Hi all,

Heres the situation. I have a new Sony head unit that has 2 pre outs (Front and Rear/Sub switchable). I currently have 4 speakers and no sub.

I want to get a sub but I'm confused about the amplifier side of things in relation to my head unit.

if I get a 4/3 channel amp for the speakers can I also get a mono amp for the sub? or can I only amplify the front speakers and a sub?

Any help appreciated.

You can split the signal for the fronts with a couple of Y cables then run it into a 4 channel amp as in LF and LR as one pair and RF and RR as another pair. The only real issue with this is you loose your fade ability. Other option is just dont amp the rears and use the factory outputs. Should really only use the rears for a bit of rear fill anyway. The majority of your sound should be in your front components.

Yeah I think I'm going to go for a 4 channel amping the front and sub with the rear running from the head unit. Seems to be the general opiniun from what I can find online.

Yeah, its about the best way to do things on a budget. Being a fellow geek im sure you already know this, but when looking for an amp, look out for the WRMS output, not the marketing BS PMPO.
