thanks Menno
I used a SVEN2 for the signal and remote. I wish I could afford a 3sixty! The SVEN2 cost about R380 so it's affordable.

I am not too happy with the DLS 4" splits - they don't go load enough off the factory HU. I am looking at maybe getting a 3 way Focal Polyglass split. And then a decent amp to run them. I tell you, once the sound bug bites you it's game over
