Im pretty much audio illiterate so id like some recommendations from you guys on to what amp i should run. The sub is an infinity kappa 10" in sealed box. Its an older Kappa series (the green-ish blue). I got for a great price.
Ive heard compared to the current line, the older infinity's hit harder. Has anyone had any experience with them?

I havent purchased an amp yet but im trying to narrow it down to a few choices. Feel free to suggest other ones in about the same price range as well.

Ideally id like to stay with the pioneer amps to match my headunit, but that probably doesnt matter does it.
The PIONEER GMX922 is 300watts RMS, while my sub is 275rms, Ive heard the pioneers are also overrated a bit.
The pioneer GM-X632 is 150watts RMS, Will this be sufficient to push the sub at a decent level?

In the end, Im looking for clear, tight bass to complement my highs.

Thanks.
