question about running more than 1 sub

[Ununpentium 10+ year member]

if im running 2 subs that are each 500W RMS with the amp bridged putting out 1600 watts, is the amp running a 500W load or a 1000W load?

please reply back if you need to know the details on the subs (# of voice coils) (how they are wired)

Load is measured in ohms. Power is measured in watts. Power is dictated by load.

With only the information given, we can't tell you anything other than you are a noob.

I didn't mean it in a bad way, but maybe I should have.

If the amp is putting out 1600watts, that is what the subs are seeing.

maybe i should rephrase the qestion......

if i wire a 4ohm DVC 500W sub in series, does the RMS wattage of the sub decrease to 250W as the resistance increases to 8ohm?

No, the rms rating of the sub is the rating it is. What kind of subs?

Kicker CompVX CVX124 what i metioned throughout this tread was an example

# Recommended RMS Power: 750W

# Peak Power Handling: 1500W

The RMS power is just that, no matter how you wire it. If you had 2 of them you would need at least 1500watts.

As already stated the RMS wattage of the sub is whatever the RMS wattage of the sub is ~ which is solely dictated by the build of the particular sub in question.

If you wire a DVC 4 Ohm driver with the coils in series then yes, you have created an 8 Ohm nominal load to be presented to whatever amp is going to drive it. No, the RMS wattage capability of the sub has not changed - it will still be 500 watts but if you show an amp this 8 Ohm load you have created then it will need to output 1000w at 4 Ohms to feed your sub 500w at 8 Ohms. You aren't changing the physical makeup of the sub by wiring the coils in series....you've only increased the amount of resistance presented to the amplifier hence the necessity for it to make bigger power at 4 Ohms to give the sub the wanted power at 8 Ohms.

ok cool, cause i read somwhere online that when you wire a sub in series, it doubles the resistance and halves the rms wattage at the same time.......dont think the guy who posted that knew what he was talking about

anyways... im running a PPI PCX 2400 bridged for the nice 4ohm 1600W channel, so do you think that the subs i listed above will match nicely or should i use a lower wattage sub, say...... within the 500 - 600W rms range??

Nope - wire the coils on your two subs like so:

to show that bridged amplifier a 4 Ohm load and then set the gains on your amp according to the method clearly outlined in the gain setting tutorial here and wang away!

Da*n, I didnt feel like doing all that, but you are right.^^^^^

I dunno about that professional bit but you're more than welcome for the help //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
