Summary: This pair of DB6501 replaced the rear stock speakers for my 2011 xB. With Kickers SS654 at front as the mid bass driver, overall performance is great. Component speakers with the crossovers can definitely improve sound in details. These speakers have adequate bass. For extreme bass lover, you need a subwoofer instead. Also, an amplifier is highly recommended to drive these high power speakers. You won't get wrong with DB6501!
Great quality, great sound, just a great product!!!

Summary: Bought these speakers for an entire upgrade to my 05 Chevy extended cab Z71. Pushing them w/ 2 channels from a Kenwood X700x5 and they are simply amazing. Don't let the size fool you. They rock and have way more thump than you think. Quality and sound is A+ and just what I was looking for. I'm running 45RMS to these and they eat it up and handle everything I throw at them. Mounting was a snap, Used self tapping screws, for existing speaker holes didn't line up.
Summary: Purchased these and installed in the front doors of my 2005 Chevy Silverado Extended cab. My factory speakers were horrible!! I have given these a month to break on and get a good idea of how I like them before giving my review. They are awesome super clear highs and Midrange. A little bump more than I expected. Running these with a KTP445U at 45 watts RMS. I'm sure these could handle twice the power!! Finally some good sounding music in my truck.
Pros: Easy installation Great sound Marine certified
Summary: I just blew my passenger side speaker, and I was bummed, because of the price I paid for these. Then, as I was looking up the warranty info, I remembered that I'd actually blown one of these Polks right after I bought it. I have an amp, bridged to 90w RMS per channel, with the gain set to about nill, and an Alipine HU I purchased here. After reading several reviews here about build quality on the Polks, I realize it's not me; it's them.
Summary: I found the Polk speakers to be of excellent quality. The speakers were competitively priced. I was unaware of what I was missing from the tweeters until these were installed. The bass is also a noticeable improvement. The 2-way speakers were very easy to install. The component set took a little homework for a novice(my first install). The supplied speaker mounts and wiring harnesses were priceless. However, the Crutchfield team is truly awesome with their support.
