That Darren is because you and I live in the real world where cars go fast, get stuck in traffic, overheat, hit other cars, and none of these home brewed gizmos would last 5 minutes!

Xmax time Darren, the alternator drive belt went on my late Mits, naturally it was mounted under the serpentine belt that drove the power steering, A/C and water pump. Great in a front wheel drive with about 2" of clearance between the pulleys and the suspension tower.
Wouldn't it be fun with three or more alternators.

One thing I do like about some modern cars - ONE serpentine belt.
Sure - it breaks and you lose water pump, aircon, alt, power steering and the idler pulley goes quiet....
But it is ONE belt and much easier & quicker to replace (than a "inner" belt).
It might take 2 days figuring out which path to wind it on - but then it is quick. Even quicker next time to match the serp grooves to the grooved pulleys.
I'm considering a serpentine, but that's for alternator only. No power steering etc, and I may convert my water pump to electric (by mounting a motor to the standard pump, AND adding a controller... did I write that I finally fitted a temp switch to my >30 year-old electric radiator cooling fan?).
As to parallel alternators, I like it when they don't tolerate paralleling, or when they (HO alts) are rewound standards that don't tolerate overloads.
The OP with the intended almost 15kW system has the right idea - an AC generator else a single DC generator (alternator).
Then again, why the 'L big amps do NOT split the supply from the output section beat's the 'L out of me!
And with >600V MOSFETs, it's easy running 4 or 8 Ohm speakers again....

In over 30 years around car audio, I've NEVER seen anyone with more than ONE alternator! Why would you want to do this? Who gave you the idea? I've seen some $50,000+ systems at some IASCA competitions and still never seen anyone running more than one alternator, even in systems pumping out several thousand watts.
Get a Capacitor or two and you'll be fine.

I vote this post a classic in entirety and the last line was put so beautifully it just iced the cake.

T&T - I recall the above yet cannot find it...
Surely if there were something wrong you'd be notified? (At least after the 2nd time...)
But I like those posts too...
Comparing max peaks to RMS...
Cost to power... (as if cost reflects quality or power!)
And of course the costly ammeter... (I'm sure it has some use...)
