best not to mix ohms...you need a three channel amp to power the JVC and a sub, for the sub...

Nothing will get damaged, you will not be getting a stable amount of power to each speaker/sub. Electricity automatically follows the path with lower resistance, so if you have a 4 ohm sub in the same terminal as an 8ohm speaker than the majority of the power will go to the sub, and there will be a loss of distribution, the power differential will not be even between both sets of wires.

The way to do what you describe is use a four channel amplifier - you bridge the rear two channels to run the sub, and leave the front two for the JVC speakers.

I was thinking about briding my midbass to one channel and my components to another channel of a 2 channel amp. Then I got to thinking, that can't be done if the amp doesn't have multiple crossovers can it?

It can't be done, period...your components are stereo, they need two channels. Either run them off two channels of the same amp, or you need two amps...

i am getting this amplifier http://www.justkenwood.co.uk/stock01/kac8452.asp someone recommended it 2 me i think its a gd 1 ... as you wer saying earlier the sub is 4 ohms and the speakers are 8 ohms so most of the power will go 2 the sub. is it a massive difference or small. becuase if its small that im not too worried about it
