I have long been using this site as a reference, and find myself now needing a little more assistance. I really want to do this right so I am turning to you all for help.
I have a truck that is being used more and more for responses as an emergency vehicle (privately owned) and need to upgrade the Mickey Mouse wiring job that has sufficed for the last few years – but was only supposed to be temporary. While wiring this all up, I would also like to consider future additions such as the desire for slightly more bass to my music and a potential inverter. I have never wired a sub nor an inverter, so I’m feeling a little edgy.
What I would like to do is run one fused primary lead from the battery for all potential uses and split within the cabin by use of a distribution block. I’m not certain what size power lead to run in. Also, can grounding be effectively achieved within the cabin, or is a run back to the neg terminal necessary?
I am trying to put together a shopping list of wire and accessories needed for this task.
The equipment that will be installed is as such:
Siren/Controller – The instructions call for a 50a 4awg input and a ground to battery of 12-20awg. It drives a 100w speaker and up to (9) 15a lighting circuits. As most of the lighting is LED, the chances of actually pulling 135 amps + the speaker is highly unlikely. Actual draw is anticipated to be 28.8a + the speaker (so 36.6a?).
Mobile Radios – There will be two, but I only have the specs on one. I am going to assume the second will be comparable. Current drain (approx.) :Tx 50W/45W 14.0A; Rx Max. audio 1.2A; Stand-by 300mA
The amp that I picked out has the following specs:
• Mono subwoofer amplifier with 1200-watt max power capability
• Delivers continuous 300 watts x 1 at 4 ohms, 600 watts x 1 at 2 ohms
• Variable low-pass filter crossover (40~240Hz, at -12 dB per octave)
• Speaker-level inputs for connecting to most source units
• 50Hz bass boost with remote level control (0~12dB)
And here are the speaker specs:
• 10-inch Shallow Series subwoofer with 1200 Watts maximum (300 nominal) power handling
• Basalt/carbon fiber reinforced IMPP cone with fiber-woven radial surround
• 4-ohm single voice coil design
• 20 Hz to 290 Hz frequency response with 90 dB sensitivity
With regards to the inverter, I would like to put something in for convenience. I am not looking to spin a saw off of it. I was thinking something along the lines of a 400w unit.
Any helpful suggestions, recommendations for sourcing supplies, or quick wiring diagrams would be appreciated.
