The amp im buying says it takes 4 guage... but its a 1600rms amp. I also have a amp on my door speakers that takes 8 guage but do i run a 1 guage and a distribution? Or do i go bigger and try to cram bigger than 4 in the sub amp?

You could run a 1/0 cable from battery to a D-block, and then place accordingly. You could run one 1/0 cable from battery, to a 1/0 to 4 gauge reducer, and then run a 8 gauge from battery to your mids/high amp.

the bigger the wire size you can fit the better

What amp is it?

get a fuse block like this stinger shd820 which has 1 0g in 2 4g out block like this , there should be a 8g reducer ring in it too

Or, snag you up a small battery for the rear and distribute off of that!

Its a soundstream rubicon 1600d on the ssd15. And my first amp i ever bought a pyramid classic on the front doors. Lol. But it works fine aslong as its not turned up too high... but so i should get a 1/0 power and distributer block. Alright thanks guys!

I like the battery idea!

Lol no room in an access cab tundra with only one less seat...

Lol and btw there is absolutly no possible way im going to spend 60 on a distro block... but ill get a cheap one on amazon
