Service 100% , shipping 100% hands down my best experience buying audio online. Haven't had to deal with customer service at this point so can not note on that yet. I decided after three years it was time to do a upgrade in my tahoe was currently running DD 12s on a DD M2C amp basic kicker highs in the doors. After helping a buddy with his SKAR system I stall I realized SKAR was on my radar so I decided to give them a shot I gutted my rig all four doors and the DD 12s and installed two sets of SKAR Audio SPX-65S One per door powered by SKAR RP-150.4AB and I'd say they are a match made in heaven , since my amp was qualified for the power I kept the M2C and added two SKAR ZVXV2 18S Built my first ever box and after 24 hours of labor I'm am back to the basics. My opinion all the SKAR products I purchased are amazing the components will make your ears bleed in a good wat and the two ZVXV 18S are from another planet or at least you can hear me from another planet I'm one satisfied old man lol certified bass head no questions I will be back , and as happy as I am I decided to stick my DD 12s powered by the SKAR RP1500.1D in my wife's 19 cadillac cts and cheeseburger grins all day long I'm happy she's happy all in all damn good experience hope this helps . Buy SKAR!!! My box is still in its bare condition but I have a plan wanted to finish it a little differently and special to us so I will post pictures when it's finished .
