I know this is an old one but I do have a few questions from an actual user. Basically I need to know what I've got here, should I go with a GT2200? I have a GT2125 and two G3 12" 2-ohm (dual 4) subs. I'm thinking of going to a GT2200, what exactly made you stray from using the GT2200 on your bass? And what made you say you've heard better amps? Isn't it impossible to compare an amp to another if it's powering a different subwoofer, not to mention using a different source unit?
PS- My stuff's not even hooked up, it's all on a shelf waiting to go into a '06 Jetta.
To answer your question.....I would say with two subs I would absolutely go for the 2200 or better the 2300! In my situation I was referring to the fact I hated to waste the beautiful power from the big two channel on a sub vs. midbass etc.... My sub did not require a ton of power and I love extra juice to my components. It was all about my particular situation vs. ability of the amp.
I still stand by these amps as a phenomenal amount of super clean power at a great price!
