Amplifier or not?

[Gordon]

My '05 E53 X5 is in dire need of a head unit upgrade. I have been told that I need to know whether the head unit powers the speakers directly or via an amplifier. I have no idea which and would be grateful for any info.
If it is powered by an amp where do I find ?

Depends upon the kit installed now.  If you have sat Nav then you have a boot mounted BM54 Amplifier down by the battery (under the boot floor).

Thank. Took it to a Audio fitter this morning and having a Pioneer system fitted next week.

Eh up Gordon,

I’m not far from you, really interested in this upgrade as I’ve got the single slot cd and basic business radio.

Any picks after it’s done would be appreciated, plus who you used and if you rate them.

Cheers in advance

It's a place called Automotive Solutions in Brighouse. He does installations for custom car companies. I'll let you know how it goes. Whereabouts are you?

Cheers pal,

I’m over the hill near Silsden, work over in Birstall so it’s a hop n skip to Brig!

If you get chance to do the photos and post that would be great.

Cheers

Will do. Should be ready Thursday or Friday.
