Upgrading stock 6 speakers in Lease

[guitarx9002]

Yep, I have them in my dash. They blow the kicker 3.5" speakers away! Tweeter is much better than the kickers.
Others say you can add "bass blockers" so they do not overpower the door speakers because the factory dash 3.5 speakers are only 2 ohm. I have an amp powering my door component speakers, and the radio powering the JL dash speakers, so I do nit have that problem.
Crutchfield is the best place to buy radios or speakers from, because they dont charge for speaker adaptors or radio harnesses.

I am leaving everything else stock in the truck. Do you think I am going to have a problem with these tweeters without the bass blockers or using an amp? Thx!

The JL 3.5" speakers are coaxial, they have a woofer and a tweeter. The bass blocker is used for the woofer. It is so small and cant move much. The bass blocker keeps the woofer from bottoming out.
The bass blockers are 600hz and can be bought on ebay for a few bucks. They get wired in before the speaker connections.
