Ok, I have my amp hooked up and bass is hitting very good but now my problem is it is drowning out my mids n highs, my HU only has 1 set of RCA pre outs on it. My question is is there any way I can run something or do that I can get my mids n highs back without buying a new headunit, if anyone has any suggestions or ideas please help
Many amps like the MB Quart 4 channel onyx series (which you would use to power the speakers) have a line out that you can use as input for the sub amp, also you can get an equalizer and get the output from there.
What about a 4channel line output converter they have one at sonicelectronix.com. This is the link to it. http://www.sonicelectronix.com/item_4993_Scosche-SLC-4.html
The LOC is used when you don't have RCA outputs just the high level speaker outputs, try a clarion EQS 746 to get one RCA input and multiple RCA outputs.
