whining, 300 amp alternator, 93 civic

I just finished installing my 300 amp iraggi alternator into my 93 honda civic si, I did the big 3 and installed my system.  Right now that consists of 2 MTX 9500 subwoofers with 2 TA81001 amps as well as a clarion 4 channel amp currently only running the fronts...as im waiting for the rears to get to my house...been waiting for 4 weeks for them to be in stock.

Pretty much when I turn on the head unit my car hesitates a bit...I assume this is from the remote lead turning on all three amps at once...however if I pause the music or even listen to it at a low volume I hear a high pitch whine.  Is this that whining that people say is related to grounds?  Can this damage my amps or head unit?  The car?

Also.  Under the hood I have one optima red top.  My friend at school wanted to hear the subs at full power for a couple seconds.  So I started the car and then turned them up but almost instantly I heard a VERY loud sound from under the hood that sounded very similar to when the alternator belt is slipping on the alternator any ideas as to why this might have happened?  From my understanding I should be able to play the system even in idle if not for too long since the alternator isn't outputting the 300 amps at idle.  It shouldn't be causing the alternator belt to make a sound like that though correct?

Lastly...I have an Optima red top battery with the big three upgrade and a 300 amp alternator yet my head lights still dim ALOT when I turn my subs up loud.  Any ideas?

Thanks so much.

When the alternator kicks in, it wants at least 7 hp to drive it, the motor probalby produces 20 hp at idle, so its bound to stumble.....

If the alt. isn't lined up straight, or the brackets are not strong enough, the belt will squeal, and the belt must be tight.

It took us a few weeks to get it right, and a number of belts.  You should run more than one battery if running hard.  The alt will produce 300 amp at a specific rpm, at idle it might produce just slightly more than the stock one, so you need either more rpm or more storage.

If you pushed the system hard, without proper power you could have blown the grounds off the deck, resulting in the wine.

What do you mean blown the grounds off the deck?

?

AND, you never stated what type of head unit.

Not a Pioneer by chance is it?
