One reproduction combination speaker with tweeters, 4 Ohm, 20 watt. These speakers have been custom-manufactured to replicate original Volvo-supplied low-profile speakers. We requested that the manufacturer add tweeters to the speakers. With correct mounting-hole spacing to fit the original-style mounting bracket, using all 4 mounting bolts for proper sound delivery. The original speaker covers will cover these speakers neatly.
After 30 years in service, it may be a good time now to install properly made replacement speakers into the front doors and improve your Volvo's original stereo sound quality.
