Yeah, I think I'm gonna go ahead and disagree with you there. I know the ZX450 is a nice amp but I just don't think it has enough power to say it "walks all over it". They may be pretty comparable I agree but there is no way it is a better amp, let alone far better than the 340. But I do respect your opinion. Most people don't think Pioneer makes a good amp and that they only make decent headunits. The truth is the PRS line of amps throughout the years are VERY high quality amps. I'm sure the 450 is underrated just like the 340 but I can't see it being THAT underrated.PG ZX450 will walk all over it. I'm not knocking the Pioneer amp, as a friend uses 2 of them and they are nice, but nothing compared to the 450 mentioned a few posts before yours, by me //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
Again, just disagreeing and not trying to bash the PG amp.
