Hi Leuds! I have currently installed the following components: Hifonics Zx6400 4 x 85 RMS (4 ohms). There are connected: Front Focal 13er – K2 Power 130-KP Rear – hat rack Mac Audio 6×9″ – nothing great, only for rearfill”Small intermediate question: What can be put in as a reasonable replacement (6x9er)?” Sub-AMP: Rodek R2180A2 1x600rms and there is an Emphaser 12″er – XT3 battery – Northstar Have it installed about a year ago. Parallel to the amp supply is anAlfatec capacitor with 3F TROTZ ALLDEM I have a light flicker of the finest kind. That is, in the evening, when I turn up even the instrument cluster flicker along with it. This is of course animal-like on S***. My guess would now be the alternator, which I would like to upgrade (from 80A power) to 140A. In addition, I see a worsening of the problem, as soon I will exchange the sub for a GZ, which is to be fed by a GZNA2800X, which ALL already with a 200A However, I absolutely want to have the sub, since the current spare wheel dump solution (19mm MDF) in the installation does not quite push what I wish for. (E36-320i-Limo with foldable rear seat, which of course should remain APPLICABLE ) My guess now is that the complete power supply will collapse when I will exhaust the installed components. What do you think, where is the weak point with me? I don’t like to put it in (lack of space). For that I used the Northstar. Is it the pastry? Do you want to add more? I connected it parallel to the supply of the BEIDEN amps. Should it be connected alone for the sub-amp? Thank you in advance for all your information & tips! Noby – as an addition: cable set is still 16mm2 (with the BMWs 6zyl. eh No matter, since battery in the trunk, i.e. cable path max. 2m for back and forth) But when the new amp is installed anyway on 25mm2 “hoc” Classified’
