Hey all,

Here's the deal. I currently have my KAR 400.4 powering my front comps and rear fill speakers. I like the bass of the rear speakers (b/c I don't have subs yet) but the highs kinda take away from the front stage a bit. So last night I turned on the LPF on the amp for the rear speakers. Then I had an idea. Right now, I'm sending somewhere between 50 and 70 watts to the front comps. As you can see from my sig, they are Rainbow SLC-265. The RMS rating on those bishes is 100 watts. I've heard of a lot of people powering their rear fill speakers off the HU and using the amp for just the components. So my question is should I hook the rear speakers back up to the HU and then bridge the amp to power only the SLC-265s? Would this make the comps sound better, or would it be too much power for them? The ARC site says the amp is 200 x 2 @ 4 ohms bridged. Thanks guys.

Hmm possible overpowering there. You would be cutting it close... IF you had the gain all the way up.

Or... another possibility. Keep the rears hooked up as they are... and bridge the front anyway...

try it out and let us know...ive been wondering the same thing.

Big NOTE!!! Possible loss of SQ. You are bridging across channels of course. It can be done if the speakers can handle it.

Can't I just disconnect the rear RCAs coming from the HU and then set the amp so that all of its power is going to the front speakers?

kcidmil

Ehh, but the fact that the rear speakers are still connected to the amp might draw enough power to keep the front speakers from getting overpowered.

And really, the only loss of SQ is going to be the fact the front won't have a left and right channel anymore. So there's possible distortion on a song that has 2 different freq... one on the left and the other on the right. If you listen to a lot of rap... you won't notice a thing besides more bass.

How will I not have a left and right channel anymore? I will have 2 channels coming from the amp when I bridge it from 4. One channel for the left front and one for the right front. I would completely disconnect the rear RCAs and rear speakers from the amp and I would hook it up to be bridged. It would be hooked up like this (from the user's manual):

Brain fart... you guys woke up not that long ago... It's 11:30 at night here... and almost Sunday...

Ok, let me sit back and think about this one for a second.

kcidmil

Ok... that would work.... giving you left and right channel, just using front and rear sections.

But I would try just bridging the front 1st... and see what it sounds like. That way you still have some power going to the rear. Yeah you won't notice it... but anyone sitting back there would. And to be honest, I'd hate being jipped like that.

kcidmil

You'll need y connectors in order to do what you want.

That way all channels have a signal... otherwise bridging would be pointless.

Basicly... A y connector on the right channel RCA cable, and hook them up to the front speaker inputs... and then do the same for thing for the left channel, except hook them up to the rear inputs.

I did that once. . .what you'll have to remember is that most music is recorded in stereo, and often the artist will have sounds that are intended for the front, rear, left and/or right [I can't think of a good musical example <but I experienced quite a few>, but an example would be Craig David's "Fast Cars", in which a bike goes racing by]. I found this to be a problem with electronic music, and plenty of hip-hop.

Just more information for you.

true but.... in the car the left side is one channel and the right is the other so there is no way u have a sound coming out of the rear left only... the front left is going it give the same sound out....its not a 4 channel stereo in the car... its a 2 channel with fading

Those rainbows are components, right? Can you bi-amplify them? If not, try getting an active crossover.

I have the rainbow profi vanadium 365 kicks and I've decided to ditch the original passive crossover and go with an audiocontrol 4xs 4-way active crossover.

my Arc ACS are rated 110rms(220peak) and they handle my xxk2500 fine- just set your gains at 0 and set the gains by ear very carefully.
