I currently have a Kenwod head unit with preamp outputs for front and rear. I also have 2 Infinity 10" subs 250 W each @ 4 ohms. I was curious what amp I should get and how I would connect it to power the subs as well as the front and rear speakers. I was also looking to keep the price down. Thanks for the help.
Your best bet is a 5 channel amplifier for the budget minded consumer. Your not going to get high fidelity with a 5 channel amplifier but it will power the system moderately. Almost all manufacturer's have 5 channel amps in their product line. The final decision will be how much money you want to spend on an amplifier and I would wire the subs in parallel to get the most out of the sub channel on the amp.

Thanks for the info. I'll check on one of those.
what about using 2 2 channel amps. One for the subs and the other for both the front and rear speakers?
You loose fade by doing this and also the clarity of a 2 chanel amp is not as good as a 4 channel amp.

You could do that, but as jeff said, you'll lose SQ. The lower the impedence the lower the damping factor. However, you could use resistors or l-pads to set you your rear fill. Its just all a matter of how much money you want to spend. Besides, you can get the same version of the 2 channel amp in a 4 channel version for just a little bit more from a lot of manufacturers. And if do get a 5 channel amp, make sure your sub channel is stable at 2 ohm mono before wiring your subs in parallel. Otherwise, get 2 4 channel amps so you can maximize the effeciencly of your subs (2 4 Ohm loads for 2 bridged channels of a 4 channel amp, 4 channels for front and rear)
