base stereo BADLY needs EQ pre-amp

Hi Mwhit02,

With 4 speakers and a 2 channel amp, how's it all hooked up? Are you running just the door spkrs and dash tweeters off of the head unit running into the power amp input? 9 watts is 6 volts AC into 4 ohms, so 6 volts should be more than enough to get your power amp into clipping with nominal level settings on the amplifier input level control.
I'm not sure how you've got it all connected. Also check the polarity of the + and - connections of all your speakers if you're lacking bass.
Oh, OK now I know what a Polk MM6501 is.
