My stock speakers were falling apart so I decided I would replace them and the head unit. It's a Pontiac sunfire. So I got new 4x6's (JVC) for the front doors and 6x9's (kicker) for the back dash. I got a kenwood receiver (can't remember the exact model, but I can post it later if needed) that has ~25w rms. The stock system sounded decent before the speakers went out, and I don't have high expectations, but after replacing the speakers I have no bass. I mean NONE. mids and treble sound fine, and if I crank it way up and pretend a bit I can hear some low notes. my first thought was that I had the polarity backwards. . . on all the speakers. . .because I was an idiot, but I double checked them and it is correct. Any ideas where to look next? Like I said I'm not expecting a lot, but it has less bass than my phone does. Thanks in advance for your opinions/suggestions.
