Hey there, so in the future i'm building portable speakers with a tda7294 anplifier off ebay, the problem is i'm running this from a battery so i'll need an smps power supply to give me double supply off my battery, so the smps gives out +-35v but the amplifier only takes in 24-0-24 at max, so i was thinking of making a high current voltage regulator.
Any SMPS can be modified for lower voltage cus that usually means lower power so a smaller stress on the power elements, if the SMPS is regulated then just by changing the upper resistor on the voltage divider of the feedback network will reduce the voltage at the needed level, if the SMPS is not regulated then you need to modify the power transformer, rewind the secondary coils for the needed voltage.
If you are not sure what to do then post the SMPS schematic here and i will try to guide you trugh it.
It is not comparable to present-day, state of the art converters for efficiency, but it's still OK, and much better anyway than what you intended to do.
If the SMPS has a floating output, that is, if there is no connection to ground on either of the outputs, you can use them just like batteries. The LM393 consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0 mV max for two comparators which were designed specifically to operate from a single power supply over a wide range of voltages.

The ULN2801A-ULN2805A each contain eight darlington transistors with common emitters and integral suppression diodes for inductive loads. The TIP31C is a base island technology NPN power transistor in TO-220 plastic package with better performances than the industry standard TIP31 that make this device suitable for audio, power linear and switching applications. The LM7909 three terminal negative regulator is available in TO-220 package and with a fixed -9V output voltage, it is useful in a wide range of applications. The dsPIC series of microcontrollers are very high performance and are excellent for digital signal porcessing. FreeDatasheets is a resource for engineers, students, and electronics hobbyists to locate semiconductor datasheets from a single source.
First of all because it will not cheap to build this regulator, if only for the heat sinking you will need.

Operation from split powersupplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. As an example, the ADXL325 is a small, low power, complete 3-axis accelerometer with signal conditioned voltage outputs. Second, you will waste precious battery power with this scheme, at least half of all your battery capacity, and.probably more.
It can measure the static acceleration of gravity in tilt sensing applications, as well as dynamic acceleration resulting from motion, shock, or vibration.The user selects the bandwidth of the accelerometer using the CX, CY, and CZ capacitors at the XOUT, YOUT, and ZOUT pins.
