[QUOTE="keep_hope_alive, post: 8255652, member: 576029"] no such thing as "too powerful of a speaker", it is a common misconception. speakers are loads and are driven by the source. your only concern is the impedance of the existing speakers. you can measure resistance (which will be just lower than nominal impedance). use a Digital Multi-Meter (DMM) to measure resistance of one of the existing speakers (that makes noise, not one that is silent). most speakers are 4 ohm nominal impedance (3.3-3.6 ohms DC resistance). for a head unit upgrade that looks stock with modern features, you can look at Retro Sound. Most Volvo's in that era had easily replaceable radios using mounting kits. Just note that if you ever do replace the radio you may have to rewire to each speaker if the factory radio is a common ground system. [/QUOTE]
