Very urgent!!! Please answer my question!!!!

Hi! At the MediaMarkt there are currently various offers concerning autohifi. Was there earlier and had me advised. The result: 3-way system by Pyle (PD 69 S 3) for 55€ (recommended price: 178€) with 2x 180 Watt bass tube by JBL for 115€ with 400 Watt 4-channel amplifier by Pyle (QA 4400II) for 144€ (recommended price: 255€) with 1000 Watt I wanted to buy and have it installed in the morning, as the installation is for free. My question: 1000 Watts are not a lot for speakers with 360 Watt and ́ne tube with 400 watts? The seller said that this was no problem. What do you mean?? Please answer quickly, not that everything sounds crappy and the speakers burst (or similar). Should I then rather take ́n stronger subwoofers? If so, how much watts should he have then? The seller also said that in any case a bridge must be made. Thank you already in advance!!!!
