Hey guys,

Do you know where I can find out about the detailed info about the specs of the OEM Stereo and amp for the 1st gen XB?

I am actually surprised there is no sticky thread with this info...

 

depends on the info you need

160w max total output for stock headunit. there is not stock amp, unless you mean the factory bazooka tube

 

there is also, I think, 3 diff option decks for the 04 besides the option Bazooka Base Tube (100 watts w/built in amp.
Which deck do you have? try searching the part# back/side of deck or T-(#)lower right of deck face to find more info.
the owners manuals for some of them can be downloaded from here.

Ah!

This is a great help. I will look through those docs.

I was wondering if there is a separate amplifier for the speakers in the stock model... or if the speakers are directly hooked to the stereo (assuming the stereo has the amplifier in it already).

 

If you have a stock deck and speakers and no one has modified the system then everything comes from the deck no separate amp. I think they are 165 watts total
