Aftermarket Speakers on Stock JBL Unit

[LUVLEXUS101]

I know this is the camry forum but no one really visits the sienna forum so im posting this here....

I blew my dads stock jbl speaker in his 2002 sienna, the dealership wants something like 300 bucks for a single one. So instead of getting that I figured I would go with this:

and just transplant the subs, only problem I see is the difference in resistance, the new speakers are 4 ohm and the old ones were 2 ohm, will this be a big problem or could I balance it out with the fade controls?

them are some pretty nice speakers. im assuming he has an amp to power them? if not go with the cheaper polks the db651.

Ah, I looked at the 651's, I was also wondering if I shoud replace the jbl bass component with another component or if a coaxial would work as well. Only reason I was going with the 6501's instead of the 651's

personally i debated the same thing and i went with the db651's in my 98 camry and i love them. they are so crisp and they do get pretty loud for running off the headunit though im going to get an amp soon. Does this car have stock tweeters if not youre gonna have to mod the door to fit the 6501 tweeter. Id just go with the 651 they sound great
