The following review is for db351, which is a part of the bundle you are viewing.

i bought these speakers for my daughters car to upgrade from the oem junk that was in there.polk audio knows how to make speakers.these speakers sound great.they are marine certified too. polk speakers are very high quality and i think they are some of the best speakers you can buy.sonic electronix is probably the best online place to buy all your audio needs. there prices can,t be beat either! enough said just buy them.

Rocking speakers

The following review is for db351, which is a part of the bundle you are viewing.

Bought these and modified some cans for my Harley. Matched them with a Cerwin Vega Stealth 220, also from Sonic Electronix, and at 95mph, you can still hear everything extremely well over the bike and wind, and the 220 is not pulling any amps. Matter of fact, I fused it at 10 amps no problem. Would recommend both of these products, and they are at a great price also.

FIts in 2013 Kia Optima

The following review is for db351, which is a part of the bundle you are viewing.

Went from the stock 2" paper cone tweeter that sounds really good (well that's what I thought) until is installed these!!

At first my system had a front stage but now I have the front sound stage is all up on the windshield and has very dynamic imaging. even at low volumes I am able it pick up many notes which were never able to be produced on stock 2".


I tuned head unit for the new polks to the song Hotel California and wow I listened to with only my dash speakers for about 30 mins. while I was tweaking my high channel. These speakers really help bridge the gap between my highs and midbass with out going with a 3way component set.

I was stuck between these polks and jbl 3.5 and very happy that I went with these.

Again the fit in 2013 kia optima with only minor altercations!

Great product

The following review is for db351, which is a part of the bundle you are viewing.

Installed these in the dash and rear pillars of my fj cruiser. Almost a direct bolt in with some modifications. Speakers came with bass blockers and can really crank out some ear piercing highs. Way better than the stock speakers. Clean clear sound.

Extremely disappointed...

The following review is for db351, which is a part of the bundle you are viewing.

I bought these speakers to replace the worst speakers i have ever heard in my Toyota FJ Cruiser. Salesman said they would work well. I have owned Polk before in the home... great stuff, still use them. But these are no better than what Toyota shipped. Really crap. Would not recommend them to anyone.

Excellent Quality!

The following review is for db351, which is a part of the bundle you are viewing.

The Polk Audio db351 is the perfect replacement car dashboard speaker. Sound quality is excellent. The speakers came supplied with protective bipolar bass blockers, fitted just perfectly and were very easy to self install.

Excellent Quality

The following review is for db351, which is a part of the bundle you are viewing.

I purchased this speaker specificly for my 2007 Pontiac Grand Prix. It was a replacement for the original center dash speaker. The db351 sounds much better than the original speaker. I recommend this speaker as a replacement, it was a perfect fit.

One of the best value speakers out there!

The following review is for db351, which is a part of the bundle you are viewing.

Bought to replace the overly bright memphis speakers in the dash of my 88 mustang. These are perfect as they are also more efficient. So, they play louder under the same volume. The silk dome tweeters sound refined and mid range is accurate. Overall very pleased with them. Just don't have the tilting feature of the larger speakers.
