I'm not looking for anything spectacular or expensive. either need 2 2x2 or 1 4x4. found one on crutchfield but I'm sure there is something cheaper and/or local.

need 1 rca cable as well.

suggestions?

what I've found:

CF: Scosche SLC4 $20 http://www.crutchfield.com/p_142SLC4/Scosche-SLC4.html

Amazon: Sosche Loc90 $19 http://www.amazon.com/Scosche-2-Channel-Adjustable-Lineout-Converter/dp/B00009UHRE/ref=sr_1_1?ie=UTF8&s=electronics&qid=1251337336&sr=8-1

Amazon: PAC SNI35 $13 http://www.amazon.com/PAC-SNI35-Adj-Line-Converter/dp/B0002J22AA/ref=sr_1_4?ie=UTF8&s=automotive&qid=1251337336&sr=8-4

the one I have now is shot - keeps cutting in and out. It's a Stinger. I want to be sure to keep away from that brand/result

get 2 of these:

and 1 of these (10 per pack):

solder your speaker wire to the rca plug (+ goes to center, - goes to outer ring) and solder the 10K resistor from positive to negative.

cheap line out converter that works without inducing any noise.

hmmm... maybe. I'm constantly moving/removing my speakers/amp/etc in my truck for hauling stuff/tailgating so I'd be concerned with these getting beat up/solder breaking.

to make sure I have this straight:
+ speaker soldered to outside of the back of the plug
- speaker soldered to inside of the back of the plug
solder a resister from the outside to inside?

I can hook you up with a line level converter for like $4 I think. I will check tomorrow.

This might be one of the more retarded things I've ever heard.

And you'll more than likely destroy your amp if you construct it in this way.

^why? wtf do you think is inside a loc? or do you even know and are just talking out of your ass because you think it sounds ridiculous?

No, I know exactly what I am talking about. The circuit you just suggested will deliver the full signal from the headunit into the inputs of the amp.

no, it won't. it works fine. it just doesn't have any noise suppression.

however, i didn't realize loc's are so cheap now. you are better off just buying one.

Yes, yes it most certainly will. You've left the other resistor you need for the voltage divider out of your circuit. The way you suggested it is simply an extra 10k resistor hung off the output.

It also doesn't take into consideration the input impedance of the target amplifier which could definitely be a problem.

Lastly, at audio frequencies it isn't such a big deal, but hanging a crudely soldered resistor off the outputs will add inductance to the path which will end up in the output as noise.
