First thing I did was change my tires to Continentals then installed a JBL sub with PowerBass OE652-NS2 6.5" 2Ω Direct Fit Premium OEM Replacement Coaxial Speakers Sounds amazing. But the tires were the biggest change in driving...period. Welcome to the Z experience.
I had it installed could not be happier, can adjust a hundred ways provides the deep bass I was looking for. It was installed on my Sport. Changed the front door speakers as well HUGE difference. Happy! I used custom fit Power Bass on the door.

When I bought mine, it was on sale for $2100 less. I waited until Saturday because they had a special sale with an additional $1,000 off all their cars the was included. So I drove off with it. :)
Checked with the installer and where I purchased the speakers. I STAND CORRECTED they are in fact 2 OHMS. my bad I hope this clears things up. My apologies to all.
