    car amp with default speakers?

    Hi

    putting my car pc together this weekend with any luck, replacing my head unit and a bit worried about the fact I still have the speakers that were installed with my car back in 1996.

    If I hook up an amp (no monster just a small one) is there any chance I can blow my speakers? (not through faults just too much power for things meant for a DIN radio)

    sorry such a car audio noob!

    So long as you use your ears and dont be silly, they'll be fine, the speakers will start distorting long before you risk damagingthem... so if you hear them distorting, ease off...

    But! you'll notice a much bigger difference in buying better speakers than you will in amping your factory ones, so think about that as an option

    DIN is a size specification. It has nothing to do with the power output.
    There is a very good chance of blowing those stock speakers. Stock speakers are designed to work with the stock stereo, which is usally very low power output.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

    I would have to agree with Blackrazor, as long as you don't turn them up to the point where they are distorting you should be ok. Just make sure you don't crank it by mistake cuz then you may blow them.

    That being said, you should look into a speaker upgrade anyhow. What's the point of having such a nice in-car entertainment setup (carputer) with crappy sound?

    You actually have more chance blowing expensive speakers with a low powered amp than you have blowing cheap speakers with a high powered amp.

    If you crank up the volume on a low power/quality amp, the signal will start clipping, effectively generating DC current for short periods of time. That's what will kill speakers before anything else.

    But as Bobby says, let your ears tell you when to turn down the volume.

    You need to turn down the amplifier output power and bass dials to zero before you turn it all on, then when running, select a loud track turn your pc volume up to max and turn the amp controls back up in small increments untill you are happy that you have maximum volume and bass without distortion.
    With this setup you won't have to worry about accidentally damaging you speakers.

    Not trying to pick a fight or anything, and i'm not dissing you personally, but thats bollocks. This is the biggest old wives tale ever told in car audio, and it just refuses to die.

    Power is power. Your speaker doesnt care less whether its pure sine wave, square wave, saw wave, whatever wave you so desire, its still power. The speaker dissipates more than 99% of input power as heat... the shape of the wave will affect how nasty it sounds to your ears, but mechanically and thermally the speaker couldnt give two hoots.

    If running your speakers off less power than they are rated to could damage them, then they'd blow up whenever you turned your volume down. If you dont beleive me, go buy a sub rated to handle 100wRMS constant, and then feed it off a 20w amp... then clip the amp as hard as you POSSIBLY can, and the sub wont be bothered in the slightest.

    The ONLY things that can damage a speaker is mechanical overexcursion (caused by too much power for the installation or enclosure) or thermal overload (caused by putting too much power into the coil)

    If you still dont beleive me, have a read of : http://www.bcae1.com/2ltlpwr.htm , he explains it in detail.

    hey yea I meant I would be running them off of an amp *rather* than a DIN radio unit with it's own tiny built in amp. Hence my worry as you point out of possible blow out.

    taking this as a responce to everyone saying it will be ok seems more people think it will be ok.

    As for not getting better speakers only money really I have them if they work that's fine. Saying that I wouldn't mind some better ones (maybe next month..)

    so anyone want to recommend some decent speakers that don't cost the earth?
