    Adding resistor

    I have front speakers 2ohm , I want to add 4ohm tweeters
    the installer man told me that I have 3 choices ,
    wiring them serial
    adding 2ohm resistors to the speakers then wiring them parallel.
    replacing both with a component speakers.

    what do you recommend? I want to keep the sound quality.

    Re: Adding resistor

    well the last one sounds like the best option to me if you are going to do it. you really don't need tweeters if you already have 3 way components. the first option is probably doable but 6 ohms will lose you a lot of power and the second option i would never do. I would not throw a resister in line of a speaker though with out it you would be running 1.33 ohms on your amp which i don't think it is stable at. if you must do this i would just get another tweeter and wire the two in parallel then wire the speaker in with them in series and you would end up with 4 ohms.

    Get components. Done.

    Re: Adding resistor

    adding another tweeter seems good option till I decide which comp to get
    what do you recommend for $200 range comp with Alpine CDA-9887?

    Re: Adding resistor

    Can you actually run a resistor inline with the speaker wire?

    I am sure u could. It would be a waste of poer and not sure how it would sound.

    Re: Adding resistor

    adding a resistor is not the solution, they will heat up and eventually burn out.

    Re: Adding resistor

    If you put a 2ohm resistor in series with a 2ohm speaker running at 40W, the speaker will get approximately 20W and the resistor would disipate the other 20 as heat. So, you would need a resistor rated a good bit higher than 20W. This isn't a good solution.

    If you are going to power the comp set from your HU then probably get a low power set like this:

    Otherwise you should get a amp if you want to run a good set of comps. There are many to choose from in that $200 range. I've heard these are good:

    Re: Adding resistor

    your installer man sounds like an idiot.

    you will need some kind of crossover for the tweeter.. even if it's just a simple capacitor in series... and if you want to be able to adjust the level of the tweeter to the mid you will need what is called an L-pad. Check out partsexpress.

    Re: Adding resistor

    Yes, the resister would dissapate half the load, it would make the amp work harder and lose efficiency for no gain in output.

    Re: Adding resistor

    What are you using to power them? For the crossover?

    Re: Adding resistor

    Very nice deck-power comps.

    Feck that.

    The D-series are pretty cheap right now.

    I have these on my car on deck power, (until tomorrow), and they're pretty solid. I like them better than the $650 Focal 165KFs I sell at work.

    Re: Adding resistor

    Wire up a tweeter with a mid range?

    Good way to toast a tweeter as soon as you play a song.
