Fuses

So i bought a new 160 alt. and im going to give it 0/1 gauge wire from the alt to battery. Now i heard that you need a fuse that matches the alt max rating near the battery. ok, being new to installation does that mean lets say get an anl fuse holder and two 80 anl fuses for each side or how does this work. totally new to this

you need at least 2AWG cable from engine to chassis, battery negative to chassis, and alternator to battery positive.
on the alternator to battery cable, you'll want a 160-200A in-line fuse or circuit breaker.
This is strictly to protect from a fire in case the wire melts or grounds out and starts throwing sparks and arcing around the metal under the hood.
The fuse doesn't have to be exactly 160A because in the case of a dead short, it's going to blow instantly anyway.
you'll also need a fuse for the same purpose between battery and amplifiers, near the battery and rated for around the peak current capacity of the wire itself. 0AWG is rated for 325A so anything around there is good.
at the distribution block you can use smaller fuses for each amplifier to protect the amps themselves... using fuses rated for the peak current draw of each amp respectively.

an 150 fuse to much for a 80amp fuse rated amp?

the fuses under the hood aren't to protect the amplifier.
they are to protect the wire itself, and the car.. like I alraedy said.

oh just for the amp?
yeah if the amp is rated for a pak of 80A, stick to the 80A fuse.. not a 150.
you want to keep the fuse ratings close on the amplifiers.. those are the ones that protect the amp itself
