Do you have the yellow wire going to a constant 12v power source? The yellow wire controls the memory of the radio and needs to have 12v going to it at all times, even when the key is taken out of the ignition.
This unit has a separate EQ band for the subwoofer-- you'd connect the sub-out from your CD player to the sub input on the EQ, and the sub-out from the EQ into the input on the sub amp. The "sub" slider would then adjust the sub volume. If your CD player doesn't have a sub-out, and you are just using one of the regular front/rear outputs to feed the sub amp, then the sub volume will follow the other sliders toward the left side of the unit, which is less desirable.
check the rca cables on the back to see if you might have the sub woofer cable in wrong rca spot
this is how it should be wired from your radio front output a set of rca cables go to the radio input of the eq. if you have sub out on radio it will not be used ... eq takes place of it ... turn off subout on radio ... to use eq or preamp you must have at 2 amps 1 for mids and tweets and 1 for subs to work eq right
then from the eq you have another set of rca cables comming from the front output to your mids and tweet amp and then if you dont have a second amp u wont need rear output move over to the suboutput and run a set of rca cables from eq's sub output to sub amp this is how the audio cable section should be connected if you still dont get it to work proper then then it has a electronic issue and need to warranted out if still in warranty or buy new one .... here is a link to the install manual with a wire diagram for repair shop .....http://www.poweracoustik.com/pa2006/manual%20and%20catalog/Processors/PWM-20.pdf
try to use the preset equalizer settings after which you can come back to the parametric equalizer and adjust to your own taste. no problem if you don't connect the subwoofer just make sure you set the hi-pass filter to off so that you will hear the full range to your speakers. but, I advice you to put a subwoofer. There is more dynamics to the lower freqs too. don't adjust the source level if there is no problem. take note the EQ of your head unit is a parametric equalizer. hope this helps while you read about parametric EQs.
Provided the rest of your system is all tuned an in proper shape, and up for the wattts, the best sound to set, starting with the low end...start with is a slightly elevated above zero (about 1/4 up from zero) then slowly gradually slope it down to 1/4 below zero in middle and then back up to 1/4 above at the high end.
The result is a gently curved V type shape.
Now, knock down the highest 2 or 3 freq bands a few clicks till they are just above zero. (1/8).
This is the curve you would shoot for with a real-time analyzer for SQ, punch and clarity.
This setting is a blast,I adapted it from the 10 band "perfect" itunes eq setting. don' t be shy , give it a try... 80hz = (2) or 7 220hz = (0) or 5 470hz = (-1) or 4 1khz = -(-2) or 3 2.2khz= (0) or 5 4.7khz =(2) or 7 12khz= (4) or 9 I have this on my LG tv, however if you need more oomph! to it, simply stick to the same pattern between the two sets above and move each slider up accordingly.
You will need to call the manufacturer, ZAPCO - 209-577-4268, or email them at tech support email@example.com , in order to purchase the part you are missing. It is possibel to hard wire the RCA parts you need and creat a homemade fix, but in all honesty it is not worth it, and it will probably introduce a lot of interference in to the quality of your signal path rendering it a bad option. Give them a call / email. If they will only sell the part to a dealer, call Car Depot @ 615 - 269-8080 and they can have the part purchased and delivered to you for a small fee. Good luck.
What kind of eq is it? First thing I would do is hook up the +12 and GND to the same place the amp is hooked up. I think the eq is having a hard time getting ample current, therefore shutting off all the way when the bass hits. Caps are good, but second battery and battery isolator are far superior.
