I agree with these guys!!! Sq is basically a very clean sounding system. I thought i wanted sq and i just wanted loud and clear. Cost me over 2grand snd not happy with volume. For sq you will need to stop all vibrations in car wich is a ton of work. You will need s dsp wich is 300 or more. Placement of tweeters and mids are crucially important. You will need custom locations becuase whoever tunes the system will tune it in a way that every frequency is clean which in my case it means most frequencys are lowered alot to sound clear which made the system volume very low. You can achieve loud amd clear without all the hasle. Sq is on a very high level of clear
