accessory wiring advice

Post by Alex » Mon Jul 25, 2011 1:38 pm

hey guys,

basically i want to run ONE nice thick cable thru my outback to power all my accessories.

what i have down in the past (purely for stereo power) was run a 4gauge cable to a distribution block, then split that to power two amps. These are two very large amps equating to over 1600watts rms and ive had no issues with powering them.

my plan for the new car is similar, i wont be running such large amps. I was going to run 4guage down to a distribution block, then splitting that into two 8guage cables to run maybe two small amps under the front seats, then i was going to continue the 4gauge from the distrubution block into the boot area to hardwire my engel and run other accessories in the boot, like a small inverter or something.

are there any big issues in doing this? I understand stereo amplifiers use a varying amount of power depending on how hard youre pushing it/bass beats etc.

will this varying power influence the current my engel recieves for example in the boot? am i better running a seperate cable to run stuff in the boot?

curious as to what you guys can recommend.

thanks

I know I don't have to tell you about fuses and earths so that's a big plus.

I would run seperate cables for the amps and fridges etc you wish to run, not sure if you are big on using capacitors but I've heard they make a difference to having a regulated power supply (never used them so NRI)

most times I see capacitors as wank factor on giant subs that pop windows and make panels vibrate. :)

Caps dont work well at all.

Alex theres no problem with what you want to do. But one thing to think about is if you cut that 4g half way along and chuck a distribution block there you no longer have insulation in that area under the seats.

This means that place under the seat is another thing to worry about so you have to make sure no nails or screwdrivers get in that area.

Probly better to run the 4g to the back split it all there then run cables back to the amps.

The cost of the aditional cable is cheaper than a burnt out car.

Especially a family car with your kids and mrs in.
