Polk Audio Mobile Monitor 5.25" + 6"x9" Speakers Combo

Great sounding speaker

Overall this speaker has a nice warm sound that gets better and better. I have only had these for a week and they get better bass extension, although it isnt completely needed because I have a sub. I purchased these the 6.5 components, and the 6x9 polks as well they sound great together. I have a 12 inch kicker L7 solobaric and these speakers keep up the bass doesnt over power them.

Pros Great customer service and quick shipping clean sound, with crisp not overall bright highs perfect sounding.

Cons: none really they sound great

talk about bang for your buck

hesitant at first but once i put them next to my type x pros i was relieved. Not only can the keep up but they can outdo them and the price is definitely a nice perk too.

I think I'm gonna need a bigger AMP

Replaced 2 Sony Xplod with these and wow what a difference.. these Monsters hits hard.. Now I get a nice clean mid bass and the highs are very clear..

I have a Clarion EQ hooked up to my Pioneer gm6400 just for the 6x9 and I had to turn all the levels back to 0. Unfortunately my amp is only 75w rms at 2ohms x 4 (2channels bridged for a 10" sub) so I have to upgrade my Amp since I cant crank up the volume..My rear deck now rattles so it now its also a Dynamat project..

These speakers brought out things I have not experienced before with my Sonys good and bad ;)
Definitely recommend these speakers to anyone but be aware the thin metal on the rear deck will shake so please use sound deadening material.
By the way C********** stated these won't fit my 07 Altima but the DB691 would.

Maybe because these are rated at 2.7 ohms? But they fit perfectly no mods, brackets etc just can't use the Polk grills..

not bad.

These speaker's aren't to bad, I think my jl audio speakers that I had previous to these mm's sound better at extreme volume.

Great Clarity

Great speakers that allow you to crank it up inside without blasting out the neighbors. You can definitely hear me coming but you don't hear the annoying rattling that most speakers generate. These speakers are with out a doubt the best bang for the buck!

I put these in my 2006 Harley Davidson Electra Glide Classic running the stock radio w/o an amp. They are a huge improvement over stock, and have amazing clarity and bass. They do get louder with use. I had to ziptie the crossovers to the fairing supports, which was no problem. I had to remove the little speaker covers, but the speakers look cool. I've washed the bike and they've been wet several times with no issues. I may try a small amp with them for more sound and clarity at speed! Highly recommend!

good product

I recommend this product,sounds good and easy installation

great product , amazing price

I am very satisfied with the product. The sound quality compared to my old marine speakers is a huge difference. The system has sound filtration so the sound can not be more clear. overall it is a great product for marine use.

Polk Audio MM521 Speakers

I have used many brand marine stereo speakers and these are by far the best sounding speakers that I have used. Have installed about 300 stereos in golf carts and now this is the only speaker that I use.
