  5. Customer

    제품받고 설치전이지만 많은 후기를 신뢰로 좋은제품 착한가격으로 구매를 잘한거 같네요 스피커는 교체되어 있어 더나은 소리를 들려주겠네요

  6. J***n

  7. Y***e

    I have not tested yet. Anyway, Seller sent the product with a harness suit to my car!

  8. S***u

    Product came so quickly, with 4 days by Fedex. Customer service is number 1. Well-packed. All accessories arrived as promised. Good store that can be trusted.

  9. L***o

    It took about 5 days to get it and the product works well. However, when the application collects location information and rejects it, Bluetooth connection is not available, so it is not known why location information is needed for dsp products. This part is a little uncomfortable.

  10. Customer

    Quick delivery, Easy install, good Quality, Superb Sound.

  11. .***s

    금요일 주운 월요일 페덱스 직원과 마주침 현재 설치완료. 설치만으로 소리증폭 국내배송수준으로 빠르고 카니발에 설치했어요 설정만 할줄알면 좋을텐데 설정이 문제네요. 내장된음장 (6번)했어요. 2way 스피커 설정방법이나 소스좀주세요 ㅜ

  12. G***r

  14. 무***어

    뭐하나 하기 지릴맞다는 sm7노바입니다. 알카미스-> 한국에서 20만원극초반에 구할 수 있는 포칼스피커 앞뒤로 바꿔달고, 트렁크에 싸구려 액티브 우퍼 구겨넣고, 마지막으로 이거 달았습니다. 허허… 소리가 달라졌습니다. 배선도 오디오 후면잭 찍어보여주니깐 제 차에 맞는 케이블 알려줘서 함께 구매했고 맥아리 없고 볼륨 높이면 찌그러지던 소리에 기름칠한듯 부드럽고 풍성하게 볼륨이 쭈욱 올라갑니다. 낮은 비용으로 체감될만한 소리튜닝을 하신다면 요거 고려한번 해 보세요.

  15. F***h
