These speakers are ok. They are better than stock which is all I expected. I got what I paid for. Like other comments here, they are lacking some base, but that may have to do with the power and sound tunability of the stock head unit. I planned on just keeping my stock head unit, but now I have the bug to go all the way and get a better, and hopefully more powerful head unit with more ability to fine tune the sound. I do not use an amp, subwoofer and all that. I put one of each of these in the doors of my 2010 Dodge Quad Cab 1500 with KS35s in the corners of the dash. The KS35s are a great compliment to the DS525s. I've been buying from Crutchfield since about 2001. . No one has the customer service Crutchfield has. No on provides all that you need to have the confidence and abilty to do the installation yourself. No one provides all the information you need such as product overview, details and customer reviews while shopping in one place. There's no reason to go anywhere else for your audio needs!
Pros: Great construction. Ok sound. Right price
Cons: Lacking some base, but "the jury is still out."
