just looking @ some stuff on the net...was wondering what the major differance btw the Alpine type r 1242d & the Alpine type r 1222d are other than the ohms and which one is better ?

and how does the ohm make a differance

took a look @ the specs and they look the same...

Thanks.

 

the only difference is how much they will draw from an amp. amps are usually rated @ 2 ohms and 4 ohms. you should choose your subs based on what your amp is best suited for.

 

i have a real old school earthquake amp....2 channel amp....

not sure how many ohms it is rated @.

 

Then you should really find out more about the amp before you decide on any type of sub. Post the model number of the amp, google it, something to find out what it really is.

 

there is no model # on the amp..the cover was painted over when i got it...was told it does 600 wrms.

i can try and post a pic of the amp..however not sure if it will help because the cover is painted.

 

a pick could really help narrow it down. if you dont know about ohms then you should really read up on them. running you subs in series or parralel will change the total ohms aswell. i really really advise you start ready a bit more on this or else you can damage/fry your subs and/or amp.
