richie remember i ast you about running 2 subs off 1 mono amp....

iv'e looked around the net and ppl say that its not the best way to do it...

"On each sub, youll want to send a pos from your amp to a pos on one voice coil. then a neg to the neg on the second voice coil. then with the remaining - and + youll connect a jumper wire on your sub, that connects the 2, just use a single speaker wire to connect them. do this for each and you have a 2 ohm load."

wha tha??

thats just saves on speaker cable. But the same resistance will be shown. In the cases of high wattage, its best to use two sets of cables.

wot u trying to do kurt? to run 2 subs off one mono amp it depends upon, the coil impedance (so u know what config to wire them in for maximum power) and RMS power rating of the sub and amp.

The RMS power rating for the subs are 400W RMS (1400W Peak).

The RMS power rating of the amp is 900W RMS when driving into a 2 ohm load or 500W RMS when driving into a 4 ohm load.

If you were to wire the dual coils in parallel (to bring the impedance of each sub down to 2ohms) and then connected them in series, that would bring the overall impedance up to 4 ohms - and which, your amplifier would only be able to supply 500W RMS to the whole system (250W RMS per sub) so it would be pretty shit as the subs would be under powered.

IMO, get 2 amps you tight sod

Then, you could chuck 900W RMS at each sub (both 4 ohm coils wired in parallel to bring overall impedance down to 2 ohms) and it would sound pukka
