where is the power amplifier for the audio system?

Not there either. Took left side panel off and found nothing but rear fuse and relay panel. R

Is this just the regular 2.9n not the T-6 turbo, right? Do you have an e-mail? It's under the right-front seat. I can send you instructions. Zee

Zee, Thx for the response......'99 - 2.9......... rogermattos@optonline.net It is not under the seat, pax or driver. I have instructions for that useless piece of info. Not in trunk, right or left either. Just Got a call from a friend at Volvo. The amp is integrated in the radio. So much for the info in ALLDATA. THX!

Roger, Yes, the "under the seat" info is from alldata. I'm glad you find the right info. I have VIDA on one of my computer that I don't use much anymore and I was going to check on that, I'm too late now...
