only connect via pasive crossovers ... other connections put your head unit and speakers at risk (will certainly have the potential to seriously shorten the power amp stages life inthe head unit)

If using passive crossovers, then consider matched components.

Before doing this upgrade power and speaker cable..the volvo stuff is junk that will hamper the sonic performance of any head unit.

And i am not talking about mega multi amp stuff here...just your basic head unit.

essentially sort out the basics prior to geting onto the fancy stuff, oh and CHECK that the impedance of an y speakers you connect match your head unit...some 940's at any rate arnt fitted with standard impedance speakers and featured band pass filters in the stock stereo's to compansate for speaker characteristics.

If you want further info email me off list and i will explain..typed it in too many times in here, i will do a doc and email it back...

I had the same problem when I installed a Blaupunkt in my 94 wagon with 6 speaker system. Called Crutchfield to ask them what to do and they said just splice the dash speakers into the front door speakers. Did that and have had no problems.

On the rivets, just drill them. The hole is appox 1/8", so use about a 3/16" drill and go slowly. The rivets are alum, so all you have to do is drill the "head" off the rivet body. Very easy to do. Use a sharp drill bit, as the rivet may spin in the hole.
