I have one amp already hooked up for my sub it uses 4 gauge power wire from the battery and 4 gauge ground it is rated at 600 watts i believe.

I just bought a new amp for my door speakers. What will i need to just add the existing amp to the setup. I was thinking i could just get...

Distribution block , power wire ground wire, and speaker wire

Can I just put the distrubution block on the existing power line from the battery, split the power wire to the 2 differents amps. Then just ground the other amp and run the other wires to the head unit.


Will this be all i need?

You could- you consider amperage when choosing cables though, not the wattage ;p
You can find the amps current draw in the manual probably, or just check what kind of fuses it has and call that the current draw. My sub amp pushing 460wRMS (800 peak) has a draw of about 45 amps. I figure on about a 13' run.

yes. you actually NEED to use the same grounding point for both of your amps. This prevents the formation of ground loop noise caused by grounding at different locations of the chasis- which can have different resistivities. Id guess your drawing about 80 amps then. My amp i mentioned is 2x 40amp fuses and specs out @ 43 amps of draw. I edited my first post to have the chart is was supposed to have had.

meh, 16g is quite sufficient in most cases. Theres no reason to not use 12g if you've already gotten it.... except if your running it into door panels its going to be a miserable experience. If this is for subs, then go for it- but maybe you could hit up a local stereo shop and try to get some of their scrap wire; no reason to get a 20 foot spool of wire if you only need 3 foot of it.
