Quick Amp question - Soundstream VGA320.4
My question is (since my amp experience is low) do I need a head unit with 3 RCA outs for the subs or can I set away with 2 RCA outs? Do amp crossovers usually work for all channels or just in channel pairs?
Could I get away with a single pair of RCA outs and use the pre-amp out on the amp itself to feed the other 2 channels?
Do most amps no-a-days have pre-amp RCA outs like this one?
I'm a little lost

Any advice would be great!
Thanks,
Mike
