I have a P5 and will be putting in some new speakers(boston auc ) and adding a sub. I will be getting an AMP just for the sub and another AMP for the speakers. Now my queston is on the AMP for the speakers. Should I get a 4ch amp to run all the door speaker or just a 2ch AMP to run the front speakers and just use the head unit to run the rear door speakers? Also would a 300w AMP be good enough to push the speakers.

He has a P5. The rear speakers are smaller.
Front = 5x7
Rear = 6.5

Umm...no.
You're not supposed to hear the rear speakers, they act as fill only. When you go to a concert or symphony all the stuff is in front of you right? That's the way you should have it in your car as well.
Here's my answer: if you have a lot of people in the car for road trips, but you don't talk too much on said trips, then get a 4 channel.
If you talk to people in the back just get a 2 channel for the fronts and run the rears off the headunit. Have you ever been in a car and you try to hear what's going on up front but all you hear is the damn rear speakers? I hate that...that's why I just made the fronts powerful enough (120W a side) that if everyone wants to hear music in the car, they will, but if they want to hear what's going on up front and talk we can still have the music play quietly and hear each other fine.
or get a 4-channel amp that will bridge the rear channels and be happy... of course this depends on the power you require for your sub setup. its kind of difficult to find a 75-100W perchannel 4-ch amp that will bridge up to 500W if that is how much you need, but around 300 is not hard to find (thumb)
I would power the fronts off an amp and use the head unit to power the rear speakers. I did that in my sedan and ended up unhooking the rear speakers because they did not sound good at all compared to the focals. I have heard some boston stuff and it to sounds good. You will not like the sound of the rear speakers compared to the bostons. The rear speakers will only hold you down. like servoeyes said the music comes from the front. I only have front speakers and it sounds great. plus when I powered my rear speakers off the deck they could not even handle that very well let alone power from an amp that is powerful enough to power the bostons.
The one option is to get one of the amps they are making specifically for rear fill. JL has the 500/5 that has 100Wrms to the front and 25Wrms for the rear fill and a 250Wrms sub output. That would work if you have a sub that does not require alot of power. I personally have the 300/2 which powers my fronts and that is it. The 2 channel is a little cheaper than the four.
I would not get an amp for the rear speakers. just my advice. listen to some music in your car with the rear speakers up loud, the speakers just as fill, and with the speakers off. That will help you tell some but you have to remember the bostons are going to be way better than the stock speakers. good luck

Thanks for all the replies.
I've got some low end Boston in the back and Boston Pros in the front. My headunit is last years Pioneer 6400, which only has two RCA jacks. So by running my Sub on one jack and my door speakers on the other, I lost my fade front/back. Will this force me to get a 4ch AMP or can I still consider a 2ch AMP?

Sonny,
if you get a 2 channel amp then you will only beable to power the front set of speakers. if you get a 4 channel amp you can use the same signal for the front and rear inputs on the amp (The JL amps you can choose on the amp if you want 2 or 4 channel, not sure about all the brands). If you do that then the only problem is that you lose control over the front to rear fade. But you can still adjust the gain control on the amp to turn down the rears or turn up the fronts. It will just not be as easy since you will have to do it on the amp instead of on the head unit.
If you want control on the head unit then you will have to get a two channel amp and power the rear speakers off the deck or get a new head unit with 3 preamp outputs.

I think the rear speakers are a waste of money and you could save some money be getting the 2ch amp and have the 150Wrms on the front speakers instead of 75Wrms.
That being said, if you really want to run rear speakers I would reccommend the 300/4 for sure. just make sure that the front speakers (hopefully components) you have or buy only need 75Wrms and make sure that the rear speakers that you get can handle that much power.
If you get the set up with the 300/4 and you don like the rear speakers (or blow the stock crap ones) you can always bi amp the front components (if that is an option) or bridge the amp. So the 300/4 has more options.
I Just think it is a waste of money to put 150Wrms of good JL power on some rear fill speakers.
