56amp 700w for cheaper

what do yall think?

my plans is to wire the decks so i can just plug what ever speaker to what ever deck i want to to make it work

the 700w one has 2 12v rails so i guess i combine them to get 56amps if each one is 28amps?

im not looking for incar sound with this, just something cool to have in the room to play with every now n then and so i can try out stuff or show people radios befor they have me install them for them

Pretty sure PSUs don't like it if you combine the rails.

Yeah the 630w single rail one should work OK, although I'm pretty sure the 50A bit is lies. Still, should be plenty for just messing about.
