Default what can a rangers electrical system handle

i was looking into getting new subs and for the power handling it would work best to just use a second amp. So the question is is the stock stuff good enough to handle the power? the only thing under the hood that isnt stock is the battery however its just a basic battery nothin fancy. So would this plan work or fail? thanks in advance!

You would need to buy a mono-block amp that would power your subs to their specifications and then hook them up.

Your alternator needs to be able to carry the load of your system. The battery is completely irrelevant. The alternator powers everything while the engine is running. But since you haven't actually said what you have and how it is setup, nobody is going to be able to give you any useful feedback.

Stupid response.

This. We need to know what amps your running. Also might help to know what ohm load you'll be running it at.

sorry should have put that info in. the amp i have puts out 900 watts at 2 ohms and i'd like to find another amp similar the that output. i would like to get 2 kicker cvx's at 4 ohms but wired down to 2 ohms.. if necessary i could just buy a new amp that could handle both but it would be cheaper to buy another amp for 2 amps in the truck. thanks for your help.

Ok. Really, the more people have to pry basic information out of you, the less they're going to bother trying to help you. No crap you have a Ranger.

- Year
- Model
- Engine
- Package
- Current audio setup
- Current power for the audio setup
- Other electrical add-ons
- Are you planning to use this with the engine off?
- How much money can you spend?

unless you have a completely crap alternator you should be okay running 2 amps. I have 2 amps in mine and have no problems just make sure your power wire is large enough to handle the load. and if you are going large enough a capacitor might not be a bad add-on.

Alright. Well its hard to say on the internet exactly how much current that amp will use since it depends on a lot of factors. So 30-40 amps is probably close. Figure the aftermarket head unit is probably drawing up to 10 amps. The capacitor is irrelevant as it can only provide very quick temporary juice (like less than a second). SO you're looking at up to 50 amps right now with nothing else added on.

I don't remember what alternator came with that engine. It would be either 60 or 90 amps, probably 90. Now remember, it is also power everything else in the truck. Engine, ignition, lights, HVAC, computer, etc. You are absolutely maxed out here. You audio system is using 55% of your alternator capacity. If you have the AC, wipers, and headlights on at night, you are probably at or over capacity already.

If you want to add another amp to this thing, you're going to need a much higher capacity alternator. You can probably find a 130amp off an explorer at a yard. Or have your alternator beefed up at an alternator shop.

Do an Expo 130 amp alternator and do the Big 3 with 1/0 wire. That alone will make a huge difference.

The primary power wire from the alternator to the power distribution box should be upgraded. Remember, it is sized to handle 90 amps at the most. The ground wires that go from the battery to the body and engine block should also be upgraded. The positive wires from the power distribution box to the battery should also be upgraded.

I don't have my handy wire gauge chart with me to say what gauge all that should be. I can check later on. Remember, the wires from the battery to the stereo components need an inline fuse within 12" of the battery.
