Do they affect sound quality?

I have 2 pairs (4 units) of 10” subwoofers, ADS S10. I’m going to install them to my car. However, only one pair is original, the other has been repaired (new voice coils replaced). I will use a Soundstream reference 405 to power them. This amplifier is capable of driving 1 Ohm load on subwoofer channels. However, I’m wondering if I should install all of these four subwoofers in my car, or should only use one good pair. Because I’m afraid if the repaired pair will make the sound worse or not. But, the crossover frequency for subwoofers will be (always) set below 200Hz, so I’m not sure if the repaired subwoofers will affect sound quality of the whole system. Please share your thoughts.
 
If properly repaired, then only difference is new Vs used, so repaired may need some serious break in if new spiders and/or the originals have been driven hard or if each pair has separate channel tone controls, then just EQ to 'taste' and correct as they break in.

Depends on how they've been repaired, have they been restored with original parts or have they just been fixed with parts that will fit.
If the spec's only differ by a few % should be no problem for your amp, you'll need something like DATS 3 to check

If the repair was done well, you can install all four subwoofers without significant concerns, especially with the crossover set below 200Hz. The repaired subwoofers shouldn't drastically affect the overall sound quality if they were properly fixed. However, I recommend testing them in your system first to ensure the repaired pair doesn't introduce distortion or imbalances. If you notice any issues, you may want to stick with the original pair for better consistency.
