I think not being as good as the quartz is subjective. Arc audio is well established brand but more of a nich car audio brand. They concentrate on sound quality stuff rather then the bling bling of some other companies *cough* audiobahn *cough*. If you want something is more has more highs and more in your face then maybe the quartz. I personally tend to stay away from anything with a metal dome for the car but thats just my personal opinion. You should take a listen to them and see what you think. They are going in your car.
