2003 honda civic my 4 speakers suddenly stopped working?

I have a 2003 honda civic and i only had 2 stock front speakers they are working fine i had no problems with them at all, i also have a subwoffer connected with a built-in amplifier. Yestrday i got 2 speakers for thr trunk 6*9 edge they are 300wats peak power is 100w anyways i connected them up. And i i tested it everything worked out fine for a day. Today i was driving and my cd player was on! All the 4 speakers stopped working i don't know why, my subwoffer still works fine and i do get bass, also my radio works perfect all the buttons on it work i just don't know why my speakers worked all of sudden, i checked the connection everything is fine.
The wires i used to connect each speaker is diffrent could that be the problem thanks.

I'd just rewire everything over to double check the connections. And as long as it's legitimate speaker wire doesn't matter if it's from a home theater or actual car speaker wire should work fine, although I wouldn't advise using thin home theater wire. Might be a loose connection on the back of your deck or maybe your front and rear wires are touching causing it to cut out when turned up to a certain limit.
