    all right i have a 99 escort with the factory tape deck and 6 disk cd changer. this is my commuter car, so i want to spend minimal money. i have an old 300 watt amp and 10" sub w/box that i used to have in my old dakota laying around. i would like to wire it up in the trunk. anyone ever tap into the rear deck speakers for signal?? or am I better off tapping into the radio harness with a line out adapter?? this is probably a spring time project, but i thought i would start acquiring materials.

    thanks for any help...

    dont tap into the rear speakers.. it loweres the impedence on the deck and a low impedence means high current which inturn means hot wires. and will fry the deck and a possibility crisping your poor ride.

    i have been doing car audio for 13 years and never heard such a thing.

    installing an amp on the factory unit is just stupid! if you want to do it right i have a panasonic deck with a ford harness already wired to it im selling for 50+ 10 shipping. it will get you down the path properly.

    my dad used to install car stereo's and car phones for 15 years and told me not to do that along time ago when i was a youngin and told me it loweres the impedence of the deck which can fry it the proper way to add more things to existing is a crossover

    you are misunderstanding your father.

    a crossover is not going to do you a damn bit of good with out a high low convertor. it you want to have a factory headunit and run stuff off it the "proper way" would be to get a JL audio cleansweep or something like it. other wise jack the factory deck and go aftermarket. a high-to-low convertor is not going to ruin anything or they wouldn't make it and sell it. a hig low convertor simply takes signal. its not drawing any power from the headunit. im willign to bet the hig-to-convertor is a very high ohm load so it balances out to not ruin anything.

    Not saying this because i'm a prick (though i very well may be), but either you or your father or both don't understand at all the relevance of impedence in an audio setting.

    Yes, it is true that you shouldn't just tap into speaker wires and run new wires to a sub and do nothing else. But you explained the why completely incorrectly.

    my amp actually came with a connector and spliced wires to hook up the speaker wiring to the amp. find an amp that has the connectons like that.

    Once it gets warm out I will hook my amp and sub up to the factory radio. I know it can be done, either direct splicing or i buy a line converter. Thanks for the help, but I think we need more actual technical facts around this place....

    here is a technical fact you noob. its going to sound like crap!

    i have done plenty of installs in my history and all of the ones i was asked to use a high-to-low converter in i disliked the results. yeah the person was happy because it "banged". but the sound quality was sub par.

    same here...i mean if its a commuter, that means your gonna be spending a lot of time in it right? just go get an aftermarket deck to hook it up, itll be a hundred times easier and your sound quality will be soo much better. basically listen to neuman..

    Hi/Low's suck, they only give you a false sense of audio signal, and just makes everything go boom boom...

    it doesnt matter where you use the hi/low UNLESS you have a system with a factory amp.. then youd wanna use the wires AFTER the amp before the speakers, NOT at the radio...

    otherwise it doesnt matter..

    if your going to have subs get a radio with sub control, it will make everything sound alot nicer..

    I know what the OP is going for here - it's the same thing I did in my Cougar when I first bought it. I was 16 and didn't have the cash to drop on expensive equipment.

    I had a factory cassette player HU, Pioneer front speakers, factory rear speakers, a Scosche SLC-4 H/L converter, 300w Jensen amp, and a Jensen 12" sub.

    I tapped into the rear speaker wires (at the HU to avoid too much attenuation) and ran wires to the H/L converter in the trunk. Then from the H/L to the amp, then finally to the sub.

    It will "work" this way but as stated, sound quality greatly suffers.

    I also noticed that even with the amp, there seemed to be tons of draw on the rear outputs because the rear speakers didn't sound as clear when the sub was pounding. I never had any heat issues with the wiring, but the head unit got super hot when cranked. There was also a lot of voice that could be heard through the sub.
