i have a regular cab 2000 ford ranger. i recently installed a pioneer deh-3900mp reciever. i have a set of infinity kappa 60.7cs(2ohms) components(2-90RMS/270Peak) waiting to be installed. this is where i need help. since those components run at 2ohms i need a amp to power them. in the future i would like to run a shallow sub behind the seat, so it has to be a 4 channel amp. ive come across 2 models that might work.

Rockford Fosgate Power T4004

25W x 4 @ 4-Ohms RMS

50W x 4 @ 2-Ohms RMS

100W x 4 @ 1-Ohm RMS

100W x 2 @ 4-Ohms bridged RMS

200W x 2 @ 2-Ohms bridged RMS

Rockford Fosgate Punch P450.4

60W x 4 @ 4-Ohms RMS

110W x 4 @ 2-Ohms RMS

225W x 2 @ 4-Ohms bridged RMS

ive seen birth sheets for both and they seem to each average 90-100W x 4 @ 4ohms. which of these would give me more power if i use channels 3 and 4 to power a single subwoofer?

the power line is under rated so you will get more rms than what is listed. check out this link it should help you decide. http://www.rockfordfosgate.com/products/amp_power_output.asp
