So I did have a really nice Kenwood KA6000 (with the rear 200W tag plate) I think it was rated ...45 watts per channel. It was a strong amp with two AR3a 12" woofers. But gone now. So I'm starting a new system that I hope could be similar. Just picked up a Kenwood KT6500 tuner. So starting from there...any recommendations on a good amp? I think the KA3500 maybe?
