my current setup includes:
-alpine cva-1005 (screen dead just shows the backlight)
-infinity kappa amp (my uncle gave it to me dunno anything about it except its 4 channel)
-infinity kappa 6.5 component in front
-infinity kappa 52.5 coaxial in back
Now that my screen went dead, and i was going to sell my nav unit to get money for different stuff possibly, any suggestions for some components that have better bass response than the kappas? I like the way they sound, tight bass, a little sharp highs so i turned down the treble on my hu, but the bass isn't very full. I know getting a sub would be a good solution, but i'd rather not have a box in the back of my car (merc ml). Is there a set of components that would have a significantly better bass response? i wouldn't want to spend any more than in the 300's.
