say I were to have a 100rms x 2 at 4ohm and I hooked up 2 speakers per channel (if thats possible) would that split into 50rms x 4 at ??ohm?

Thanks

depends.

what is the impeadance of your speakers (4ohms?), and is your amp stable at 1/2 the impeadance of your speakers? if it is, you can wire your speakers in parallel so that you have each pair of speakers on 1 channel of the amp.

if your amp is 100x2 at 4ohms, it might be 200x2 @ 2ohms (so each speaker would still get 100watts), or 150x2..... they only way to kno is to look at the ratings for that amp.

all 4 speakers are 4ohm.. the amp is a Pioneer GM-X1020, i can't find any other specs on it., but 200x2 sounds right.

Each speaker would get 200 watts. Resistors (i.e. speakers) run in parallel recieve the same voltage/current (i.e. watts) as the power source (i.e. amp). The amp puts out 200 watts, so each speaker front/rear would get 200 watts. If the speakers were in series then each would recieve an equal split of the power source (so if there were 2 speakesr, each would get 100 watts, if there were 3, each would get 66.66667 or so watts, etc). The downside to doing this is your amp will be outputting the exact same signal to your fronts as you do your rears. Naturally, you want the rears to provide a more bassy tone and your fronts to give you more highs to enhance front image. Just amp your fronts is what I would do, or get a 4 channel amp if you must.

juniordc2

hmm.. so you're saying I should just amp my speakers in the front and leave the rears alone for the deck to handle?

TexTeg

yes, I think you will like that better. Not to mention, its hella easier to wire.

100x2 at 4ohm.2 4ohms wired parrelell would be 200 watts per channel at 2 ohms.two 4 ohms wired series would be 50 watts per channel.most all amps run 2 ohm stereo.

The more bass you can get up front...the better your stage will sound. Remember, the high hat and kick drum are located in the same place on the stage.

Also, specs on your amp:
100 x 2 @ 4 ohm
150 x 2 @ 2 ohm
300 x 1 @ 4 ohm

stop spreading wrong information. if I have a 1000watt amp, powering 2 subs in parallel, each sub isnt getting 1000watts. it just cant happen. a 1000watt amp isnt gonna make 2000watts. each sub would get 500watts. so in his case each speaker would get 75watts since its 150x2 @ 2ohms.

about the front/rear thing, its all preferance. if you have any kind of staging up front I wouldnt want rear speakers, except for when I have passengers back there. if I have just coaxials in the stock location all around, I would amp them all, since its not like your going for serious SQ in the 1st place, just louder/clearer music. then again, its all personal taste.

Just series the 4 speakers to that 2 channel amp.. it should be fine.. thats how i would do it

TexTeg

Bah, you're right... I was thinking voltage is the same across parallel resistors, but then I forgot to take into account that the current would be halved in this case. My bad.

And I suggested having the rears provide more bassy tones to mix with the sub back there or that woudl be back there. Since bass isn't directional, I wouldn't of thought it would matter all that. But yes, its all personal taste, give different things a try and see what they sound like.

Thanks alot everybody for their help

Normally, I've been able to tell where bass comes from...sometimes it wanders up front, but if install isn't perfect, it's localizable.

This fact is disputed heavily between SQ comp people. Some absolutely swear by having a sub up front, and I think they are correct. Nothing, IMO, is better than having all your speakers in front of you. Again, I'm an SQ nut, so that's how I like my system.
