I just added an Audio Control EQX to my system with the high pass on the eqx running the rainbow germs up front and the low pass to the sub. I have absolutely no experience tuning and was wondering if anyone had experience on tuning rainbow germs. The factory crossovers are still on the germs, does the eqx bypass the crossovers? Also about what tuning should I aim for on my tc-3000 15", it's in a ported box tuned to 33hz.? And lastly, my eqx gives out a 2v signal, should I add a line driver, it's probably not necessary but I was just curious. I think the shop also used the LOC that was already there to run the rca's to my eqx, should they have ran the speaker level wires to the back into the eqx for better sound or does it even matter? Thanks for the help.
