Opus 90W power supply wire, 8 ga wire?

**muldrick** · 08-25-2004, 12:22 PM

Just paid for and waiting for the Opus 90W.
I am currently running an 8 gauge wire about 5 ft. to the inverter in the back. Obviously the inverter is being replaced by the Opus. Question is: can the power supply to the Opus be too thick? Everybody seems to say use 12 GA. But I have the excisting 8 GA (directly from the battery)
Would this thick wire be ok?
(and ground the Opus negative wire in the back)
The acc wire should what size? (abt 5 ft length)

Should be okay, though to be safe you might want to put a smaller fuse on it before it goes into the smaller wire. For a 90w I believe a 10amp fuse would be appropriate?

The ACC wire coming back up from the Opus to the ignition switch...should I use a 12 Gauge wire (5ft)

There won't be much power going through that, so it probably doesn't matter. I'm pretty sure the turn on signal wires in "amp install kits" are 16awg.

Use 16-18G for the turn-on wire and 10-12G for the Opus. If you've got bigger, that's OK too. Just make sure you have a fuse on each circuit sized to protect the capacity of the smallest wire in the ciruit.

Thank you

I have 8 awg amp wire (pheonix gold) wire going to the opus and all is well

One quick question. The ACC cable...can I connect the ACC cable into where the radio Turn On cable is for the amp? Will this work???

Thanks!

If you have an aftermarket radio you can hook into the amp turn on to turn on the OPUS if you want to but you'd be better off hooking to the accessory wire @ the ignition harness or behind the radio. If you have a factory radio I wouldn't recommend hooking up to amp/antenna turn on as I have seen a few outputs fried doing that.
