I am looking for the best budget speakers i can get for my moms car. She wants better sound than the factory bose system in a 02 audi s4. The front are 4" components, however i dound a diy it is fairly easy to put in 5 1/4/ the rears are 6 1/2 coax in the deck. I am going to bypass the factory system/amp all together and run new speaker wires to the hu. the hu is a alpine cda-105 .
So far i found the new mb quart discus series components and mb quart 6 1/2" coax in the rear. for about 100 shipped both sets. or the rockford fosgate prime 5 1/4" components and 6 1/2" . I also found the alpine type s 6 1/2" coax but alpine doesnt have a 5 1/4 type s component. I would be willing to mix and match sets for the best sound. would like speakers with decent midbass, probably not getting a sub. Would prefer a silk tweeter also. I realize my options are slim when just running hu power, is there anything else i should look at? trying to stay under $120 for both.
