Does anyone know a bit about car audio? Well I am putting in a cd setup, maybe with 2x "4 inch Response Mid/Bass 3/4 inch titanium dome tweeter" speakers in the front, in the factory holes, plus "6.5 inch woofer and 1 inch titanium dine tweeter" in the parcel shelf factory holes in the rear, (p. 234 of the Jaycar catalogue) with an Alpine 50x4 head unit. No amp, stacker or subs. Can anyone tell me whether these are like the right speakers for this sorta setup? Thanks.
