I am looking for some help wiring up my Alpine MRVF340 V-12 amp. I need to know which channels to connect my front speaker RCAs to giving a bridged setup. I am clueless as to which switch setting gives the bridged output. Is it the 1+3/2+4, the 1/2 or 3/4 switch setting?
Cheers Dink. Does that mean it is not possible to have simple straight connections from my hu preouts to individual channels on my amp and I need "Y" RCAs instead? I have already wired a 4 input RCA to 4 output RCA cable to my hu front and rear (left & right) preouts and was hoping that there would be another way as I eventually wish to get another amp to power my rear speakers and simply plug in the rear RCA left and right connection.
I could do but cannot afford to buy one at the moment. Does the bridging take place using the channel selection switch or does it automatically take place when the speakers are connected to the bridged setting? If it is the latter then surely it is just a case of selecting 1/2 and having the 2 RCA connections (front right and left) going into channels 3 and 4??? I am very confused now. Your help is appreciated!
I would like to have my Alpine 7894RB with front (left and right) and rear (left and right) preouts wired so that I can either run my two front speakers – bridged – through my amp and the rears powered by the head unit, or both the front and rear speakers – NOT bridged – through my amp with the head unit internal amp switched off. I therefore need 4 RCA plugs from the 2 pair preouts i.e. 4 RCA individual cables each going to 4 individual channels on my amp.
I hope this makes things clearer and cheers for your help!
Thats correct Dink for the four speaker setup powered by my amp. Im assuming I would set the switch to 1+3/2+4?
What im confused about is the setup with just my front two speakers bridged. Im guessing I should have the front right speaker +ve and -ve connected to ch1 +ve and ch2 -ve and the front left speaker +ve and -ve connected to ch3 +ve and ch4 -ve. The front RCAs should be plugged into ch1 and ch3 with the switch set to 1/2. Is that right???
