Ladies and gentlemen,…read more stay as far away as possible from them! I was promised a flawless sound, inspite of the fact we agreed to NOT change the OEM Radio. This gentleman promised me an amazing result. I have waited one month ti be scheduled. The sound equipment installation has taken 3 days instead of one. The day I have taken my car back, I got inside, was not paying much attention. All I could realize was a loud track set by him playing, plus a background noise. He mumbled some gibberish about FSA that it sounds cool and all with his overly praised settings. I asked if there is something that coukd be done to fix that background noise. His answer? Again with fast paced foggy explanations. I got out of there not thinking for a moment that the Bass could have been completely compromised. Beforehand had he also praised the fact the car does not vibrate at all, meaning he has done a good jib at isolating the trunk. But the reality was another one. So I then put one of my tracks and realize there is no bass at all. I call him immediately - Hallo AMB... what can I do for you? - Hallo it's still me, there is a problem with the liw feequencies... - Huh? Ne! Come by, come by and we'll see... And he continued with his gibberish. After a day or so I realize that SOME bass comes once I set Fader to right or left. I immediately tell him this and he was like he knew and as a fix I quote:" ok then we would have to connect it MONO". And I was wondering in what manner did he connect the cables first off? Anyway I bring the car back and he changes the connections. The sound was not clean and the bass very limited.
