how can i add speakers [small 3 in ones] w/o an amp. how bad would it be if i spliced into an existing speaker wire and ran it off of that....sound reduction? poor quality? i just wanted to add small speakers near my center console. any ideas? thanks!

 

Are you talking about adding tweeters or actual speakers? What need would you have for additional mids or highs?

 

if i remember correctly, the current would split evenly between the two speakers. so, if your HU sends 45 watts RMS to a speaker, and you splice, you will have about 22.5 watts per speaker.

so instead of having one at full power, you would have two at half. to low power would cause distortion (?).

IMO, it would be pointless. remove the old and install new, or, install an amp to power the new addition to your system.

just my 1.5 cents.

please correct me, someone, if there is an error in my posting :P

 

The only thing you could do would be to get a Crossover this way you could have the smaller speakers power the highs and the biger ones do the lows.

You could always get a reciver but thouse are expensive.

 

Do NOT splice extra speakers in off of your head unit. I'm not sure if you're familiar with these terms, but a standard speaker runs at 4ohms of resistance. simply splicing in another would change the resistance to 2ohms which will actually generally demand more power from a system, however, a deck does not have the capacity to handle this. you should never run any less than a 4ohm load to a head unit. You may notice that amps will advertise being "1 ohm stable) etc.. this means that it's okay to load them down a bit more.

The best solution for running an additional 3" midrange (I assume you're thinking center channel in your vents or something?) would be to get an amp to run your door speakers off of, then use your deck to power the 3's.

 

Usually with car speakers, they have a 4 ohm load. Depending on how you wire them/spice them together you can either have a 2 ohm or 8 ohm load so power can be doubled or cut in half. You have to make sure the power source can handle the load.

Here is a parallel and series wiring diagram that might help you.
