speakers volume?

[jorensmith23 10+ year member]

I've wondered about this for awhile, I know that pretty much all cd decks are 50Wx4, including mine, and mine just happens to be 18WRMSx4. Ok, so my 6x9 are 45 watts rms and my 5 1/4's are 35 watts rms. My cd deck volume goes to about 40, but anything past about 35 makes the speakers start to crackle, does this happen because the speakers are trying to draw more watts than whats available from the cd deck? Would hooking up at 35x4 channel amp to my speakers make it so they go much louder and still stay clear sounding?

My other question is that..well first with the facts, my cd deck only has one rca ouput so I can only run one amp from it, is there like an adapter that makes the two rca ouputs I have and turns it into 4 so that I can run a second amp to my trunk to run my speakers?

Thanks in advanced if you help!

I just wanted to make sure that was in fact an RCA out... it could perhaps be an aux line in FYI.

If there really is only one RCA output, you might want to look into an electronic crossover with a couple outputs.
