Featured review

Sounds great. When i took out the factory speaker, I was like WTF. I couldn't believe how cheaply they were made compared to these. Took me a little time to figure out how to install them, but they sound great. Nice solid install with the adaptors and wiring that were included.

Product Research

Features

Woofer Cones: The Kicker KS Series speakers feature durable polypropylene woofer cones, resistant to moisture and the temperature extremes found in automotive applications.

Dome Tweeters: The ¾" silk dome tweeters provide a smooth high frequency response with a wide dispersion pattern. The tweeters have neodymium magnets.

Mounting: The speaker baskets have multiple mounting holes and are designed to fit a standard 3-hole 6½" applications and Ford's 4-hole 6½" application. With the extended mounting "ears" around the perimeter of the frame, they also fit many 6¾" applications, but a speaker baffle should be used to seal the inner ring of screw holes. Kicker also makes a dedicated 6¾" speaker in this series (item number 20647KSC67) that is often a better fit for those applications. Adapter brackets are also included that are compatible with other factory speaker applications. Please enter your vehicle information to confirm fit.

Q&A

13 questions already asked

Can these be wired a 2 ohm?

[ CHRIS Feb 28, 2023 ]

1 answer

Yes, you can wire a pair of the Kicker 47KSC6504 in parallel to get a 2 ohm impedance.

[ ALLISON Feb 28, 2023 ] Staff

It says these dont fit my crv but the size smaller does. yet the cutout diameter isnt a problem since the 6.5 component set says it fits. Are you sur these wont fit? only .04 mounting height difference which doesnt make much sense since the 5.25 fits. I just dont want to have to fight to get tweeters in the dash corners and i have nowhere to put the crossovers

[ CHRISTOPHER A Nov 05, 2022 ]

We'll need more information about your vehicle (such as year model, speaker package, etc.) to answer this question. We are careful to measure the speakers we carry as well as the vehicles that we deconstruct and research. We also factor in the dimensions of the brackets that we provide to install aftermarket speakers. Sometimes it is possible to install speakers that we state will not fit, but more often our measurements are right on the mark. Please reach out to our advisors via chat or phone at 1-800-324-9695 for in-depth help with this project.

Can I just buy a single one?

[ James Sep 20, 2022 ]

1 answer

Sadly these come in pairs only, James. What I would advise to save the most would be using our outlet stock to your advantage here! If you click on the link for the Kicker KS 6 1/2" speakers below you will see those options below "add to cart" in a yellow box. That means we have outlet stock available! If you do only need a single to replace a damaged speaker, custom center channel, or other single speaker situation you can use our Open Box or Scratch & Dent categories to save you some scratch. The biggest discount goes to the Scratch & Dent section, and both speakers are functional and covered by full factory warranty. That can save you the most if you do have to get a pair and only use a single in your application! https://www.crutchfield.com/p_20647KSC65/Kicker-47KSC6504.html

Do i need an amp or crossovers for this speaker to work?

[ Eli Aug 22, 2022 ]

1 answer

Greetings Eli, and thank you for your question. The Kicker KSC6504 has a crossover built in for the tweeter. You will not need a crossover. This can run off radio/stereo power, but will sound much better with an amplifier.

[ THOMAS Aug 22, 2022 ] Staff

What type of connection do these have? Will I be able to "plug and play?" with my Nissan Murano?

[ Jacob Jul 29, 2022 ]

1 answer

These speakers have female quick slides on the ends of them. It would not be a plug and play connection on your Nissan Murano but we may have an adapter harness for your vehicle. If you give us a call at 800.324.9695 one of our advisors will be happy to help.

[ ARIELLE H Jul 29, 2022 ] Staff

When it says, 100 RMS, does it goes by pair or each??

[ Luis Jul 21, 2021 ]

2 answers

100 Watt RMS per speaker. Peak Wattage is 200.

[ Michael Oct 20, 2021 ]

had these for a almost a year now, recommend 100W each but that is peak, so rated continuous should be about 50

[ D Jul 22, 2021 ]

I plan on installing these into my 2005 Toyota Tundra to replace the old stock jbl stock speakers. Will the stock amp support these?

[ RYDAR Jul 13, 2021 ]

1 answer

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you.

[ KRISTINA Jul 16, 2021 ] Staff

Should I use bass blockers with these?

[ GEOFFREY Jun 29, 2021 ]

I did not. I have zero distortion at high volume levels. Hope this helps

What type of Amp should I get and how would I wire the speakers to it?

[ CODY Apr 01, 2021 ]

AudioControl crisp and clear sound

[ GERARD Apr 01, 2021 ]

I purchased a 4 channel Amp (75 watt per channel) so I could run these speakers (rear door of a Chevy Silverado 4 door). I added the Kicker 6.5" components to the front door. The Amp runs all the door speakers.

[ CHARLES Apr 01, 2021 ]

Can I run these speakers off my 1990 Realistic tape deck? Model 12-1930A

[ ANTHONY E Oct 30, 2020 ]

Yes

[ GERARD Apr 01, 2021 ]

Sure, very good speaker, they sound great in my Ram. Great mid and highs.

[ GERARD Oct 30, 2020 ]

What size wire do you recommend for these speakers?

[ Felipe Aug 04, 2020 ]

1 answer

16 gauge speaker wire will be absolutely fine for these speakers.
