    Question Power limits of a 4-guage wire?

    Hello all!

    I have a 4 guage wire running from my car battery terminal to my trunk that currently powers my 200watt amp.

    My question is: Can I use the same 4 guage wire to also power an opus 150? or maybe even a second 100w amp?

    I brought this question to my local car stereo dealer and he said "yes it will work". I have my doubts though. I thought I would run it by you guys also, the second opinion never hurts.

    I would like to wire my carputer and amps all to the trunk if possible. I will run a second power wire to the trunk if necessary. Let me know what you think!

    You could run your opus and a second amp no problem.

    If the current draw is below 150A, I think you would be ok.
