I have a 93 volvo 940 wagon. I would like to upgrade the factory speakers. I am planning on getting an Alpine CDA-9883 HU. I would also like a good amount of bass from the 5-1/4" speakers and am going to use bass blockers on the 4" up front. Any recommendations? Looking for both the 4" and 5-1/4". Budget is around $100 can go more.
