I currently have one 4 channel 2800 watt amplifier. on the back where you plug the RC As in there is two pairs of RCA sockets, channel 1/2 & 3/4 and one RCA socket line out.
Now because I have only one set of RCAs coming from my head unit, I was told that if I was to plug that lead from the head unit in to channel 3/4 to run the SUB and then plug a short set of RCAs into the line out socket and then link them into channel 1/2. this will put a signal into channel 1/2.to run my 6x9's
Question I'm asking is. Will it work without doing that because I would like to link one more Amplifier in to run my 6x9's. But I can't if I use the line out socket to power up the signal channel 1/2 on my first Amp.
I am open for any suggestions if anyone can help me with this.
use a "Y" spliter and feed both sets of in's with the full signal. Then use the amps filters to run the speakers at full off 1 and 2, then set the hpf set to ~80 and below for the sub.
Now it sounds like you are planning on running a single sub off the channels 3 & 4 bridged as a mono sub output. Be aware that the ohm load should not be lower then 4 ohms for most amps. Judging by the discription, A 4 channel, 2800 watts, I would asume that will not bridge below 4 ohms.
Next time please list the model of the amp and subs you are planning on running, it makes it easier to steer you in the right direction.
