Remember guys -
The large spade speaker connection always connects to positive or the + side of your speaker or wiring

Secondly,
Un plug the factory tweeters when you install your upgraded speakers.

Third, never mix two different speakers. Install the JBL pair and don't try one oem and one JBL for comparison.

Speakers will break in after a few days, so I like to not hit them hard with volume for a couple to 3 days. You will find they sound better with time.

Register them asap because anything mass produced can be problematic.

The +/- 3 db switch on the new JBL is optional to your liking either way.
