Just installed these today in my 1990 4runner in the front doors and bought speaker spacers wich were not required. Hooked them up to a orion cobalt 600.4 amp wow these things bump!! Ive read some reviews saying they have no bass thats crazy! These little things got a lot of bass plus highs and mids! Maybe the past reviewers were not putting enogh power to them. I also have a new pair of boston acoustic 6/9 these things blow them out of the water in every way! So time to get rid of those and get another pair of these! Get these you will be happy!! Cant wait to hear how they sound in a month after a full break in period!!
Update Sep 29 09 Just had another pair installed in the back and all I have to say is WOW!! Like I said before I had Boston Acoustic 6/9 s95 in boxes and they just cannot hang with these! You can get away without a sub with these! Love em!

I purchased a set of four DB651’s to replace the factory speakers in my 2004 Nissan Sentra. My intention was to replace the entire factory sound system piece by piece, but once I installed these speakers I realized I didn’t need to change out my head unit or add an amp. These speakers sound perfect with the factory HU. I can turn the HU up to maximum volume and the Polk can handle it with no distortion. When I first installed them, I had a raspy popping sound, but I realized the factory subwoofer was still connected. Since disconnecting the Sub the sound has been perfect! These speakers pick up the bass perfectly, so I decided not to add a sub at all. The sound isn’t competition quality, but more than what I’ll ever need. Perfect full-range speakers for the average listener. Purchasing these speakers saved me a lot of money on replacing the rest of my system. Thanks Polk!! You have a new fan!

I bought these to replace speakers in a Pontiac vibe. I am extremely please with my choice. I also replaced the factory radio because the CD was skipping and hooked these speakers up to a JVC replacement radio. Wow, what a difference. I read several reviews b4 I bought these and would agree with many people that these speakers sparkle with brilliant sound. The replacement was easier than I thought. It was an excellent choice and I would recommend it to anyone.

Got these and the 4″ to replace the odyssey’s speakers. the fronts already had infinity reference and these polks were a little better in the mids. the 4″ were a huge improvement over the factory paper distortion machines.
after changing, there was really no bass to speak of in the minivan. we added a Basslink sub and wow, very nice combination. excellent musical sound, good with reggae and techno etc. fat strings sound great with this combination…but do not expect the Polks to deliver any of that thick sound in a odyssey, maybe if you have a few pairs they might have some punch.
very nice mids and highs and i’m happy.

I love these speakers. I just replaced the front door speakers in my 2009 GMC Sierra with these.
These are great replacements for your stock speakers. I am running them off of the stock stereo and they sound perfect. Very loud and clear. Tight bass, and crisp highs. I can turn the volume to max and there is zero distortion. These are an awesome product.
The Crutchfield advisor said that didnt fit but I am a DIYer and figured I could make them work. The only reason they didnt fit is because the stock speakers were built into the door mount. I cut the stock speakers our of the mounts. Did some trimming to the mount and then the Polk’s fit perfectly.
The stock mount was a formed plastic piece that the speakers were built in to. The mount snapped into the metal of the door and were held by a screw.
Awesome product.
