reedal Posted July 25, 2015 Report Share Posted July 25, 2015 It means that when you only have four channel input (two front two rear) it sums (adds) the signals to give you two more channels for a sub out as well SMD Tool Map https://www.stevemeadedesigns.com/board/topic/193176-smd-tool-map-new-november-2014/ Build log https://www.stevemeadedesigns.com/board/topic/197217-reeds-03-tahoe-hat-sqaq-singer-xs-shca-cockbox-80prs/?page=32 Link to comment Share on other sites More sharing options...
mothra Posted July 25, 2015 Report Share Posted July 25, 2015 let's say you have OEM tweeters and mid in your front door that are given signal through an OEM actively crossed amp. the signal summing device will take those 2 different signals (tweeter 4kHz-20kHz, mid 150hz-4kHz) and combine their signal to make a single signal of their combined frequencies. if nothing changes, nothing changes You don't know what you don't know, till you don't know Link to comment Share on other sites More sharing options...
bassman619 Posted July 25, 2015 Author Report Share Posted July 25, 2015 Ok..so what i should do is sum the channels to make sure i have a complete signal right? You need trunk space to get groceries and shit...bitches love groceries Link to comment Share on other sites More sharing options...
Skullz Posted July 25, 2015 Report Share Posted July 25, 2015 Summing = combining the stereo left and right channel into a single mono for sub output. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...
Skullz Posted July 25, 2015 Report Share Posted July 25, 2015 The summing of the front to rear is so you can use a single pair of rca patch cords instead of running 2 pair. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...

firebirdude Posted July 26, 2015 Report Share Posted July 26, 2015 It means that when you only have four channel input (two front two rear) it sums (adds) the signals to give you two more channels for a sub out as well Summing = combining the stereo left and right channel into a single mono for sub output. While many 5-channel amps do indeed have this feature, he's talking about a full OEM integration summing device. It essentially does the same thing. Exactly how it sounds. It takes high-level all channel inputs from any and everything the OEM system may have, sums them all up into one signal, and then outputs low-level RCA outputs. This piece of equipment is generally used when a factory amp or possibly factory head unit had odd outputs/crazy EQ curve. Link to comment Share on other sites More sharing options...
reedal Posted July 26, 2015 Report Share Posted July 26, 2015 Separate. If it has six outs and you only need four then separate will be fine for the components SMD Tool Map https://www.stevemeadedesigns.com/board/topic/193176-smd-tool-map-new-november-2014/ Build log https://www.stevemeadedesigns.com/board/topic/197217-reeds-03-tahoe-hat-sqaq-singer-xs-shca-cockbox-80prs/?page=32 Link to comment Share on other sites More sharing options...
_paralyzed_ Posted July 26, 2015 Report Share Posted July 26, 2015 People are giving you generic answers for summing, and not realizing that you need to know what summing effects with your particular piece of equipment, the 6ix. It depends on the system you are integrating it with.If your vehicle has separate amps for tweeters and mids you need to sum. Link to comment Share on other sites More sharing options...
