amp/speaker inquiry. (alpine/focal)

 Hi guys,I have a pair of focal polyglass 165v components and an alpine mrv f340 4 channel amp. My plan is to bridge the amp to power the components. I will be using a pair of focal 5WS's in the rear. My question is, should I go ahead and purchase the alpine mrd m300 mono amp off my friend to power the small subs? Or should I use my mrv f340 instead, and find a different amp to power the components?So...to summarize,focal polyglass 165v up front.focal 5WS's in the rear.Alpine mrv f340 4 ch amp.What amp should I get to complete the system and where should I use it? Thank you.Jason

i installed those speakers 165v in a '05 chev. 2500hd they sounded great with a mrv f340 so i would use that amp on the highs i also had 2 10' kicker on m-500 so im not sure bout the 300 but i think if the price is right you should
