okay i kept searching and i found this

https://www.the12volt.com/relays/page5.asp#stbm

it is switching from stereo to mono using 2 subs. But i want mono to bridged mono using one sub. So I realized that I could just used a normal switch, instead of a relay. Then i got the pen and paper out and made a schematic then did it again on paint, here it is.

If you know nothing about switch layout, then heres how it works, first off this is a 3 posistion switch or Double throw, it can be in the middle, up, or down. When up the top 4 pins are connect, but only the 2 vertical ones in each colum, not all 4 pins are connected together. when down its vice versa. So my theory is that since when you bridge an amp you use left positive and right negative, that what I could do was just have a switch that changes the positive input from the right to left channel, this should then bridge the amp. I wish the guy that made all of the electronic schematics for the site would come and tell if Im this is the correct way to do it.

Thanks

If each center pin in your diagram is the common for each respective up and down pin of the switch, yes it will work. The main drawback I see to just using a switch is you will have to run your speaker leads from the amplifier to the switch and back to the speaker, unless of course you plan to install the switch near the amplifier or the speaker. Using relays instead of just a switch will allow you to use an output from an alarm, etc. or even a smaller switch.

I think Im just going to use a DTSP, instead of a DTDP, this will get rid of the ground side which is redundant and useless any ways. I really don't mind about running speaker wire everywhere.
