Default How Do I Choose Components?

I'm pricing my audion system, to be installed by summer, and i just can't figure all of this amp stuff out....

I'm trying to get these 6 by 9'* for the deck
http://www.pioneerelectronics.com/pe..._35261,00.html
These 5.25'* for the doors
http://www.pioneerelectronics.com/pe..._34895,00.html
and this sub
http://www.pioneerelectronics.com/pe..._38285,00.html

but what amp should i use?
i'm trying to get this for my computer audio system, meaning i will have left and right channels... but that'* where i lose my mind... there are sooo many options, and' i've never seen an amp, they aren't common here in town. i have replaced speakers with stockers, upgrades and put in all new speaker wiring in the 87, but i'm just lost here.... maybe someone knows this stuff better than me...

Wll depending on your headunit i believe your absolute best bet is a 5 channel amp if you have a 4 channel output headunit, if not then a 3 channel will do.. im not REAL eperienced on it but ill try and help....

i'm using a computer as a headunit (which i hope a head unit is like a radio or cd player in the dash...) so i think that'* 2 channel... meaning i'd need a 3 channel amp?

If you're using a computer for all Audio you'll need amps for everything. I'd recomend a nice 4 channel for your speaks, and a nice 2 or 1 channel for the subs if you are getting any.

Each speaker channel should have its own amp channel.

Where you place your sub is placed in relation to center is of no import. You should be cutting all frequencies above about 100Hz. At 100Hz and below you will not be able to tell where the bass is coming from. As far as loading, the sub box should be placed as far away as possible with the speaker facing forward. This prevents the sub from firing into the back of the trunk and bouncing back affecting the next note. Some people like this as it boost the level of the bass, but you are trying to go for purest sound you shouldn't do this. I placed mine in the far back right hand corner (pass side). You will need two amp channels for the sub. This is called bridging and allows you to share the two channels to get more juice without having to buy a big amp. 200 amps is a nice round number to shoot for a decent sub volume. You dont have to get a separate amp for subs, as you could you 2 channels of a 4 chan amp, but using a single amp dedicates all of that amp'* power to the subs, which are power hungy beasts.

So, I can run my audio through this amp:

http://www.pioneerelectronics.com/pe..._38213,00.html

Plug my speakers into it, then go into this amp:

for my 15" 400w Sub?

The top amp is good but you'll need a lil more rms of an amp to push your 15"

I use these in my Blazer

PRS-X320 for the sub

http://www.pioneerelectronics.com/pe..._36992,00.html

PRS-X340 for the mains

http://www.pioneerelectronics.com/pe..._33782,00.html

They sound great, and are of a better quality than the regular Pioneers.

Check ebay you can get them new usually for a decent price.
