amplifying speakers (dilemma)

[iceberg65 10+ year member]

Ok so my local Visions store is having a boxing day sale selling this amp.http://visions.ca/catalogue/category/Details.aspx?categoryId=50&productId=2386&menuId=1&parentId1=49&parentId2=''&parentId3=''&menuLevel=2

i am looking to amplify my speakers

Infinity reference 5X7's rated for 60w rms (front)

RCA 5X7's rated for 120 rms (back) and i feel that this is over rated as RCA dont really do much with car audio.

both sets are rated at 4ohm resistance.

I want to get 50-60w rms to all the speakers. I dont care about balance but I want fade control still, my deck has front rear and sub preouts.

With this amp is says that it puts out 50WX2 @ 4ohms or 100wX2 @ 2ohms

my question is:

Should i wire the speakers at a 2 ohm load off one amp running the rca from one front and one rear preout to maintain my fade.

OR

​

should i get two of the same amp and wire all the speakers to 50w at a 4 ohm load.

OR

should i just try to get a 4 ch amp. such as this one.

Cost is a factor as i am a student, but if the sound quality is going to be significantly improved by running 4 ohms rather then 2 i would be willing to spend extra.

i prefer 4 channel amp but lets see what the gurus say

If sound quality is a concern, I'd skip the rears and just go with the fronts.

here are what the costs would be.

one 2 ch.

$82.68

two 2 ch.

$165 Plus a RCA Wire.

the 4 channel would also be the easiest to install

4 ch

178.08 plus an RCA Wire. (10w less per channel too)

and i need a roll of speaker wire regardless.

that could work. save wiring time too, I gotta remove a lot of paneling to get to my rear speakers. Im mostly concerned bout the difference between 2 ohm and 4 ohm loads in a speaker.

id get a 4 channel amp, maybe 50rms X 4.

ok so i think im gonna look to see if there are any great deals on a 4 ch amp, i know a guy that works there so i might get lucky. If it comes down to it I wont be disapointed with the rockford amp powering just my fronts.

But i still havnt heard any opinions about running the speakers at a 2 ohm load

id take out the rears and sell them. sound terrible.

thx for the opinion but thats not really what I'm asking. I have no intention of removing any speakers. And even if i sold em, I would get next to nothing for a used set of rear speakers by a company thats not known for car audio

I feel that the rears sound fine. they are a vast improvement over the stockers and they were cost effective. I'm running a HPF so they don't get any deep bass (that goes to the type R) and haven't been distorting at all. Off the stock head unit they are keeping up with the infinities but don't sound as crisp. still fills in the rear nicely tho.

the bass should seem like it's coming from the front anyway, rear fill just pulls the soundstage back, i will never use rearfill again.
