It is switching at under 100hz which is very inefficient.

Good SMPS for car audio is usually greater than 75khz - the required transformer is smaller and efficiency increases with frequency.

Also MOSFET's are generally used because of high-speed switching ability in faster designs, and also the low RDS on of a well selected unit provides even more efficient operation.
