Question

In car audio, which would be better; a subwoofer with 8 ohms or 4 ohms?

Answer 1

its on the setup with 8ohm subs you would most likely need 2 woofers

Answer 2

the lower the ohm.'s in a subwoofer determines the "how hard does it hit" so the lower the louder bass... but with higher ohms such as the 8 you are talking about will more than likely catch some type or treble (you will here the song ((voice))) but you can always wire down subs to get lowers ohms you just have to know how.

Answer 3

consider ohms law.  I=v/r  the voltage in this instance is a constant. 4 ohm is going to experiance twice the current.  Should be built for that hopefully.  The best subs will be able to deal with a high current load and not tear when you overload it. (as you will)  if your amp expects 8 ohm load and it drives into 4 ohm... your amp melts. planning  ARE WE?  there are 2 ohm subs. subs reactivitity can be more important than base watts...  deliver the actual sounds requested or muddy it all up since the voice coil cant react fast enough under that load... or you burn the speaker and the amp, possible the car. Dedicated amp for the subs and as well  the base? think about that.  And put rubber grommets on your d**n liscense plate. I tire of hearing the rattle.

Answer 4

Provided the amp is designed to work into either load, there's no difference at all.
