i have a typical 50x5 200w run of the mill jvc deck

my question is this

can i somehow harness the power of the rear channel and give it to my front door speakers to get more power.

my 6x9s are not even hooked up right now and i dont notice too much of a difference, so is there any way i can give like 40rms to my door speakers and get some nice clean highs?

Not that I'm aware of.

Furthermore, if you're using stock speakers, more power could very well kill them.

No deck that I've ever seen has an internal "bridgeable" amplifier - deck power is the worst form of power you can give "any" speaker. That 50wx4 printed on the front of the deck is "peak" power.

Get yourself an amplifier that has a real 30wx4 or more and it will blow away what your deck is boasting. (its not just your'e deck either, all of them are rated at peak power - or what I like to call JBF rated - "Just Before Fire" !!

yea i know its rated at peak, im guessing it is pushing anywhere from 17 - 22 watts rms.

the reason i ask is cuz i know that 30+rms power is all that is needed to give u amazing sound from a door speaker.

and the speakers are not stock, they r some crappy aftermarket ones.


are there any types of speakers that can accept two power sources to different channel and play em both?

or is there any way i can cram 2 speakers into a door easily or do something like that?

Okay now your'e scaring me - what are you trying to do ??

If you get a good amp - there wouldn't be any reason to have a speaker that will take two different power sources.
Trust me, you dont want to do what you may be thinking of doing !!

Doing something different from the way it's supposed to be done is the quickest way to blow sh*t up !!

If you get yourself a good pair of speakers and a good clean amp - you will have good sound - trying it any other way is a lot tougher. Simple is better in alot of cases - I know lots of guys who try "cramming" a boat load of speakers in a car trying to get more sound.........sometimes, more is less !! You can get cancellation and phasing problems.

Keep it simple - at least when your'e starting anyway !!

Actually, Pioneer made a series of decks that you could bridge the deck(MOSFET) power for a subwoofer, but I believe they have done away with it. It was a great idea for people that wanted to add a subwoofer but couldn't afford an amplifier.
Thanks Elliot for the reminder of that !!

I think what you are trying to do is bi-amp a pair of front speakers using the 4 channels from the deck....

You can do this with a slight modification to your coax speakers. Leave the cap in place on the tweeter and use the 'fader' to fine tune things

Quite cheesy but would work.

FYI:
Sony made a couple of decks with Bridgable outputs a loooooong time ago.
They had a "little" amp bolted to the back of a couple of Shuttles decks.

Now I am REALLY dating myself

I remember the Pioneer decks from the early 90's (Supertuner) that were rated 7 watts by 4, or 15 watts by 2. My DEH730 from 93 was set up like that......
