I have been using Helix speakers for my previous 2 cars and they were great. I bought a new car and wanted to change my stock speakers so I went to my usual workshop. They told me they got a new brand and model and I tested it and compared and found that it did sound better. I bite the bullet and changed it and have not looked back.

I was deliberating for a long while on which component speakers of the same price range , hertz, German maestro, rainbow, audio system, helix, ground zero. Finally I selected esatto comando co-s62, which is not as advertised. It's made in Italy. The warm and clear notes swayed me over. Kudos to auto image. They are trustworthy in their recommendation, and help me adhere to my budget. The bass is good enough, so they even said don't need install subwoofer. I am enjoying my ride even more now. In fact I actually stayed on more one more song after I had parked the car :)
