2 Outputs for 3 Inputs Sorry folks,
Probably a stupid question. I currently have a HU with two preouts on the back (front/rear). I want to run 4 speakers with a four channel amp (fronts and sails), and from what I could tell, there were two inputs on it (front/rear). I also want to run a separate amp for the sub. This leaves me short one set of preouts.
What are my options? Should I just chalk it up and buy a new HU with 3 sets of outputs? I'd rather not, but I'd be willing to entertain the idea provided I could find one that doesn't break the bank...
Thanks for any input.

you could buy a new H/U or get a splitter for your rca's. My H/U has front/rear and sub out, so 3 sets. But i'm running 6 speakers on a 6 channel amp, plus an amp for the sub. What I did was
Run the front rca's to the front input on the amp.
I used 2 Y-splitters for the rear. Basically they are RCA's that have 1 female input and 2 male outputs each. So for the rear I end up with 2 rights and 2 lefts(rear) to plug into the amp.
Then one set of RCA's going to the sub amp.
These arn't the ones i'm using but just thought I would give you a picture.

I would use a splitter for the rear outputs on your stereo when you get the sub amp. That way you retain front/rear fading. Also make sure you get a sub amp with a low-pass crossover. You don't want midbass notes trying to play out of a sub. I'm not sure if amps exist without crossovers now... but anyway...

Thanks for the input guys...I had thought about doing a splitter, but was unsure of the sound quality after doing so. Sounds like it won't be an issue. I think I'll stick with my Sony POS receiver for now...it at least matches the interior.
Get an Audio Control 3XS x-over. That will solve your problems. Or just get any electronic x-over that has FF/RR inputs, as most likley it has a 3rd sub output that is summed from the FF/RR inputs
