I am on the verge of getting a set of Focal Polykevlar K2P's.

http://www.focal-jmlab.fr/gb/car/k2power/165k2p.htm



2-way system.
Woofer: 165mm (6-1/2").
Voice Coil: 40mm (1-9/16").
Magnet: 100mm (4").
Tweeter: 45mm (1-3/4") Tioxid 5 inverted dome.
Separate crossover 18dB/octave (3.8kHz).
Adjustable tweeter and midrange level.
Basket reinforcement.
Max. power handling: 200W.
Nom. power handling .: 100W.
Sensitivity (2,8V/1m): 92,5dB.
Frequency response: 70Hz-22KHz.
Grilles supplied.

Will i be ok to bridge my 4 channel amp to power them bridged, or am i best to leave 2 channels unused?
Sextons say its ok, but i thought u lost quality with bridging?
The speakers are rated at 100wRMS and the amp usually delivers 80w RMS x 4, but gives 200w RMS x 2 bridged, will this be ok?

I've never heard of there being problems with bridging and loss of quality?

Either way, I'd say go for it, just watch the gains!
