Problems about TDA7498 amp

I've been playing with TDA7498 amp for a few days and indeed it has some roller coaster of a crossover band. It's relatively flat from 200 Hz to around 23 kHz, there's a huge spike around 26 kHz, then drops off to zero gain at about 28 kHz. On the low end, gain drops slowly from about 200 Hz until it goes down to 100 Hz then falls like a brick. Perhaps this amp was made for dogs?
