alright, ive done a lot of reading but I still have some questions.

lets say I have 2 dual voice coil 10" subs. these subs are wired up in parallel to show a 1 ohm load. i connect these subs to a 1 ohm stable amp (800W RMS @ 1ohm)

My question:

does each sub get 800W, or does it split between the subs (400W to each sub) or even btwn the voice coils (200W to each coil)?

its 800wrms total, 400wrms per sub and 200wrms per coil. so two of the three statements you made were true.

yes 400 rms each sub/ and 200 each coil

If we learn from each success and

each failure, then we can improve ourselves

Each sub will get 400w RMS total.

would wiring in a series change this? or do people not wire subs in a series ( i don't see why you would)

If one doesn't have a 1 ohm-stable amp, the subs would have to be wired in series. Series wiring doubles the ohm load (to 8 ohm per sub), whereas parallel wiring halves the ohm load to 2 ohms per sub. That is, of course, if each voice coil is 4 ohm rated.

yes changing your ohm load will effect how much wattage is being drawn from the amp....the lower the ohm load presented to the amp the more power the amp will produce...so 4 ohm compaired to 1 ohm 4 ohm is going to be easier for the amp to produce yet it will be less power.....if you look at your specs....you will see the difference in power between 1ohm,2 ohm, 4 ohm etc....

just make sure you dont use a 1 or 2 ohm load if your amp cant handle it... im almost 100% sure all amps can atleast take 4 ohm load
