you have both?
if so Build
for both ....
that said thou..........to get the L7 as loud it will take more Power
than the cvr's so if you are planning to run either setup off of same amp it will depend on what Ω load /amp rated power but as a general answer to a general question if you have the room and on what little info you have given (or not given) run the cvr's but it sounds like you need a better design and possibly a better amp
