rear speakers

i have a ida-x200 connected to a eqs746. i just hooked up some new RCA's to my 4-channel amp. when i put the master volume all way down on the eqs746, i still hear music playing from my rear speakers. on the headunit, i put the volume at 75%. and when i turn up the master volume it sounds fine but only the right front speaker works and all the rears, but no sound from the left front speaker. i know all my speakers are fine and not blown for sure. and all rca's are on the opposite side of the power wire going to the battery. my 4-channel amp is in the trunk, and the RCA's are under the subwoofer box. will it effect the sound if they are being smashed under something heavy. because my box is pretty heavy. what can be the reason for this? thanks.

At the amp, switch the front left and right patch cords.  Connect the left to the right input of the amp and connect the right cable to the left input jack of the amp.  Which speaker does not play now?

no it wont but I would check you connections on your speaker. and don't uses the factory wire use monster wire.ksaudio

THAT'S helpful... How do you expect that changing the speaker wires will fix his problem? Not to mention the fact that Monster is a complete waste of money...It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

now the left speaker plays and the right doesnt. thanks :].

Put those RCA connections back it their original locations.  Now do the same thing behind your EQ.  Just to the front channels.  Let us know what happens then.

This is called "troubleshooting". He is trying to determine what component in your signal chain is failing. Just follow ALL the steps suggested, in the ORDER suggested, and i am an idiot will help you locate the offending device. He asked you to swap patch cords at the amp - the symptom followed that swap - what this means is that the amplifier (and the speakers, wires and all associated connections) is/are working perfectly, and is/are not the offender(s). If you swap your RCAs at the EQ, as asked, and the symptom does not move, then the RCA's are the weak link. If it does move, then some device further up the signal chain (the deck, interconnects, or the EQ) will be the defect... See how this works? You asked. You are being helped. Sarcasm will get you nothing but nothing - i.e. no help.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

do you know the reason why whenever i put the master volume on the EQ, i still here music from the rear speakers only (low sound)? also i hear a whining sound when i accelerate.

The EQ. 

i never had this problem before though using the EQ.
