i dont under stand, my subs are rated for 750 rms so i wire them together the amp only sees one speaker?

Question

how can you feed theem more power with out blowing them. sparky you say they can take 10000 to 15000rms

Answer 1

No, I said 1000 - 1500 rms...

Two subs that are 750 watts RMS each when wired together is equal to 1500 watts RMS power handling. This is because each sub will get half of the 1500 which is 750.

When speakers are wired in parallel, the amp only "sees" one connection or one speaker (both as one), it doesn't care that there are two only as long as the impedance (ohms) doesn't fall below what it can handle.

For example, If an amp is 2 ohm stable and two subs are 4 ohms each and wired in parallel, the resulting impedances will be 2 ohms. If this amp is 1500 watts X 1 @ 2 ohms and the subs are 750 each, this works out.

A further example, I can wire as many speakers to an amp as long as the total impedance is within tolerances of the amp. Here are four subs, each is 4 ohm, the resulting load is 4 ohm...http://i81.photobucket.com/albums/j230/sparky3489/SERIES-PARALLEL.jpg this is all going to 1 channel of an amp. Each sub must be 1/4 the total output power of the amp.

Again, this amp would only see one connection.

Answer 2

Wire the two subs in parallel. This will produce a 2ohm load. The way to do this is the same as wiring a single dvc sub. Wire the (-) from one sub to the (-) of the other, and the (+) from one to the (+) of the other, and then bridge your amplifier and wire it to one of the subs.

Answer 3

this question doesnt make sense to me. what do you mean the amp only sees one speaker? you mean only one speaker is on? if thats the case, then you wired something wrong.

if you put 10,000 to 15,000 watts to a 750 watt rms sub, your going to just fry your voice coil.
