About the PowerBass OE-675

Replacement speakers for your 2-ohm factory system
Replacement speakers for your 2-ohm factory system
Some cars use low-impedance speakers to get a little more punch out of the factory radio. If you try to replace these speakers with standard 4-ohm aftermarket speakers, you'll notice a significant loss of volume — never a good thing. These specially designed PowerBass 2-ohm speakers solve that problem and make the most of your factory power. Install these OE-675 6-3/4" car speakers in a 2-ohm factory system, and you'll hear a big improvement in sound quality over your old factory speakers. Plus, their shallow mounting depth ensures they're a fit in a wide variety of vehicles too.
Step up to aftermarket quality
Say goodbye to flimsy factory woofers and whizzer cones. Sturdy yet sensitive polypropylene woofers and butyl rubber surrounds deliver satisfying performance while enduring the extreme temperatures of life in your car doors. The aluminum dome tweeters bring the high range to life with the crisp detail that's been missing from your factory sound, while the Wave Guide Lens guarantees even dispersion.
Note: These speakers won't work with aftermarket car stereos, unless you add a 2-ohm stable outboard amplifier to your system. PowerBass designed these speakers for use with a 2-ohm factory system.

Features
Mounting: In addition to fitting standard 6-1/2 and 4-hole 6-1/2 applications, the OE-675 also has a standard 6-3/4 bolt pattern. However, if mounted in a 6-3/4 location the holes for the smaller pattern create an air leak, which should be sealed using a speaker baffle, or something similar.
Application: On their website, PowerBass notes the 2Ω OE-Series speakers are not designed for use with aftermarket head units or amplifiers. However, if an amplifier is 2Ω stable, with appropriate output power, the speakers are compatible.

These work perfectly! My car has a specific 2 ohm resistant system and these were on the recommended list by Crutchfield. They fit perfect and connected with ease. On top of fitment, they sound great! Provide the base that my car was missing from its stock sound system
