Hi all,

I was bored so I started looking at the Phoenix Gold website. I noticed this:

Are the XS series amplifiers stable to 2 ohms bridged?

Yes, but there are a couple of things you MUST consider when running an XS amp at 2 ohms bridged. The amplifier must have a steady supply of current from the car's electrical system so you'll want to run a minimum of 4 gauge power cable from front to rear. If the main cable run is longer than about 10 feet (most are), then you'll want to step up to 2 gauge. A capacitor is HIGHLY recommended for 2 ohm bridged operation. The capacitor should have at least 1 farad of capacitance. The only other consideration is heat. With more power comes more heat so you may have to have some form of cooling fan system to prevent thermal shut down.</TD></TR></TABLE>

I am currently running 8 gauge cable and everything's been running fine for the last 6 months. Would it be beneficial for me to upgrade to 4 or 2 gauge cable? Am I somehow losing some steady power by running 8 gauge cable? (Oh yeah, I am running @ 2ohm bridged)

Also, I didn't think a capacitor would be needed for that low amount of power. Was the above text a marketing ploy? Or does it really make sense to you?

I have no problem with upgrading my wires, it would just be a little pain, but I would do it if it would be a considerable improvement.

 

If you are running 4 ohm then you are probably fine. If not then you should upgrade. Check out this http://www.stealth316.com/2-wire-resistance.htm

The max loss you want is .5 volt.
