I am currently running a Rockford 400s (400RMSx1)
and an MTX 150.2 (100RMSx2) off of 8 guage power cables w/ 1 farad cap.
I've been told I should switch to 4 gauge.
I also may be changing the MTX amp to a Rockford 550x (70RMSx4)
Should I do this?
Do I need to do this?
Why?
Thanks for any info.

Here's a little analogy I use. In Medicine Hat it gets to 40-45 degrees in the summer. we have a rather large building. If I ask you to run around the building as fast as you can on said hot day, when you get back to me you will be sweating and breathing hard. Now imagine I duct tape your nose shut and a straw in your mouth, your gonna pass out halfway around the building. That straw is too small of a power wire.

does your amplifier go into protect, after running it hard??too small of wire can eventually lead to amplifier failure, as will insufficient battery capacity.it makes the amps heat up,and components degrade from that heat.
using larger size,such as 1/0, will allow extra room for amplifier upgrades [img]graemlins/thumb.gif[/img]

actually yah, my amp has shut down after a couple hours of high volume. i got a 1 farad cap after my lights would dim a bit, thought using it in my truck would mean that my alt would be powerful enough, guess not 
so, i guess when i get my 4ch amp installed, i'll just have them change out the 8 guage for 4 guage.
thanks for all your info guys. [img]graemlins/headbang.gif[/img]
