splitting rca's

How many times can you split an rca output before you lose signal and degrade sound quality? The reason I'm asking is, I have a single mono-sub rca output from my Blaupunkt Casablanca cd51, and I need to get the signal to two Bazooka ela100.2 amps, each driving a Bazooka 10" sub at 4 ohms. Neither of the amps have an rca output to daisy chain them. I dont want to use the front/rear rca outs from the HU because the rear outs go to an amp for my 6X9's, and I dont want to lose the effect of the fader. Can someone please help. I really like the power (330 bridged) each of these amps put out, and the price is unbeatable, ($65 each, $130 for 660 total watts of rms). Also, are there any  problems with the two amp two sub set-up such as, matching the gains or, differences in output of two individual amps of the same model?

You can use a "Y" adaptor to split your RCA signal without fear of any loss of signal. Set your amps up the same and you should be fine.sparky
