Short answer: yes.
Long answer: That's my opinion. For a smaller cabin vehicle, I always recommend that people allocate their speaker budgets to the fronts and give themselves time to get used to it whilst tinkering and tuning. Proper amping and sound deadening will make a world of difference. I've read quite a few posts from people with larger vehicles like an Explorer that only have good front comps and a substage and that in itself blows sway the multi-full range speaker setups they had. If it's still lacking to you after a couple/few months, then throw a set of coaxs in the back.
