Hi! Currently I’m driving a Boston GT 28 in my Audi A4 on a JL Audio 13W6V2D4 and an Audison Audison LRX 4.300, which I operate in a flash at the FS. The output power of the amplifiers is about 1.6 KW. Despite half-way proper cabling (more like a 35er did not fit under the carpet) I have a very strong flickering of the main headlights, if I turn up something further. In addition to the standard batterie is still a 1F capacitor. is now to install a small roller batterie in the back of the trunk as a supplement. These things hardly cost anything, and need very little space.Do you think that will bring what?!?!? …or can I save the action right away?
