    Why only the 80W-120W Opus PSU have remote output to trigger the amplifier and not the 90W-150W models?

    if i am correct the opus 150 has a fuse in it already why would you need another 1 for the first setup option?

    The fuse in the first option is to protect the wire not the Opus. The wire is what will cause a fire in your car.

    I have a sub amp wired directly behind my backseat. I was planning on following option #2 by disconnecting the line currently running to the amp and hooking it up to a power distro block, but was wondering if there would be any issues with the fuse(s) that I am currently using. Right now, I believe it is a either a 60A or 100A fuse on a 2/4 guage wire. Can I continue using the same fuse, or should i simply switch out the fuse for a higher rated one?

    Also, I'm a little worried about the vibration from the sub, as it would be very close to the opus and the pc itself. Any suggestions on dampeners? Rubber grommets?

    Sorry for the n00b question

    whats that green/white 2 pin wire in the OPUS150 which s right next to the motheroard power connector. Looks like the start/shutdown pins but wanna be totally sure.

    couldnt you just take the constant power from your oem cd deck connection to run the opus? theres all the wires you need right off that harness; constant, ignition/acc, ground, and speakers.

    Is the opus power supply that similiar to an amp that it needs a direct connection to the battery? (I just ordered an Opus 120 , and was hoping it would work with no problems running off the oem cd harness)

    Here's a question for you. If I had 12ga wire running directly to the opus, or in my cas an M1-ATX, is there any need for the fuse. 12ga wire can hold up beyond the the 10amp fuse on the M1. I know most people need another fuse as they go from 10/12ga down to the stock 18ga lead that comes with the power supply. Would it still be wise to run something like a 15 amp fuse anyway or should you match the fuse on the board, i.e. 10 amps?
