Installing 12 v power port; Question

Give it a shot as it's hard to say for certain without knowledge of the variables involved. Inverters abhor any significant voltage drop which is why it is suggested to wire them close to the battery. The 12Vdc socket in my entertainment center made my inverter squeal loudly in non-compliance when I attempted to plug and play, no problem just ran wires direct to battery. My inverter is a bit larger than yours in order to run additional items along with our flatscreen, although we rarely exceed more than a 130 watts at any given moment.
