I'm looking to install a 4 channel amp and would like to know if the ones below are any good.

A rockford fosgate p4004 (50x4)RMS
A Power Acoustic TS960-4 (100x4)RMS
A Alpine MRV-F540 (80x4)RMS
A Infinity 7541a (111x4)RMS

I'm looking for between 50 and 150 watts a channel and looking to spend under 350 for the Amp....if it's in the area of that I can probably find a deal online to get in my price range. If anyone has anything else I should look at let me know.

I'm going to upgrade the g/f's car (2005 cobalt LS w/ base stereo) and I am looking at simple clean installs. I'm going to be putting a Infinity Basslink in her trunk, and I need to give the corner speakers some more power then. She wants to hear the music with the windows open and 80 mph winds going by. I'd like to put the Amp under a seat 9drivers or passengers) so as to leave as much trunk space as possible.

Any help greatly appreciated.... (How is air flow under a chair? I have amps laying down in my car and with a fan there fine, but there enclosed too, is it open enough under the chair to not use a fan?) Thanks.
