My First post and I need help deciding on an amp install kit.

I am assembling a modest system for my truck, I am currently only running 1 amp for the sub but I may add a 4 channel amp for the speakers depending on how it sounds.

Can I install 4 gauge wire now and use a smaller fuse, or install an additional smaller fuse close to the amp? (it's only a 200w amp so it wants a 40amp fuse).

Does this future proof me if I want to add another amp or is it a bad idea? Could I run two modest amps (200w + 200w probabaly) off of 8 gauge power?

Thanks.

Always run bigger than you need because sooner later you will want to add more stuff. This stuff can get addictive and enough is never enough.

 

Wizard is right, i'd prob just go with 4 ga, you will, I repeat, yOU WILL get more equipment down the road, and you'll be glad you went big on the wire. saving you alot of work in the end.

 

4 ga good for 150amps, I doubt your alternator will put out that much... should be just what you need. But what do I know I used 1/0 gauge(I could arc weld with the stuff)! Now that's some impressive looking wire! No voltage loss there.

 

the fuse in the power wire is more or less to protect the wire (from melting/burning). the amp will have its own set of fuses to protect itself. so putting a small fuse in the positive wire to amp will only likit the power the wire will carry. Normally you would put a fuse inline that is rated at what the wire can handle.

hope that helps
