i have upgraded my front and rear speakers. should i go with a 2 or 4 channel amp to power them? the front speakers are infinity 6.5" with 75 watts RMS and 275 max. the rear are 6 x 9's with 100 RMS and 300 max. if i'm correct, the main thing i would lose if i go with a 2 channel amp is the ability to control the balance? or should i go with the 4 channel amp? what are the pros and cons and what do you recommend?

i also would like some recommendations of amps for under $200. thanks guys.

If you gonna add a sub or plan to add one go with a 2 channel amp and let the HU power the rear.
I would not recommend you to use a 2 channel amp to power 4 speakers and bridging your speakers together. The reason why is because in most cases the rear speakers are more powerful than the fronts. If you bridge it the front speakers will start to clip while the rear speakers will still be asking for more power.

If not go with a good 4 channel one.

bigger 2ch for the fronts, smaller one for the rears. staging and imaging are important.

there's different ways you can hook up a second amp. the most common would be running it thru a distribution block or if you have a cap, you can run the power to both amps by tapping from the cap's positive terminal back to the amps!

Go with a 4 gauge power wire from the battery to the distro block in the trunk. Then 8 gauge from the distro block to each amp. Much easier and cleaner to do than to run 2 4gauge wire from the battery to the trunk.
