A:Answer They have certifications but my advice is to steer far away from them and pay the extra money for another shop. All they do is try to take shortcuts and I had to fix their work because they wanted shortcuts and messed up the wiring (Literally did the #1 do not do with wiring- Wired RCA zip tied to Power wire which caused noise interference, their grounds were not professionally installed, they nicked a ground wire in a different car I had work done, they just want to get your money and get it done with the most amount of shortcuts possible.
