Low volume from FRT door speakers

I replaced all of my speakers including the 2 dash tweeters. These were all directed replacement (meaning just disconnected the old and plugged in the new) All the speakers work great but the 2 in the front doors both have very minimal sound coming from them.
I checked the polarity and both speakers have wires going to the right +/-
Any ideas as to what's causing the decreased volume?

I don't know a great deal when it comes to car audio but, the 2 door speakers are Rockford Fosgate 6x9 3-Way coaxial. Not sure with them having built in tweeters that they aren't getting affected by the 2 mounted in the dash. (not sure how the factory wiring is with that. It may be like have 2 sets of tweeters wired to the same speaker. IDK ..... Any help and clarity to my problem will be greatly appreciated.

Check the specifications on the particular Rockford Fosgate 6x9 speakers you installed and see if their "Sensitivity" rating is at least 90 dB or better. I looked up that model on line and saw that it did have a 90 dB Sensitivity rating but I don't know if all of their speakers have that good of a Sensitivity rating.

A lower Sensitivity rating than 90 dB would cause a lower volume at the same power that would sound fine with a higher dB rating. I just want to make sure you didn't install speakers with a low Sensitivity rating like 83 or 84 dB which would cause the low volume you're asking about. Sensitivity is just how loudly the speaker plays at a given wattage rating or volume setting.

When you have a choice, buy American made.

Yea double checked specs on this pair and they are rated at 90db.
The head unit is still stock (getting replaced with dbl DIN soon) You think that with the upgraded speakers installed in rear doors then connecting the more powerful ones in the front doors, the head unit isn't supplying enough power to generate great sound from the new speakers?......

Hard to say without knowing the power your head unit puts out. Get as many RMS watts as you can afford with your new head unit, you should be fine. Most only come with 20-22 watts per channel but some put out more. Sony has a new single-DIN radio that puts outs 40 RMS watts per channel, I'd think you could find a double-DIN that could too.
