Bluetooth speaker

I am making this Bluetooth speaker/radio. It uses a TA2024 amp an 2 ND91-4 fullrange speakers. Its a ported enclosure where each speaker has a separate volume of roughly 3.6 liters. the port is 10 cm long and has a diameter of 25mm. This will tune the box to about 55hrz according to the audiowizzards i have consulted. I have bought a cheap Bluetooth module which has a FM receiver AUX input an SD card and USB slot.
