Just gonna give a quick background:

My wife and I have two similar cars with nearly identical aftermarket stereo's installed. The set-up in each car is as follows:

Head Unit: Stock Mazda unit with 6 disc in-dash CD changer
LOC: Navone Engineering 4 channel model #774V
Front speakers: JL Audio 6.5" VR series components
Rear speakers: JL Audio 6" VR series coax's
Subwoofer: JL Audio 10W3v2 (wired for 4 ohm load)

The only thing different between the two cars is the amp. I have a JL Audio 500/5 in my car which I am happy with. It delivers 100Wrms to each of the fronts, 25Wrms for rear fill, and 250Wrms to the sub.

In my wife's car we have the JL Audio e6450 six channel, which is currently wired to deliver 45Wrms to each of the four speakers and channels 5&6 are bridged giving the sub 150Wrms. As you can imagine 45Wrms is not really great for the front stage, so I was thinking of doing the following but wasn't sure if it's possible:

Bridge channels 1&2 and 3&4 to power just the front components (150Wrms each), keep the sub the way it is, and run the rear speakers off of the deck. Now I know many of you will say why bother with the rear speakers. Well, my wife likes the sound of the rear fill.

So my question is this, can I provide signal to all six channels of our amp with only the front outputs from the deck/LOC? Can I split the RCA's coming out of the LOC without any significant drop in performance?

Here is a diagram of the amp's inputs:

Any help would be greatly appreciated [img]graemlins/bow.gif[/img]

run the Front speakers: JL Audio 6.5" VR series components with the amp
and
run the Rear speakers: JL Audio 6" VR series coax's off the Head Unit

why not get two amps

definately run the two LOC's.The front LOC,for the front channel.The only thing that you may need is a set of RCA y-adaptors.some amplifiers when bridging use only the left input,some use both(l+r).The adaptors will have two male one female,one for ch1+ch2,the other ch3+ch4.The other LOC for ch5+6.If the amp comes with the remote bass gain use it.The extra control on the sub will be nice!If there is no remote gain included,the Canadian distibuter is in toronto and any dealer can get it for you next day.
Tuning the system is a little backwards.Start by setting your rear speakers first because of the lack of adjustment(mid listening level).Now use gain 1+2 for left,3+4 for right,make sure there ajusted together for front stage.Its always a good idea to use a meter on the outputs when running different outputs in sterio.you can get it darn close by ear.
Blend in some bone crushing bass via the amp gain.remember to not go crazy with the gain as the remote gain will be used for fine tuning

I don't want to run two amps.....too much money, and I'm a bit short on space.

Where exactly would I use the Y-adapters? I basically only have two channels to work with as inputs into the LOC, and need to feed the amp four channels. So would I take the pair of outputs coming out of the LOC and then use the y adapters? If so, will that have an adverse affect on the sound?

LOC output to Y adaptors to amp.No loss in sound.Try it out and tell me how it sounds

Cool, I'll give it a shot over the week-end. Thanks for the help!
