I've been researching 4-channel amps to power my speaker pods and a small sub. Kenwood is not really a brand I gravitate toward but this amp has caught my eye for several reasons and gets rave reviews. https://www.crutchfield.com/p_113KACM3K4/Ke...4.html?tp=35782

An unexpected bonus is that it uses only a 10 gauge power wire and draws just 22 amps. That's within limits the stock harness and fuse block can handle, particularly given that I'll be running all LED lights which will cut down on current draw. Eliminating the hassle of fishing a fat wire through the harness snorkel to connect directly to the battery is appealing. What do you electrically savy folks think?

22A is over 300W. The voltage in the cabin dims when two 55W headlights are turned on. I would recommend running a separate wire from the battery to the amp. May even want to add one of those 1 farad capacitors at the amp as well.

Funny that you mention dimming lights, a long time ago my younger self put a big amp in my Super Beetle (12V) and when driving at night with the headlights on, whenever the amp kicked in the lights would completely go out for a second and then come back on dimmer than before.
