so first I tell you what I have in it. as you know I have a blackmaxx with 210wrms amplifier that plays through the ls covers of the shelf. then I have 2x helix coax in the a-board (the expensive for 60€). and now I finally did it, I have doorboards with the cheap helix 165mm compo for 70€. so far so good finally I have a strong and loud fs and I can put the sub on 50hz *joy. so now I have everything in front of the radio (blue point 4x25wrms), d he 100mm a little quieter since the fast start clipping, the new fs can be turned up completely without any distortion or clipping. now I would like to install something for the rear, so that they also come into some listening pleasure. unfortunately I have no channels anymore on the radio and a suitable level for the fs and the sub find ned (the sub needs 500wrms and the ls 50wrms). my amplifier compartment is also only 30x30cm large. now I thought I could install this mini amplifier with 2 x15wrms, that would have to be enough for a few coaxe in the doors. but I was afraid for the sound. does anyone have any idea??? on my page under screw corner is the expansion, yes the with the leather looks shei*e will soon set pictures with the alu border.
