hello, i've already questioned this to other thread but no answers were made.

anyways, here is my question if anyone could answer..

i'm planning to buy an amp for my 4 channel speakers..

all of 4 speakers are 50 watts RMS and 250 peak power.

i've researched some amps for 4 channel but.. if the amp supports any rms over 50watts, can i use it? like 70watts RMS X 4

or do i have to get an exact rms support which is 50 watts? (50watts RMS x 4)

thanks

 

you can get any amp, you dont have to match RMS wattage

 

Keep in mind you are better off using an amp with too much power and adjusting the sensetivity. Not enough power and you will be replacing speakers.

 

alrighty

 

Wait a minute. If you are not putting enough power to your speakers it could harm them?

 

yes, running very low under the RMS wattage of the speaker can be harmful, but if its close theres nothing to worry about

 

Sorry for hijacking the thread again but if you buy one that was a higher RMS rating than your speakers do you can always turn it down correct?

 

correct

 

hey guys, i got an amp which is 75w rms x 4 ch for my speakers.

i went to circuit city to install it but they said the headunit only supports 2 channel amp.. but i'm hearing from all 4 speakers.. it didn't make sense to me.
can someone explain why they can't install the amp?

my current head unit is Pioneer DEH-1900
here's the specification.

when you go down the page.. where it saids..
Audio Features
RCA Preouts ------- 1 pair (rear)

RCA Preouts.. do i need 2 pairs of RCA?
or is that pair of RCA only supports 2 channel?

confused o_O

 

EDIT: Seems like you need an extra RCA pre out for your 2nd pair of speakers. Maybe time for a new head unit?

 

o man.. new head unit??
should that be my final solution?

 

As far as I know you need a pair of RCAs for 2 speakers. 2 channels, 2 cables, thusly stereo sound. I doubt there's some sort of splitter to allow for 4 speakers.

One idea though would be to just power your front speaker with your amp, and then just plug your rear speakers into your headunit.

I've read a lot that rear sound stage actually hurts the front sound stage in many cases. But then again you're never gonna sit in the back of your car and at least your friends who do will have some kind of sound.

If you go this route you may want to just get a 2ch amp instead of your 4ch amp.

I've been known to be wrong before though <_<

Make sure to research more or wait for some more opinions.

 

no no, you just use a "y" connector and input that into the amp. OR the amp itself may have a 2 or 4 channel input option. that is so you dont have to use the "y" connector.

 

i'll just get a new headunit. makes me much easier

thank you for the replies.

 

Or you can just connect 2 line out converters. one for the fronts, and one for the rears, then just plug the rcas into the converters. It's cake and should only cost $40-$50
