[Treo is made by Treo only, they make no other brands and are made by no others. Memphis is nothing close to Treo. Nothing wrong with Memphis. I have a Treo SSI 12 in my yukon, no mods to the truck at all, and a Zapco amp that is blown, I am doin over 140s all day every day with nothing tuned. I run the sub till it stinks, shut it off cold and it still plays music like the first day I opened it up. Not many subs do that. They are a great small manufacturer to deal with on a personal level also. The SSI series is far from there competition level subs, but it does what it does.
