Re: New Apline CDE-103BT install and some other stuff...
Good choice on the alpine head unit, I run a x-305s myself.
The alpine power pack is a great way to add power to the regular speakers as it only needs to plug into the wiring harness and then into the radio, think of it as an extension cord that adds 300 watts rms of power.
