Here's a tip on installing your mobile linear. Most guys never use large enough wire for the power feed. I ran a Texas Star 250wt. bilinear for a long time. The distance from the battery to the box, due to the routing I picked, was twelve feet( In a 1990 T-Bird). The correct wire-size for this(A 25 amp draw), was #8 THHN copper wire. I gained forty watts of swing by doing this, to 290watts on a calibrated peak-reading Bird tru-line meter.
12VDC loads in a car/truck suffer a severe voltage-drop. This has to be taken into account when installing. Power for my radios is always with Mini-8x coax. Virtually no noise and enough current draw for my Grant XL. |

I run #8 from the batteries (12 ft run) to my 2x4 Xforce XT400 and at 15.1 volts the pep wattage on my Bird 43P reads 1100 and 250 swing to 400 on average. The power wire never gets warm. I think most amp ratings on these amps are way overblown. |

If you were to measure voltage where your 8ga wire meets the amplifier under load, then test again with 4ga wire feed (+/-), you may think differently! |

I'm curious to know where you are getting/reading that 15.1 volts from.
