can I split the RCA's with some Y connectors or is that just a stupid idea.
Or should I break down and buy a deck with a couple sets of pre outs? I dont like line level inputs very much but I guess I could use them too

Also any ideas on running 4 speakers off of 1 2 channel amp (Lefts wired for 2 ohms, same as rights)?

For that amps, I'm doing the same thing, somebody on here told me to get Y-cables. Haven't used them yet though, soon hopefully.

This was the thread that I started a while ago.

Easy answer? Get a new deck.

I imagine you want to run bass of one amp, speakers off another?

A deck with multiple pre-outs is going to give you useful features like independ sub control (bass up/down), allow you to adjust fade/balance, crossover/EQ settings, etc.

Some amps do support a pass-through feature that allows you to plug one amp directly into another, but I would honestly only use this myself if I was running the same sort of speaker on the other amp (e.g. 2 subs, 1 amp per sub).

you guys are quick

Hope it helps.

Cheap solution - EQ.
Pricey Solution - New Deck.
