which battery to run amplifiers to?

[Supergumby5000]

I've never owned a truck with dual batteries under the hood before, so i'm just wondering which battery would be best to run my amplifiers off of?

I've had some serious serious stereo installs with large battery banks, and obviously i would link to the battery furthest away from charge (alternator) for proper drainage and charge reasons.

Can anyone tell me which battery the alternator/starter is ran to?

I'de go play around right now.... but its raining

I have my amp and compresor ran from the driver side. But the Ford Tech said to always "jump of" other people from the passenger battery.

The batteries are connected in paralell. If you drain one,you drain both.
You could consider a third battery underneath the truck with a battery isolator (as used in campers?) The isolator would permit the chargeing system to charge the battery...but be isolated for other purposes. A deep cycle marine battery would be best.

Batteries are parallel...so technically they are both "equi-distant" from charge. I would think that a line conditoner/capacitor set up in front of the amps will be all you need...also, you may want to run redundant chassis grounds, those two have always worked for me.

You should do the dirvers but it really doesnt matter. The passenger side is hooked directly to the started.

It does make difference because if you wear out the passenger side battery not drain it I mean make it weak the drivers battery wont be able to transfer as much juice through the cable that connects the two.

Not to mention there will be another battery in the way of getting the juice to the starter. Having an amp hooked to the starting battery will cause it to have to be recharged more.

Even though you think they get drained at the same time the accessory hooked directly to the battery will drain that one more especially if you are running say a 1000w amp. It will cause at least 700w to be drawn from the battery directly and the other battery will provide the other 300w.

Direct contact always is better so it will flow more juice from one than the other.

It actually does not matter and the minute amount of impedance in the copper wiring connecting one battery to the other will be immaterial to the current draw from EACH battery. Long story short-you can connect it to EITHER battery and be fine.

And if you're concerned about draw, upgrade the alternator and the related wires.

Either battery is fine but its much easier going through the firewall on the drivers side.

This is what ive been told.
