Thread: H. O. Alternator

You might be clipping your signal. Also, surface area is a big deal. If you aren't making good contact between the wire and the ground point then all that soldering won't help. Verify that the amp itself has a good grounding point too.

Sometimes, trying to draw too much through a narrow point(bad connection) can also cause a voltage drop and dimming lights. Positive wires need good connections too. It's a pain in the butt but I've seen guys hit 150 decibels on stock alternators without problems

All my wiring is from Knu based on audio buddy recommendations. While I'm not running a billion watts. I am pushing a single 5 channel amp and it'll make my ears bleed. Never dims a light, never an issue. Knu for the wiring, Boston for the rest.
