Coming from a panel van with 2 rubbish OEM speakers in the doors anything is an improvement!
I upgraded the door speakers to a JBL component set with tweeters atop the dash, 2x JBL component sets in the rear cabinetry (which provides a decent bass output on its own)...still felt something was lacking up front.
The sub provided just that nice extra thud for the front row listeners
