hifonics tx4405 titan amp

 I was wanting to know how to bridge this 4 channel amp into two? It is an older model, but does have a 2ch/4ch mode switch and would be rated 220w@4ohm. And on the line input which ones do I plug into 1 & 2 ch or 3 & 4 ch as that is how the X-overs line up.  "conspiracy in silence speaks louder than words" -John Lennon

You will need to put the 2/4 channel switch in the 2 channel position.    Put signal into input 1 and connect a speaker to channel 1 and see if it plays.  If it does play remove it (the speaker) from 1 and connect it to channel 2.   If it plays on both channels 1 is the correct input.  If not try input 2 and repeat the process.    Once you find the input that feeds 1 and 2 you will need to find the one that feeds 3 and 4.  This may be input number 2 or 3.   If you can not get all 4 channels to play individually with only 2 inputs fed you may have to get some Y adaptors.   Let me know what you figure out.

I'm a little confused, I only have a couple(2) 10"s I'm also using a Scosche FAI-3A  signal converter. I found the pos and neg to the back speakers wired them into the signal converter using only two of the four RCA out puts, plugged them into the 1/2 input on the amp, had the amp in 2 ch mode, speakers wired from 1/2 ch on the amp and for some reason the speakers are only getting a signal from one side???? The last time I used this little guy(the interface adapter) I had it hooked up to 2 amps and one was the Hifonics amp  using all four channels..Should I just use my Y type RCA's and hook it up to run all four channels,then switch it into 2CH mode and only use 2ch speaker output from the amp?? Is this safe for the amp?? I'm just trying to squeeze as must watts as possible from this amp??  Oh and the 10"s are 4 ohm SVC "conspiracy in silence speaks louder than words" -John Lennon
