whine from amp

Hey all,
Hooked up an amplifier tonite and having some trouble. Its dark now so I thought I'd poke around here until tomorrow.

The problem is a high pitch whine and no output from the sub. If I disconnect the RCA cables from the amp input the whine goes away. I used a line out converter and used this: "Right/Passenger side: Light blue- dark blue + Rear speaker. Tap or splice into those. Driverside kick: tap into yellow - and brown + pair for your hi level Right." from another thread to hook it up. I am 98% sure that everything is hooked up properly.
The amp has a "low pass" setting and when on that the whine goes away but still no speaker response.
I am hoping that I hit the right wires and not anything else, the rear speakers still sound fine.

Just looking for any insight someone may have.
Thanks.

No, I pulled the door speaker today and I had tapped into the wrong wires (smacks forehead). Used a volt meter and got everything straight.

You run your RCAs near from the fuses box. You need to run them away.

I got everything cleaned up and secured tonite.
BUT
When I play with the L & R balance, the sub seems to only be responding to the Left Rear signal. Is this normal? Playing the right side only is just the stock speakers. I've got the amp bridged and both RCA's and hooked up correctly.
Anyone run into this?

if your amp has an output for two subs you need to take the neg from one speaker out and the positive from the other. otherwise you have a mono amp and it will only use the signal from one side

Ya I have it bridged like that but it still pulls from the left side only. Its not that big of a deal, I suppose, though if its wrong I'd like to correct it.
