I tried using the amp bypass on my 93, have some questions

[unpredictable1]

I found with every car I owned that even just upgrading the deck made the stock speakers sound better. This was the case with my 93 as well, but I decided to try and install the amp bypass harness I had.

What resulted was the worst sounding system I ever heard. By far and away. Very tinny, hollow sound. (yes I know the sub is now not functioning at this point but this was ridiculous)

This has kept me from leaving installed and upgrading my speakers, and I've gone back to stock setup with the exception of the new deck. Anyone shed some light on this for me?

Thanks!

I think I might have the answer myself from an old post I had placed last year. Is it because the deck can't properly run the stock ford speakers like the amp does? Therefore when I bypass the system and the deck is powering the speakers directly - its totally out of whack?

 

[unpredictable1]

wow, not one bite at this?

Mine was the same way, but only in the front channels. Ford used terrible thin wiring, just rewire the speakers with some good gauge wire and your problem should be solved.

 

[unpredictable1]

The factory ford wiring should be well enough to enough to run speakers off an aftermarket deck. Now if I had an amp in there to power the speakers that would be a different story

I don't get it

I don't understand the big deal with bypassing the factory amp. I removed the factory tape deck and replaced with a JVC disc player, swapped out the OEM speakers with some infinity's. It sounded great. Later that year I added a box of dual subs run off a Kenwood amp. People at the stores were like "you have to buy this factory amp bypass too or your system won't work well or sound right", I shrugged em off cause I was too lazy to disassemble the back paneling to expose the amp and install the plugs of the bypass. My sound and volume has never been better. I say screw the bypass and leave it alone, you might be happier if you did in the long-run. I am!

As far as i can tell......bypassing is not an option, its a requirement, at least for my 96 anyways....if you don't bypass the factory amp then you get no audio. Are you sure you have the premium sound? The basic package doesn't need bypassing because it has no external amp.

 

[scottswierenga]

I know there is, I've seen it during subsequent service

 

[ap81590]

How did you get it to play without bypassing? Is it different on 2nd gens and first gens? Mine was silent until I bypassed the factory amp.

 

[unpredictable1]

I installed good pioneer speakers in my old first gen after i had a new deck put in, the sound was marginally better because you are still limited by the power the amp is sending.

 

[scottswierenga]

It seems to be different for the 2nd gens than for the 1st from what I am hearing. I'm not sure how it was able to work in mine...I just hooked up the wires at the headunit and it all worked fine. If I remeber correctly I had to double tap the blue "signal out" wire coming out of the head to provide turn-on power for both the factory speaker amp and also for the subwoofer amp. Never had a porblem once.

P.S. I don't know didly-squat about Ohms, hardly nothin about Amperage, some about Voltage, and alot about troubleshooting. And the funny thing is....I can make it all work just fine I wouldn't have it any other way!

your right ibrown your factory wireing is good enough even with a aftermarket amp not like you gonna put 200 watts to them, and scotts well you replaced the speakers with aftermarket ones thats why yours sounds good the upgraded oem system works with the speakers at 1.8 ohms when you replace the head unit you are sending 2 to 4 ohms normally and if you didnt replace speakers which are at 1.8 ohm as well you get bad sound! ohms are a unit of measurement for resistance the radio needs so much to "run" right just as your motor needs so much backpressure to run good. the aftermarkets you put in ran at 4-8 ohms so everything on your car is in co- op if you ibrown want to use your old speakers you can just buy the right resistors to put them in co -op or its easier and better in my opinion to just replace oem with good after market. and the reason you bypass the amp on these is because the oem radio sends a small signal to the amp which then boosts it then sends it out to each speaker accordi. if you dont bypass the amp wont come on and all youll hear is weak sound when turned way up now i hope that this makes sense to all of you b/c this particular forum is about all i know anyone want to help rebuid a tranny!!! thats my weakness! :fire:

Exactly, so in not so many words if I plan to replace the factory speakers and get the most out of them with my aftermarket deck, I run the amp bypass and just use the stock wiring which is more than adequate for this basic setup.

 

[jeephater#1]

u got it i just wanted to make sure you would understand why and how it worked but you got it know hope the install goes well!

 

[unpredictable1]

I'd be going 3 way pioneers in the front, 2 ways in the rear doors, all this powered by an aftermarket deck with the amp bypassed should sound better than my aftermarket deck running through the amp with stock sub and speakers.

I should be doing this this summer.
