Upgraded Subwoofers...no sound from front doors speakers. Help!?!

I upgraded the Basic Subwoofers in my car to HK Logic 7 Subs. I was able to get them out of a totaled 335xi. I have the basic sounds system, so no amp to being with. Now my front door speakers have no sound. I'm thinking I need a bit more power for the front door speakers now because these subs are more powerful.

So without sounding stupid (although I may already), what amp would you suggest? I have (4) Kicker CS4 4" speakers and now (2) Logic 7 subwoofers.

How did you wire the subs?

Depending on how you wire the speakers, the impedance will chance which will ultimately affect the power the speaker sees.

You may have also dropped the impedance to a point where the OEM system is not stable and it is not able to provide power.

I don't know the specs of the Kicker speakers you've got there but the OEM L7 woofers are 70W @ 4 ohms. I've run 100W @ 4ohms to the L7 woofers and they are fine.
