Need some suggestion about the stereo setup

[corolla04S-TN]

Hello, I bought a Infinity 2-Channel Amplifier (7520A), it Delivers 97 watts RMS power per channel at 4 ohms or 283 watts RMS power bridged. I don't know if I use this for a sub only better or just for my speakers is better. if I use this amp for my four speakers, I will sacrify the fade in order to do that, and without a sub. But if I use the amp for a sub and front speaker, I don't know if it good or not.
And here are some question:
1. if I use it for 4 speakers, what will the output power be for each speaker?
2. if I use it for a sub and two front speakers, also what the power will be for my speaker and sub, will the power for the sub be 283 watts RMS (bridged)?
3. or this amp is simply good for sub, and I need to buy one more amp? if so, can you recommend some, because I have no idea what is good, some have high power but low price, and people tell me that these kind of amps are not good, I don't know, need some help!!!!!!!
my front speaker is alpine, and woofer is Kendwood. I will choose a MTX sub later, not too much power needed though.

thx

Welcome to ToyotanNation

What are the model of your alpine speakers? And what is the model of the Kenwood sub?

If your front speakers can handle that amount of power 97-125 watts RMS than you can run it to those two speakers. Or if your sub can handle 300 watts rms you can use it to power your sub, not both though.

What model Kenwood sub do you have and do you know if it is a 4 ohm, dual 4 ohm, dual 2 ohm (DVC), etc?

Front : alpine SPS-170A 6.5" 2 way RMS 40
rear: Kenwood KFC-6969IE 6"x9" 3 way RMS 50

And I am trying to buy a MTX sub later, not too much power though.

you said I can't do both speaker and sub, why? I saw the guide come with it, it shows you can connect two speakers and bridge one for sub in the same time.

If you had a 4 channel amp then I can see you doing that but I've never seen anyone wire an amp the way you're talking about. It might be able to be done, I wouldn't do it though.

I bought the Pioneer DEH-P6600 In-dash CD Receiver, do you guys think that I need to buy a amp or just fine with this receiver. And also if I need to buy one, what is the nice one but not too much money though? I mean 4 channels. one more thing, if I connect the sub to my amp, do I connect with speak wires or other kind of wire, like more bigger?

For the sub to amp you use speaker wire.

Since you only have one amp, use it for the sub(s) and run the speakers off the headunit for now. If you want to upgrade to an external amp in the future get an amp that is rated for 50 watts rms X 4.

To connect the sub amp to the headunit use RCA cables. For speaker wire to the sub use at least 14-16 ga. 12 ga. will be more than enough.
