You’d be surprised by how much a good audio system helps improve the quality of time you spend in your car.

These speakers are usually the ones fitted into the doors of most vehicles and the rear deck area (at the base of the rear glass) on sedans.

Just be careful when ordering speakers as some models are sold in a pair, two pairs, or even as single speakers, so you’ll want to pay attention when ordering to avoid any surprises when the speakers arrive.

All aftermarket speakers are designed to be a relatively universal fit for existing or custom applications, but the JBL Club 8620 pair of two-way coaxial speakers are an even better choice thanks to a design that lets them fit 5×7 and 6×8 openings.

The 3-ohm low-impedance design allows the speakers to draw more power and deliver extra punch from the stereo, and the sound is even better when the system is hooked to an outboard amplifier. To capture the high-frequency range, the JBL Club 8620 has an edge-driven PEI to deliver a crisper sound, while the patented Plus One woofer design delivers better mid-bass sound. These speakers are designed perfectly for anyone that wants to get the best value from a set of speakers without sacrificing quality for price.

If you’re looking for great 6×8 speakers with plenty of bang for your buck, Kenwood’s Performance Series speakers are an ideal choice.

What You Need to Know About 6x8 Speakers

The best part about aftermarket 6×8 speakers is that they are designed to be as universal as possible, fitting in factory mounting locations with few, if any, modifications. That being said, you’ll want to double check the dimensions of a particular speaker before ordering it to make sure it will properly fit into your desired mounting locations. Almost all speakers should be sold with the proper mounting hardware and wiring harnesses, but you’ll still want to verify this information before purchasing a set.

How to Replace 6x8 Speakers:

Whether you’re replacing your door speakers or the speakers in the rear deck, this is a fairly easy task for just about anyone. The hardest part of the whole process could be removing the door panels without causing any damage, so try to look for information or videos online to help. Rear deck speakers are usually accessed through the trunk, although some have mounting hardware that requires trim to be removed from the inside of the car.

Once you have access to the speakers, remove and retain the screws holding in the existing speakers, and install the new speakers. If any of the door panel retainer clips break or are damaged, replacements are easy to find online or at your local home improvement store. Some speakers come with wiring harnesses that are compatible with the factory connectors, while others are designed to be more universal and require connectors to be cut off and new wires spliced it. Either way, wiring speakers is also an easy task.

Tips for Choosing the Best Speakers:

As is the case with many aftermarket accessories, you’ll first want to assess your needs before purchasing speakers. If you have a high-end stereo and amp setup, buying better speakers will be best in the long run since they will provide better sound and durability. If you’re just looking to replace blown speakers or add speakers, then you can get away with more of a value-oriented speaker. But if you have a high-quality head unit with an amplifier, then you will obviously want to lean towards performance-oriented speakers.
