first of all i have an original HU-650 in my 2006 S60 and according to mathews volvo site i have 4 ohms speakers in the doors (unconfirmed by me) and 8 ohms in the shelf (confirmed by me)

im going after market with a pioneer AVIC-F77DAB which is 4 ohms im getting people saying i shouldn't use 8 ohms speakers with it its going to damage it but according to an audio specialist it shouldnt cause a problem it would only cause a problem if the ohms were lower not higher.

anyway i might want to change the shelf speakers not sure if i need adapters or not? also anyone done this and found any after market speakers? not after high power just something average.

also im told i may have a hidden amp i definitely dont have an external one under the seat thats for sure but im told its possible there may be one elsewhere and i was told i could check it by using a multi meter on the speaker wires behind the stereo but not how to test it!
