running a 1k watt kicker in a 09 volvo

What spec coax are most of you running that has these big power amps?
Just curious, as the ones I have seen that come through our shop for maintenance work with electrical issues are running the mini-8 or rg-58. Have replaced 3 ecms, 2 on a Cat and one on a Cummins that failed shortly after some golden screwdriver installed these boxes.
Stray RF in modern electrical systems is a real deal, especially Cascadia's and Volvo's.

I have a taken field strength readings on some of these so-called supertuned setups and have found only about 10% of the power is getting to the antenna, the other 90% is going elsewhere, including the drivers body.

As others have stated, heavy gauge (10 or larger) straight to the battery, both positive and negative (plus a added heavy gauge wire to the frame), high quality coax (not the pretty clear stuff), and a quality antenna (not the pretty ones with big cans), and you may be safe running 1k without frying your trucks computers or yourself. If you plan on running dual antenna's (not recommended in a modern big truck), they need to be spaced 9 feet apart to even think about adding anything!

Just for grins, google RF Burns, and educate yourself on what running high power and sitting in close proximity to it will do to your body.

Good Luck

 

Use high quality coax, run hot wire to the battery case and connect to the terminal where all the batteries hot cables come to and ground to the fram. I use 6 gauge wire for my Dave Made 5 pill. I have no issues.
