So I'm replacing some 6x9s in a 1992 Bonneville SSEi, but the previous ones had 2 sets of amplified inputs running to them each, I'm guessing there's a stock crossover somewhere (but possibly it's integrated into the stock amp).

So of course these new Pioneer 6x9s only have one input, and I'm sure their own internal crossovers...

What's the best solution to this problem?

Thanks guys.
