excellent quality

The following review is for 40CSS684, which is a part of the bundle you are viewing.

Solid sturdy speakers, good sound quality. Deep bass and crisp highs.

Love The Kickers!

The following review is for 40CSS684, which is a part of the bundle you are viewing.

I bought the Kicker 40CSS684 Component Speaker System for my 2002 Miata. I needed the high wattage because I had an 80watt-per-channel Pyle radio - which exceeded the EOM speakers' ratings.

Pros: The crossover box fit nicely behind the in-door mid-range speaker mounts...the speakers perform very well and are a vast improvement from the originals.

Cons: I had to trim the tweeters a bit (with a Dremel tool) to make them fit the tweeter housings...but no degradation resulted.

HIGHLY RECOMMENDED.

Overall pretty good

The following review is for 40CSS684, which is a part of the bundle you are viewing.

I like the bass that comes from these speakers. They are overall pretty good. My only dislike would be the highs. About 40% of the time the highs are too piercing.

If you can I would recommend the KS series, or the KS series tweeters. These are larger and silk instead of the titanium dome. They also sound much nicer. Just a though.

If installing in a 2010-2013 Mazda3, you'll need spacers in the front. The back will drop right in.

Oh, and these two videos make a big difference in sound quality:
