How to run rca's to 4 channel bridged . I ran one set off front left and one set off front right with splitters. Landed left rca's to 1 and 2 and right rca to 3 and 4 believe that is correct . Now my amp Memphis sixfive 400.4 has a 2ch / 4ch. I'm I still in your channel since I used all four inputs or 2 channel since bridged . Oh and hu pioneer 4400 has a output switch that says that or subwoofer .technically not useing rears and subs are on there own rca's. But I have to choose one .
No, sub is off monoblock. I have channels 1 & 2 on the front left and 3 & 4 on the right. Hu I ran one set then y splitter to amp input left to front right to rear. I think I got all that right but I have 2 channel / 4 channel switch on amp I went 4 to 2 so should it be two but used all four inputs on amp so should it be 4. Also in setting there is an option rear or sub technically I'm only using the fronts off hi and subs are on there own rca 's but I have to choice one. No rear speakers and sub on its own amp . The 2/4 channel switch on amp and rear/ sub on hu. Thing is I get the left side on but not right if I switch rca's the left is weaker. If I switch both of them right is ok and left is weak . I think either the rca is bad or from head unit the out put rca is bad . .
From crossovers I went positive to 1 neg. To 2 and other crossover same but 3 and four . But read somewhere I don't need y splitters because I have the 2 channel 4 channel switch on amp
Some amplifiers bridge the front channels. Others bridge left or right. What's important is that the speaker is connected across the same two inputs. With correct bridging, you input to one channel with the speaker bridged across two channels and then insert the second signal and see the output voltage driving the bridged speaker double. If the 2/4 switch gives the two bridged channels signal, it doesn't matter if you use the switch or y-cables. If the 2 input switch doesn't drive one normal and one inverted channel (bridged pair), you will have to use the y-cables, and feed the two channels that you need to use to have two bridged pairs.
