Can i use a subwoofer crossovers in my car?

Question

Im not ready for an amp so i was wondering if i hook up a low frequency crossover to a subwoofer in the back of my car to the car stereo , will it only play low frequencies? or would it try to sound like regular speakers? Also can this damage my car stereo? thanks

Answer 1

its not really going to do anything you might get a little sound out of it but not enough for you to notice it from the inside of your car. sense all your power from your reciever is going to the door speakers there will be little to non going to the sub and if you do happen to hear enough out of the sub your door speakers are being limited dramatically.

it is easier to wire and easier to control if you buy a small amp and place it in the back along with the sub.

Answer 2

any sub will require an amp because a radios internal amp is not powerful enough to power a sub (it was made to push smaller inside speakers)- you WILL damage the sub and you COULD also damage the radio

the sub will receive a distorted signal and you could fry the radios internal amp

If you send too much power to your sub, you risk damaging it. The cone of the speaker and the mechanical parts that make it move may break under the stress. Surprisingly, too little power can also damage your subwoofer — in fact, it's actually more common than damage caused by overpowering.  

When the volume is turned up and the amp doesn't have enough power, the signal becomes distorted, or "clipped." This distorted signal can cause parts of the speaker to overheat, warp and melt. Not good!

You don't have to match speaker and amp wattages exactly. An amp with a higher output than the speaker's rating won't necessarily damage the speaker — just turn the amp down a bit if you hear distortion from the sub and don't run the speaker at extremely loud volumes for lengthy periods. Likewise, you'll be OK with a lower powered amp if you keep the volume down and don't feed a distorted signal to the sub
