Does anyone know what are decent 6x8 speakers for my 2005 supercrew? I don't want to spend a ton of money but I want it to sound decent. Anyone got any ideas?

 

Well there are in fact many

I have just ordered a pair of Polk Audio DB571 5-by-7-Inch Coaxial Speakers.
I will stick them in the front doors just to see how much better they are over the stock speakers.
Then the Idea is to get a New Head Unit Pioneer 3200BT and get either
Kenwood Excelon KFC-X683C 6"x8" 2-way Car Speakers cheap on Amazon
Or
Focal Access 570 CA1 5 X 7-Inch Coaxial Speaker Kit Have only found them on Amazon.
Then move the Polk to the rear and the new ones to the front.

There are many more of cause.
I'm sure more will chime in.

Once I get the installed I will give some feed back

 

i got a pioneer avic d3 and my factory speakers are the 25watt ones they are great low volume levels then start distorting...im wanting something that puts out decent midbass

 

Rockford t1 6x8 door speakers. look on ebay. A pair costs $78. very nice sound quality

 

Got the Polks installed today and the sound is definitely better no doubt, bass is better than stock as well.
Only issue the mounting holes did not match up I had to enlarge 3 of them for some odd reason.

 

look into a good set of component speakers...much cleaner sound and more options for upgrading your system in the future. if not look into mtx speakers. i had some in my truck before i upgraded to components and they pounded

 

Just ordered at pair of Infinity 6830cs 6 x 8/5 x 7-Inch, 270-Watt
Infinity 6830cs
I will give you a heads up when installed
