hey, i have a pioneer deh-p6400. i just hooked up my ts-a6995 6x9s with out amping them, they are powered by the deck, and i must say, they sound GREAT! now i plan on getting the jensen two channel 500 watt amp model #xa2125. the deck now only gives 20 watts rms or so, the amp will be able to power the speakers pproperly at 80 watts rms. how much of a difference do you think i will see? will i see more base or what? because the highs are loud and clear, but the lows seem slightly week. just looking for your opinions. let me know. thanks.

 

I have the same speakers powered by an older Jensen 200W amp, and the difference is night and day. The bass is a lot better (I also have them enclosed), and mids and highs are nice and clear, not to mention loud.
