SH*T! bridged 4 chan, split RCA w/ Yadaptor. no stereo sound? Balance L/R does nothin

[frankiebones 10+ year member]

i split the RCAs coming from the front output as such, i took the left RCA cable, and using a Y adaptor, split the signal to the Amp 1 Left Input and the Amp 2 Left Input.

I split the Right RCA Cable (red one) using a Y adaptor and fed that signal to the Amp 1 Right Input and the Amp 2 Right Input.

I tried using the the HU controls to balance the signal all the way to the L so i could hear if it was rattling.

I know one thing is certain, and thats that the sound is definitely louder when the balance is in the middle. however, when u put the balance all the way to either the Right or the Left side of the car, both the front left and front right speakers seem to lose volume/power equally. is it a matter of me just switching the RCAs? i thought i had it right!

From the standpt of a non-professional, it looks almost commonsensical to wire it the way i did, but i am gonna guess i will soon find out i am wrong

you still have stereo unless you're

a) using the same channel (left or right) rca for both side (left AND right)

b) bridged both speakers together on one channel

on both sides, i bridged the L+ and the R- like it said. when i used y-splitters, i took the L signal, split it and put it to the 2 left signals. one right signal got split into the two right inputs. stereo?

Re: bridged my amp finally, morels finally sound like morels

that will be stereo..

i know im being impatient as sh*t but i cant believe i f*cked something so simple up so bad...just when i think im getting the hang of this sh*t i realize ive been driving around without stereo sound and probably extra distortion for the past few weeks with no idea.

 

[frankiebones 10+ year member]

c'mon guys, 33 people have viewed this thread. at this pt, a simple, 'yeah u f*cked up' or a 'that cant be right' will do.

i am assuming (and i dont think its much of a stretch) that my equipment can be damaged from having it incorrectly connected. i mean, the amp is bridged so your already looking at some extra distortion despite the fact that its inaudible. i can imagine this would increase the risk of such distortion and could drive the amp into clipping.

also, if it looks to u guys with more first-hand experience that maybe the wires are crossed somewhere (the speaker wire that is), i gotta seriously consider that despite the fact that all the wire thats exposed looks well insulated.

i have been checking this thread repeatedly throughout the night, wondering how I could be f*cking my equipment up. i admit that i have used the forums to ask some pretty dumb questions about some subjects that were interesting, but not useful to me.

i start a thread bc i was wondering why a nakamichi HU that retails for $1300 and has unbelievable SQ looks more like an 8 track player than a CD player. that gets 20 replies inside the first hour.

help me out guys, bc i am a little baffled and worried i could have shorted something.

yeah thats me bro, http://www.myspace.com/franky4c.

tits? if u had the same discipline and 4-5 years of training behind you, maybe one day u could build some.

regardless of the size of my pectorals, u have any idea why i dont have stereo sound based on how i split the RCAs?

that kicker 650 should have a button that lets you only use one set of inputs, getting rid of all this fuss.

at least the zx does

other than that, the rca's look good.

could be an issue with speakers being cross wired for whatever reason

in light of ur response (appreciate it bro), i reviewed the owners manual again.

you were 100% correct, just gotta figure out which inputs to use. when i brought the question of whether i need to run RCAs from the Rear HU output to fill up the amp inputs, i wish u had been around then, lol.

whatever, at least i have a gameplan now, i didnt wanna risk shorting anything out by just trying an array of multiple diff possibilites.

check this out from the manual, bc i still cant tell which inputs its telling me to use when using just one. i gotta actually see the amp, and its 3:20 in the morning, and i park my car in an outdoor parking lot.

also, listed in the features is this:

"SAMS (Stereo And Mono Simultaneously) Amplifier will

operate into a bridged mono load and a stereo load at the same

time."

i know that in every sound system with stereo sound, both the L and R signals contain some level of mono signals in that that part of the signal is identical on both sides.

however, what does it mean to operate into a bridged mono load AND stereo load "at the same time."

thats what worries me, bc it doesnt make sense. what also worries me is the fact that 2 other sets of ears heard the same results when the levels were cut on the left and then the right: both sides saw reduced output in the same fashion.

really appreciate it bro.

reviewing the manual even FURTHER, i apologize for wasting everyone's time if u read this thread. it appears that when bridged, the amp is not capable of producing stereo sound. this is in contrast to the 2006 ZX (i have the KX). here are the power specs, if i'm not mistaken, and i really hope im not this time, its to be expected that they are mono.

RMS Power in Watts, All Channels Driven

14.4V,

@4Ω Stereo, 4 x 120

@ 2Ω Stereo, 4 x 170

@ 4Ω Mono 2 x 325

12.5V,

@4Ω Stereo, 4 x 70

@ 2Ω Stereo, 4 x 135

@ 4Ω Mono 2 x 250

No amp, when operating in bridged mode, is capable of producing stereo output. This is why that particular mode is commonly dubbed "mono bridged."

You're combining the outputs of two separate channels into one single output. By definition, with 'stereo' meaning separate left and right audio signals, it simply isn't possible to get it out of one lone channel's output.

 

[vaiboy 10+ year member]

When you bridge 2 channels you have 2 inputs but only one output. With the RCAs setup the way you have them now the amp is combining the left and right signal for the output. Using your diagram and assuming channels 1&2 are the left speaker, run both of the left RCAs to the inputs on channels 1&2. Then run both of the right RCAs to the inputs on channels 3&4.

run both of the left RCAs to the inputs on channels 1&2. Then run both of the right RCAs to the inputs on channels 3&4.

gotta check them wires. ......all of them.
