JBL is a solid brand in my opinion, can't go wrong when considering them for a speaker upgrade.

2 ohm speaker with great reviews at a good price
Alex A on May 27, 2016
I read great reviews about this speaker and the three way counterpart. 3way has better high end, 2way has better low end and I was gunning for the low notes here.

Will these speakers work good on a after market amp?
Bighomie on Apr 22, 2016
Best Answer: I'm not sure, as I only have them running through the stock wires and head unit. That said, they are excellent speakers with good power, and I'm sure they will handle the extra power just fine, and as with most aftermarket speakers, certainly would sound even better through an amp.

What does it mean 2 ohm impadence?
i am replaclacing 2 ohm factory speakers!
A shopper on Dec 25, 2015
Best Answer: Impedence must be matched uless you change the source unit (stereo/radio/amplifier)...using a different impedence rated speaker will require different wiring or resistors. Use the same and you will get good sound. I have an entire JBL and Rockford Fosgate system in my Nissan 370Z and i am beyond pleased. Just match the numbers and it will be good to go.

Will these work with the Kenwood eXcelon KDC-X998 Head Unit? Specs on the H/U says it has a 4-8 ohm rating. Will using these cause any real problems since they're 2 ohms?

Is there an installation kit that is available for these speakers?
Tom S on Dec 5, 2014
Best Answer: Hello Tom,

Specific speakers do not have 'installation kits', so we aren't sure what you are referring to. Some vehicles require a Bracket, and that is what you may be referring to. However, JBL sends their speakers with universal speaker adapters, pictured in the link below.
