As many of you guys seen my post i have finally came to a conclusion on what to get as far as equipment.

So Im going to install 4 JL 770, a JL 400/4 and a Clarion CDM-6 in my boat.. It currently has 2 battery, Walmart ones. (EverStart Maxx Group Size 29 Marine Battery) i think it has a 75A alternator...

Im planning on playing music for about 6hours, and i dont want to go back to my boat and have one battery dead, wondering if the battery switch is enough?

Also i know i need a fuse for the amp, On the JL400/4 manual says that it needs a 50A fuse, so as far as the fuse block what should i get?

Edit : I see people recommending wiring the ground of the amp somewhere close to the amp, like 4ft max from it to like a chassis or something... Since the amp will go in a cabinet the only ground cable i have there is a 16 gauge cable... So the other option i have is what i said before just run the cable all the way back to the battery (15 ft)

on a large stereo install you need to install wire from the battery via a fuse and skip using any wire thats already on the boat this includes positives and grounds sized for the ampage required over the distance used. buy a single fuse holder for the 50 amp from a auto or audio store as you require a fast blowing fuse that limits current which is not a real requirement for a boat system (trolling motor,etc)

Thank you... But since the HU wont have any speakers running of it... It will probably use what 2A? Also is the remote (from HU to the amp) enough as a switch? or i should add a dedicated switch to the amp besides the fuse?

its not always about ampage when it comes to wiring sometimes its about electrical things playing with each other which can be a little static with the motor running or a poping sound when you turn on a pump which is why its best to run from the battery or a buss. if theres no bad connections on your boat you will proberly never see any of these problems but then again it is a boat
