The Pioneer GM-D9500F and Soundstream STL4500 can go for around the 200 shipped from the usa (quite decent). But not sure about those brands and the way they produce amps..

The soundstream amp provides:
- 4 ohms: 80 watts x 4 channel

In this situation, it would be "ideal" to bridge the channels together otherwise the other 2 channels will be made redundant. However, bridging the two channels together is quite strong 90Watts over what my speakers can handle.

I read somewhere that is is not recommended to get an amp that produces more watts than max powering watts on the speaker because IF something goes wrong, it can damage everything. What are your thoughts on it?
