Default 4 speakers on a 2ch amp

is it possible to do this for a 2 ohm load?
it would be done on the stock position speakers.
im trying to think it through but im too tired to complete the thought process
if i did it with this amp
http://cgi.ebay.com/SONY-XPLOD...wItem
what would each speaker be at?

or should i just get a 4ch amp?

You will lose either fader or balance control depending on which speakers you grouped together. If you ran a pair of 4 ohm speakers in parallel off of each channel, that would put you at 2 ohms.

Don't buy Sony Xplod anything. Don't by anything sold by Walmart.

That amp is a 4 channel.

this is an amp i already have
http://www.mobileonesales.com/product_p/ea2212.htm
would this work if i had 4x4 ohm speakers needing 70 rms each?

even if i get a 4ch amp ill still lose balance/fade control
that's something i dont ever mess with tough

im looking at infinities that are like 60rms and 150max
what's more important to hit rms or max, or both?

Use the amp to drive your front speakers, the amp is 2x50W RMS into 4 ohms, find 50W continuous, [RMS] speakers, although it would drive a set of 60W continuous speakers.
Forget about max powers, deal only in RMS power, there is a saying, "it's better to be overpowered then underpowered" meaning a 2x60W RMS amp driving a set of 50W continuous speakers is better then a 2x50W RMS amp driving 60W continuous speakers, however either way will work, it's not the wattage, but how you use it that counts.

If you want rear speakers, run them off HU power and disable the tweeters or just get mid-range/mid-bass drivers for the rear, as "rear fill". 94

It could, but your sound stage and imaging would suck, and your amp is only 2x70W RMS into 2 ohms. 94

no you dont, put all your money into your front speakers.
in new cars the majority of the sound that you hear comes from your front speakers (and it rightfully should, you dont go to a concert and stand away from the stage the whole time do you?)
lets do an example, if your front speakers are responsible for 80% of your sound and your rears 20%. what is more economically effective, to invest 50% on your fronts and 50% on your rears or 100% on your fronts?
buy a good component setup for the front keep the factory rear spkrs running off the radio, run the front comp set with the 2ch amp, you'll have much better sound imaging this way.
