Has anyone tried this?

Its ghettoy but it works, with a battery isolator you will achieve isolation between your starting battery and auxiliary battery. When the vehicle is running the battery isolator will charge both batteries as long as there is a load. Under heavy loads, auxilary battery for your car audio, current will go directly to your alternator output. All your doing is using both batteries to run your car and your stereo.
If you play your music with the vehicle off you will drain both batteries, longer run time, but if you install a battery isolator only your aux. bat. will drain and your starting bat. will be fully charged.

What's you point? That has absolutely nothing to do with the topic at hand.

Electrically running a wire from the alt to the second battery is no different than going from the alt to the first battery to the second. Using good sized wire the difference in wire length is going to cost you less than 1 ten thousandth of an ohm which is less than a hundredth of a volt with a 100A continuous draw.

Thank you, that's all I really wanted to know. There's no difference. Thanks

The question was if there was any difference, pros/cons, in running one power wire from the alternator to the battery up front and a seperate power wire from the alternator to the battery in back, compared to a power wire from the alternator to the front battery and from the front battery ran parallel to the rear battery?

He actually had it clamped and that's what he was getting. People might not believe me but it's true. I've noticed in a few systems where people haven't upgraded there alt and still get most of the power out of their amps. I saw someone with 4 batteries and a stock alt. on a 40.1 and he was getting most of the power out of it too.

unless he is burping with a tone as he drives down the street, he will still never see "3800 watts".

music = dynamic.

clamping amplifiers = moot point. tell his *** to get a new alternator because he is killing his electrical system. as helotaxi said, there is no difference even if the alternator was in the trunk. distance = moot point with 0awg wire.
