new guy building a modest system

I did some searching, but mostly found which is better threads and the definitions by KARLEON didnt satisfy me...

I intend to replace all of the audio components in my jeep cherokee (4 speakers, head unit, wiring) and add 2 10" Kicker Comp Subs and an amp.

In my search for an amp i have no brand loyalty or preference but looking at kicker and rockford fosgate right now

#1. Looking at the walls of amps at various stores and online i see MONO, 2 channel, and 4 channel......what is the difference and what are the benefits of each? (do i need a 2 channel amp to run both the speakers and subs or am i way off base)

#2. Peak power each sub is 300W....what limit does that put the power of the amp i choose?

i dont know what i dont know, so any intelligent information is appreciated

 
Peak power isn't the number you want to look at, check for RMS, nominal or constant power. Usually half of peak. From there, best bet is a mono sub amp rated to do twice the RMS rating for each of two subs since the power will be split between each. So in this instance you're probably looking for a 300w RMS amp.

Next up is ohms (resistance) of the subs. Most mono sub amps are optimized to operate at 2 ohms, so you'll want either (2) 4ohm subs with a single voice coil (SVC) or (2) 2ohm Dual VC subs. Either can be wired to make a 2 ohm total resistance.

Now back to the amp - make sure it's rated around 300w @ 2ohms. You can probably get away with 400w w/o any trouble.

Good luck, keep us posted!

Last will be main spks & amp. When choosing the main speakers go listen to them - don't take advice, let your ears decide which ones you like. Then pick a 4 channel amp with appropriate power, probably about 50x4.
