[millertime49 10+ year member]

i have a candence txa 3004.. and i am wanting to bridge it for a set of componenets. anyone know where there is any diagrams to show how to run the rca's and speaker wires... i think i mite know, but want to make sure..

i want it 4 ohm 2 x 300

•4 Ohm RMS Power: 4 x 75 Watts @ 13.8 Volts

•2 Ohm RMS Power: 4 x 150 Watts @ 13.8 Volts

•4 Ohm Bridged RMS Power: 2 x 300 Watts @ 13.8 Volts

look on your speaker terminal...it should be labeled which connectors to use bridged...useually the two outer ....then add two Y adapters to your sub RCA's one F to two M's...set your amp and crossover settings and your ready to go

Combine channels one and two. Positive from 1, neg from 2. Then same for channels 3-4. Pos from 3, neg from 4.

I wouldn't disconnect the sub RCA's to run components?????

ya i don't want to unhook my 15" Xcon... i guess what i relly want to know is..if i put a y adapter on my left front and right front.. ( i seen a diagram once but cant remember )

left rca..to front left pos and rear left pos... and right.. to front neg and rear neg.. something like that... just can't rember... something like this but i can't read it.. tryed to make it bigger but it gets blurry..

easiest thing would to get the pdf of that amp from the company.

But that diagram looks like it.

Also, Im not sure you would need to Y the rcas, as the switch for 2-4 channel may act as an internal bridge on the input.

Run F&R to your amp, then run a set of RCA's from the pass through to your monoblock.

ok.. let me get this stright... right now...i have infinity speakers in all 4 doors ran off my candence txa 3004.... and i have my sub amp running my sub... my head unit has .. front left and right ..rear left and right and sub out.... all is working right... all i want to do now is .... put a set of components in the front.. But.. i will unhook the rear set of speaker ..i want the 4 channel amp to be bridged to be a 2 channel stereo to give the front more watts...

so far edzy and Louisiana_CRXs has some of the best advice... Thanks:thumbupw:

here is a shot of one of my old txa amps

set it to 2 channel input mode. plug your front rca from the hu into channels 1 and 2. connect your speakers using the diagram on the amp (see below).

front left speaker should be connected to the outermost + and - for channels 1 and 2, right speaker the same for channels 3 and 4.

thanks..... now should i just leave all my rca's pluged like i have them now for running 4 channel ? and will this be stereo.. or mono

i don't quite understand what you are talking about. you only need 1 set of rca cables since you will only be using left and right front. plug them into the front output of the hu and into channels 1 and 2 on the amp.

if i do it like you say in this quote.... it will only be 2 x 75 won't it ? it will be just like i have it now if i unplug the rca's for the rear... right now i have all 4 channels running to all 4 doors... 4 x 75.... what i want to do is put some components in the front, do away with rear.. bridge it so i have 2X300 to the front components.....

or are you saying if i plug rca's in to channel 1 and channel 2 ... then bridge the front and bridge the rear it will give me left and right at the 300 watts ? i just don't understand how the rear bridged will put out anything with out any rca's hooked to 3 or 4... that is why the picture i posted above they used a y spliter to get a signal to 3 and 4... unless this amp is differant ....
