Im thinkin of dropping these in the front and back of my 2010 GT, without a shaker 500, just a base 4 speaker setup.

Polk Audio db571

thoughts, suggestions, critisims? Did i get the size wrong? Says theyll fit 5x7 or 6x8's.

How hard is it to replace the stock speakers?

 

Great choice I think. The db's sound really clean. I'd get an amp on 'em for sure though...But they'll sound good stock also.

 

i got 2 subs, a box and an amp goin in, will i need another amp to run these 4 speakers?

 

With 2 subs probably best to run another 4chan amp to them. Ya don't need a crazy expensive one for 'em either.

 

Have you listened to them?
