Fry's has an Infinity mono amplifier with a 12" infinity sub, both from the reference series, for $100 for the package. I have all Infinity in my car and I am extremely happy with the sound quality. Just thought I would give everyone a heads up.
i really like the infinity kappa speakers....however i have had bad experience with there subs. i ran a 500watt amp and met the rms on 1 i used to have a few years ago. The sub was a 1k watt peak sub. I blew 2 seperate ones and was not even running that much power to them. I may have had a bad 2 seperate batches haha....
