I have a 15 year old Akai stereo receiver that I may use to drive a SVS sub. It is a 100 watt per side with pre-outs, (I beleive this is what they are called ) they come out and goes back in the rear with Rca's so you can "split" the preamp from amp, I think. Or they may be just to add a external processor ? Can this be bridged to get 200 watt for the sub? The reason I am entertaining this is that I ordered an Adire Rava, it was supposed to ship yesterday, but now is on backorder until mid January and I started to look into getting a SVS 20 or 25 unpowered and use this very nice and powerful Akai amp. Thanks.
