Our take on the PowerBass L2-6C

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. Finding 2-ohm replacement speakers has always been a problem. Until now, that is....

Replacement component 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. Finding 2-ohm replacement speakers has always been a problem. Until now, that is....

These specially designed PowerBass L Series 2-ohm speakers will make the most of your factory power. Install these L2-6C 6-1/2" component speakers, 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/carbon fiber woofers and butyl rubber surrounds deliver satisfying low-frequency and midrange performance while shrugging off the extreme temperatures in your car doors. The separate 1" aluminum alloy dome tweeters bring the high range to life with the crisp detail that's been missing from your factory sound. PowerBass includes compact 2-way crossovers that distribute the highs and lows to the proper speakers.

Note: PowerBass designed these speakers for use with a 2-ohm factory system. Call an advisor to confirm compatibility with your vehicle.

Good for what they're intended for ...

Richard from Sandown, NH on 8/20/2018

2018 Toyota Tacoma
Crutchfield Customer Review (What's this?)

I ordered these speakers following a recommendation from a Crutchfield Advisor. They're good for what they are, 2 ohm speakers that are intended as an upgrade to crappy factory speakers with a factory system that is designed for 2 ohm speakers without losing significant volume capacity by replacing the factory speakers with 4 ohm speakers. The PowerBass speakers did provide a significant overall improvement that most listeners would be thrilled with. However, for my situation - improving the quality of sound in a 2018 Tacoma with the JBL 2 ohm audio system (with stock speakers that JBL should be ashamed of), the PowerBass speakers fell short of my expectations. Through hours of research on my own, I found that I could do much better by installing JBL Stadium GTO960C speakers in the front, and JBL GTO620 speakers in the rear. The JBLs are 2.5 ohm speakers, which means the loss in volume was acceptably low. Also, for those considering to replace the factory speakers in a 2016+ Tacoma with the JBL system, be aware that the frequencies sent to the front door speakers are filtered and usable by only a woofer. If you attach the crossovers that come with either the PowerBass or JBL speakers to the factory speaker connector, and then connect a tweeter to the crossover, the tweeter won't work. You need to either replace the vehicle stock tweeters or run new wires from the stock tweeters to the location where you intend to mount the new tweeters; I chose the latter.

Pros: Significant improvement over factory speakers on 2 ohm systems


Once EQ'ed excellent sounding speakers

Winn from Hallsville, TX on 6/24/2018

Crutchfield Customer Review (What's this?)

These are great sounding speakers for the price! The instructions from Crutchfield to complete the installation were spot on. One of the tweeters was bad. However, it was easy to exchange the defective tweeter. At first I was "moderately" satisfied with the improved sound over my factory speakers. Once I figured out how to custom EQ (not the apple presets) my songs through iTunes and then sync the custom EQ settings to Apple Music on my iPhone I became "extremely" satisfied with the sound of these speakers.

Pros: Great sound for the price. Installation instructions from Crutchfield were spot on.

Cons: One tweeter was bad but replacement was hassle free. Before I figured out how to custom EQ my songs on Apple Music the speakers were a moderate improvement over my factory speakers.

Great sound quality for 2 ohm speakers

James from Cary, NC on 6/11/2018

2007 Toyota RAV4
Crutchfield Customer Review (What's this?)

They sound great. Really a huge improvement over the factory JBL paper speakers that came with my 2007 RAV4. The mounting kit that came with these for the tweeters was not good, I had to use some of my own leftover pieces from my garage and drill holes in a thin strip of pliable metal to mount them. The crossover in each door is pretty big, about 3x5 inches, it was a little difficult getting that to fit properly on the door. Also note that these are not compatible with the Toyota JBl 2ohm amp due to the fact that there is a crossover in the JBL amp that is different than the signals that these speakers get from the PowerBass crossover. You can't just plug the speaker wires from the front speakers into the new ones.

Pros: Sound quality, price

Cons: Tweeter mounting kit, external crossovers

Better-than-factory replacement

Sound great from my blown Bose in my G35



Awesome sound for the money.

Wyatt from Livingston, TX on 8/11/2017

2012 Ram 1500
Crutchfield Customer Review (What's this?)

Right out of the box, these are the best sounding speakers I have ever installed in anything. Warm, rich, smooth and very accurate. Lows are low, highs are clear and bright. If you have a 2 ohm capable system, these will bring it to life, and don't let anyone tell you 4 ohms sounds better. These speakers are awesome. I cant wait to hear what they sound like when they loosen up a little.

Pros: Price, Performance

Cons: Basket is a little large making for a tricky install, but worth every min.

Product Research


Application: On their website, PowerBass notes the L-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.

Woofer Size Classification Note: Some manufacturers, including PowerBass, call this size speaker a 6-1/2". Because it requires a larger cutout than a standard 6-1/2" speaker, Crutchfield has traditionally referred to this size woofer as a 6-3/4". Please enter your vehicle information to confirm fit.

Tweeter Mounting: The tweeters can be surface or flush mounted using the included adapters. The tweeters are shipped in the flush mount housings and the angled surface mount housings are included. The back of the flush mount housing and the top of the angled surface mount housing combine to create the (non-angled) surface mount housing. Once installed in any of the housings, the tweeter will pivot slightly to optimize imaging.
