When do you need to upgrade the electrical System?
 

I am debating on upgrading my current system, and would like to know when I would need to upgrade the Alternator/Wiring etc.
Thanks in advance.

When you pull more current than your current electrical system can handle/put out...

How Do I figure out how much that would be? I'm only pullin about 600 watts for my subs right now, and what I'm eyeballin would be about 4k watts.

I would at minimum upgrade your main ground wire.

seeing as your amp power wire is probably heavier then the wire that grounds your entire truck..

4kW is definitely beyond what your truck can provide stock. With 4kW you would need to upgrade the Big Three, alternator and/or extra batteries. If you want bare minimum though, I would install the system, upgrade the big three, and maybe add a battery and see if you still get significant voltage drop, if so, an alternator or two is in order. 4kW is a lot of power man.

Thought so.
Thanks For the advice guys.

what exactly do you plan on running that's "4000 watts"?

I was going to run 4 of these with a Lanzar 4K watt amp.

yeah i would't do that........ that is cheap flea market stuff honestly. probably puts out maybe 1/4 of rated power if you're lucky.

pyramid... HA. no offence, save your money and get one or 2 GOOD 12"s and it will be louder/clearer...

the main power wire to your truck isn't as important as you are running a seperate one to the amp. main thing is upgrading your ground and alternator wire.

there is a cheap (compared to the 'high output' aftermarket ones) that put out 200+ amps, which is roughly 2600 watts. I will see if I can track it down.


18"s are not good for listening, just spl. can't hit tight bass notes at all.
