i have an 04 ultra and am looking to upgrade my speakers. i have the stock hd head unit and don't plan to change it unless it takes a poop. if i am not mistaken it is a 8ohm unit right? anways my questions deals with the ohms, i am not sure what brand speaker i want, still looking around but does it really make a big difference if i get 4ohm or 8ohm speakers and wire them to the radio for now? i will probably had a amp in the future, one thing at a time.

thanks
kevin

 

Not an expert,but I think you should stick with the same as stock.

 

have fun researching. looking to do the same . watch this forum and you will find good info.

 

Try doing a search here and i'll bet you will find a better explaination.

 

Check to make sure what they are, I was thinking 4 ohm, but if they are 8, I would suggest you stick with 8. You could always get an amp and go 4 and have much better sound.

 

you need 2 ohm speakers i choose boom speakers from harley waiting for spring to listen to them at 70 mph

 

yours is 2004 no idea what impedance newer ones are 2 ohm

 

My 05 I put in Hogtunes speakers & amp about 4 years ago. Still sounding good. Below is a link for there web site which has lots of information.

I installed a Hogtunes amp and speakers in my 07 EGC. Couldn't be easier. These guys supply a top notch kit. Every thing you need is supplied. Even a dumby can do this. Thanks Hog Tunes.

 

2 ohm is need,for stock radio,might as well do the whole thing,if u go with a 4 ohm amp then u can use 4 ohm speakers.
