Great speaker

Bought these for my wife's car, because the original ones were old. Now it sounds great, the clarity is wonderful and you can't beat the price. Plus installation was easy.

They are ok.

There are ok to replace busted speakers but these get distorted at high volume.

Nice Speakers

I have two pairs of these Kenwood 6.5" Sport Series speakers and I'm running them off of a Pioneer head unit. They sound really good for the money, even though they are only 30 watts rms apiece. I would recommend them if you are building a system on a budget.

Good speakers

Great speakers, the mounts that were sold with them did not fit my Prius as the site said they would though, so I had to do some engineering to get them on. Work great and sound awesome though.

Kenwood speakers

These fit my front truck doors and sound amazing. I’m getting another set of these for the back doors soon. Using a pioneer head unit they sound amazing. Nice and clear and loud.

Good replacement for factory speakers

These speakers sound good in my Jeep JK. Good highs and nice midbass. Have it hooked up to a Pioneer radio and it definitely sounds better than factory. If your on a budget, these speakers wont disappoint you.

Great company! Better than Amazon

Sonic had better prices than Amazon and unlike Amazon, I was able to find the exact right product for my car!

They will be my go-to from now on.

Great basic upgrade over OE Speakers

Great speakers for the money compared to the paper speakers with tiny magnets that come in a Rav4. Ohms aren't correct, but you just turn the dial up in the factory head unit.

Great speakers for a stock upgrade on a budget!

I’ve used these speakers in two of my vehicles, and would recommend them for a quick and quality sound upgrade to replace stock car speakers without a more modern audio package. I replaced all 4 of my door speakers with these, and once they break in, provide a clear and clean audio experience.

My reason for 4 stars is that they don’t have as much as a lower-mid range response I was hoping for, however, they perform much better than I had anticipated, and were very affordable.

Great for the money

Can't go wrong with these speakers. I'm pushing about 15w over the rated RMS to each speaker and they take it excellent. Sound is loud, crisp and excellent. The bass is lacking a little, but for the money they produce above average sound.

Very good for the price

These are some really good sounding speakers for the price, I got them on the black Friday sale and I do not regret getting them. They sound better than the pioneers that came with the truck. Good speakers!
