Gathering info on upgrading the Bose system - some questions

[Doug427]

I finally got the Bose box out of the car and opened it up, only to be very pleasantly surprised to see that someone had replaced the Bose drivers with Focal K2 Power 13KS woofers. The wiring seems very strange, they wired to the subs to an amp, and drove the tweeters in the Bose box with the radio amp. Very strange, but it's all being redone anyway. Dash his original Bose drivers, that'll be front channel. Door speakers are still unknown, I have to remove a door panel and see what they are. Whatever is in there or their replacement will be rear channel, and the two Focals in the Bose box with be single channel sub channel on it's own 250 watt mono JL Audio amp. It should sound decent.
