rockford fosgate p5002 wire size ?

[big scott]

hi guys,

i have an older rockford fosgate p5002 its a 2channel amp.

ratings

500rms x 1 at 4 ohms ( Bridged (Mono) )

250rms x 2 at 2 ohms

125rms x 2 at 4 ohms

i downloaded the manual but now were does it recomends a power/ground wire size.

so knowing the specs what size wire should i use ?

im going to install 1/0 " big 3 " and distribution blocks.

so i need to pick a block with that size output.

thanks guys.

I'd run 4 gauge to it, unless its gonna be ran as a sub amp, in that case I'd run 0 gauge for when you upgrade.

4 gauge will be fine no matter which way you use it 0 gauge would be overkill for a 500 watt amp

ok thanks guys.

but 1 more ?

ill be running that amp plus a 2 channel amp (75rmsx2 ) thats for my r.f. 6x9"

and i plan on getting a 2-channel amp (40rmsx2 ) for a set of pioneer 4x6 in my dash.

that all i plan to run right now.

so would the 4ga. be ok for this ? or should i get a 1/0

as i would run 1/0 to a block with 1 input x 3 outputs ( output 4ga to 8ga on all 3 )
