Great speakers, excellent price!

The following review is for CS-J620, which is a part of the bundle you are viewing.

I looked around at other shallow mount speakers and this was the best price. More like "best bang for the buck" sort of thing. The build quality is excellent. The speaker is not as large as the pioneers I pulled out of the civic but.. the sound is much more accurate, clear, precise. They do have a coated cloth surround, so they're not going to last forever, but for the price, that's fine with me! The old pioneers I took out of the civic were "muddy" sounding even when they were new, lacking midrange and treble clarity. They had bass but no presence or clarity. These JVC's are much more accurate and clear, they don't have a lot of bass, probably because the magnet is smaller. I've also noticed as the speakers have "broken-in" they've become louder with the same volume level. I've seen that happen before with speakers. However, if you're looking for a clean, crisp sound from a shallow mount speaker this is the clear winner! There is mid bass from this speaker, just don't expect subwoofer type bass out of this shallow mount speaker. And the price is the best I've seen out there online. I had a friend who ordered from Sonic, and he liked them so I tried them. It was packed well with packing popcorn all around, packed well!

Excellent Door Speakers, Excellent Price, Fast Shipping!

The following review is for CS-J620, which is a part of the bundle you are viewing.

These sound really good, way, way better than the muddy old dry rotted OEM Honda speakers that came out of my Civic that never really sounded all too good in the first place and now sound like a pack of angry frogs in a lawnmower due to age!
The highs are clean, clear and crisp, mids are very full, warm and clear. Vocals, keyboards and guitars all sound really good, these also give a decent amount of low-end bass that fill the sound spectrum quite well, which is unheard of from most door speakers I've tested or owned, Especially for a pair that unbelievably cost me less than $25!
These can also handle a good amount of volume without distorting!
I was a bit concerned about how these would sound in the highs and midrange since these are 2-way and not 3-way units and were dirt cheap, I thought, sure I'll get what I paid for-junk, but man, I am very impressed and real glad that I chose these JVC's based mostly upon their stated freq. response range, dB output and RMS capability
They sound much better than I ever anticipated and work really well with the new BOSS head unit and new Boss rear 4-way 6x9's that I've also installed. (I didn't get a pair of Boss door speakers to match the rest of the Boss brand setup because Boss doesn't tell you their Freq. Resp. on most of their 6-1/2" speakers and I wanted a pair that could give out some low end bass below 60hz!)
These go down much lower than 60hz and sound a lot better than a far more expensive pair of Kicker brand door speakers I recently installed in my Mrs Buick! I might take the Kickers out and get a second pair of these for her ride!
These are also NOT an ugly designed pair of speakers by themselves, unlike some other pairs that I looked at first that made me think "what were they thinking when they designed these?"
I don't really like the look of the plastic grilles that came with these, and thankfully I don't have to use them, they aren't mesh style "Grilles" and are just the open faced plastic "spider" style rings/covers, Although, the speakers themselves will never be visible behind the OEM door panels built-in mesh grilles in my Civic anyway, but I just thought I would mention it.
FYI!, I do NOT work for these folks at Sonic nor do I personally know anyone here, so with that said;
The price on these was a bit lower here than anywhere else that I could find that sells these online and the shipping fee here was also much cheaper than everyone else online too! And the good folks at SonicElectronix really ARE pros with very fast, hassle-free order processing, handling and shipping out items! These got to me in less than a week (3 or 4 days) and they were packed really well, which is awesome in MY book, and why I have made a few purchases from here over the years for all of my vehicles and for some friends and family members vehicles as well, and why I will continue to buy whatever I need or want for my vehicles to sound great from here!
If you bought your stuff from anywhere else you most likely got ripped off!. I learned the hard way to look here first after getting the shaft from some "scummy" online sellers out there! Always check prices here at Sonic first, I do! :)
And another great thing with shopping HERE is that whenever you look at any product page, say head-units for example, if there is anything else that you would need or should have to either hook it up or install it properly they will show you exactly what you might need on the page of the item your looking at, and it is always a real related item and not just some unrelated junk they want to get rid of like most sites do! I don't know about you, but hat really grinds MY gears when a site shows some totally unrelated items under a "related items" banner!!

It was just what i needed to get the full sound i wanted out of Alpine type s6"x9"3ways and front 4" clarity thanks to the tuning on the amp.i got the highs and to lowes without distortion when i turn it up so the car next to me can hear it to.Great choice if you like Rock music loud.

Replacement speakers

The following review is for CS-J620, which is a part of the bundle you are viewing.

I bought these speakers to replace the rear speakers that are blown in my 2001 honda cr-v. I have the speakers running off the factor radio. The speakers are very clear but not much bass, that's to be expected when your're running after market speakers on a factory radio that's only putting out 4 or 5 watts. Overall for the price these speakers are good they would sound better with an small amp on them. I would definitely recommend these speakers as replacements.

Clean sound

The following review is for CS-J620, which is a part of the bundle you are viewing.

Not wanting to spend a ton of money to replace the speakers in my old truck these were a perfect choice. I chose to replace all 4 speakers to restore OEM quality sound. They produce clear crisp sound at a reasonable volume which is all that I was looking for.
