You get what you pay for
I put these in my 2002 gmc sonoma dash, they looked to be in good quality, unfortunately didn't come with the wires that have the quick-connects on the ends so i improvised. Didn't fit perfectly but i worked with what I had. Sound better than factory thats for sure. Didn't have them hooked up to an amp but i only really need them for the Highs and Mids since I have 2 12's behind my seat and they work good for that. Bass is better than factory.
