How do you bypass the factory amp? I got a harness from Crutchfield for the deck. When I installed it when playing on cd the subs would only play. If the radio was on the speakers would then play. So I called the help line and they said i need to bypass the factory amp. This is a leased car so I don't want to be cutting wires up. Does anyone make a harness to do this. Thanks for your help.

 

The only way to bypass the amp would be to go directly from the plug on the radio.

 

What do you mean.

 

To bypass the amp you would have to run speaker wire directly from your new headunit to the appropriate speakers. A headunit won't be able to power the sub by itself, however.

 

Send me an email ill forward the diagram crutchfield sent me preatty much you have to cyt the plug off the stock amp and splice the wires not hard just the amps a bitch to get out clmbngfrk18@hotmail.com

Edit: you dont have to go from the HU you can just take the in on the amp and connect to the out

 

PLEASE FOR THE LOVE OF GOD TELL ME YOU DIDN'T TRY TO BYPASS THAT AMP!!! you messed up doing the install very common mistake i've seen lots of new installers do this...the reason you are not getting any sound out is because you have the power antenna wire hooked up to the remote turn on wire your factory amp is only being turned on when you have the radio on look at your wiring on the harness for the radio you should have two wires one that is blue and one that is blue and white it sounds like you have the blue wire hooked up which means you need to switch it w/the blue and white wire the blue wire only has voltage when the radio is on fm or am the blue and white wire is hot whenever the cd player or radio is on...no need to bypass

 

I never did the bypass because i didn't want to be cutting wires. if this fix works man you are a saviour. Thanks a bunch.

 

Well I did it and it works great. Thanks alot. The people at Crutchfield know jack **** and want you to cut up your car. Losers.

 

lol no prob glad i could help just curious do you have the pioneer system? and if you do did you lose ur fact sub when you hooked it up

 

man that sux wish i had know that earlier ohh well got system any way why use the stock amp

 

everything works just like it did before even the factory sub.

 

I hooked up my subs using the rear 6x9 adaptor thingys. I get bass from all 3 of them...and nothing had to be cut. But I might use my Pioneer actual headunit to make everything neater.

 

i dont' have a pioneer system in mine but crutchfield told me if i did that i would have to run new speaker wires to every speaker from my aftermarket headunit and that i would lose the subwoofer

 

ok so what this thread is telling me is that even though i have the pioneer system i don't have to bypass the amp at all? Just buy my aftermarket headunit (so i can play my ipod) from crutchfield, use the stuff they send and make sure that the harness is hooked up correctly? because if that is the case i'm gonna make sweet sweet love to every single one of you guys.

 

im doing the same thing wich wires did you tap into? what color? im so trying to find out
thanx

 

so where is this pre amp at i have all fusion speakers and amps and a kenwood double din nav .and every once in awhile i hear a crackling noise regardless if the amps are hooked up. im assumming the preamp is doing this so i am gonna bypass it completly. any body else have this problem ? also if i touch the speaker wires together i get a pop noise even thou theres no after market amps hooked up

 

Hi, can you help me do this? i'm planning to put mono sub to my pioneer HU too myself and i have no idea about it. I mean, wiring diagram

 

k well if u want to keep your speakers and sub witht the fatory deck just by the cheap harness but since the amp is 224 watts and your deck will be pushing out 50 watts per speaker and sub you will need to use rca cables to keep a low sigle so that your speakers wont blow so on the harness on the speakers u will want to splice in the rca caple to the spkear wires then hook them up to the head unit

 

thats if u dont want to add an after market amp for speakers and it works perfectly i got pictures of what i done if you need them just let me know

 

holy 2005

 

what year is your car? and what model? what harness did you buy is it a metra? or the 150 doller one?
k so if you have any other harness then metra you will need to re-pin it, but first to by passs the amp on the harness you bought you want to splice in rca caples to the speaker wires on the harness the red rca is always right and the white one is left, when you cut the rca the wire that is inslated is postive and the wire not is negetive so, front left speaker you would take the white rca and put the negetive wire on front left negetvie and the postive wire to the left front positvie once your four rca cables are spliced in hook it up to the deck but dont run thos wires to the harnes all you will be is running is acc,ground,power and the orange wire im pretty sure forget about the speaker wires.
if your have any questions reply i also have pictures of what i did and my car is an 06 ss/sc but if your car is an 07 ss with pioneer you will need a 150 doller harness
