Help My Mids Arent Working - Toyota Nation Forum : Toyota Car and Truck Forums

GORILLAKEV · 08-04-2009, 06:48 PM

So this morning i turn on my car and only the highs are working? whats going on with the mids because last nite they were working perfectly fine but now they are not working. i checked my trunk and saw that one of my wires from the loc got disconnected maybe it shorted something out. i checked all the fuses and nothing was broken. now what do i do is it the factory amp that is broken. i cant even get my bass working because i hooked it back up and there seemed to be no signal going to the loc to the amp. so i disconnected my subs took out the loc and took the power to the amp out of the battery and still nada. any advice would be greatly appreciated. 2007 toyota camry jbl system. next thing i might have to do is take out the seat and take the amp out see if any internal parts are burnt or test them with my fluke. or is there a warranty that will cover this (i can take all my wiring out and take it to the dealer if there is a warranty). thanks for any advice given

what's a loc? Usually when you short your amp depending, on the fusing on the amp(stock amps probably wont have fuses at the amp, Idon't know). By experience you can actually damage your amplifier. So there is a good chance your amp is damaged or those channels are blown. I would get a new deck and run your speakers off the new deck, which will provide you with more power then stock anyways. I currently run my rear speakers off my aftermarket deck and then run my separates from my aftermarket amp. I try to stay away from that stock amp and stock deck. Shitty clarity! It's not worth repairing or even probing with your fluke to try and repair that crap. That's just my opinion, good luck! Get a new deck, if not I have a old Rockford Fosgate 4040 DSM amplifier for sale that one channel of the four channels is out. You can repair it definitely cause my wife spilt soda on it a while ago. So you probably just have to clean it, but it was a good excuse to get new amps or use newer amps for my system. just a thought!

ditto on his post.

Stock decks and amps pretty much have no power and they suck in quality. It's not worth repairing unless you like that stock look.

Most amps have fuses on the amp and still most car audio shops will put another fuse near the amp. Usually that fuse is near the total number of fuses on the amp.

You can do what the other guy posted which is have a 2 channel power your front speakers which would work well if you went with separate component speakers, then have the aftermarket deck power the rear speakers. Usually rear speakers are just for fill but if you regularly have other passengers in the back, then you can wire your rear speakers that way.

a loc is the line output converter used for using the stock deck. i checked yesterday to see if the problem was a bad speaker also and its a no go on that idea because i tested it and it was still giving an ohm load then tested the speaker on the another car and it still works. so i thought it was the channel on the mids blew so i tested one of the speaker wires with my fluke and nothing happened no wattage anything the amp is not sending a signal to the mids. sucks now i got to figure out how much a new deck is and get an amplifier bypass wiring harness, and mabe the thing that lets me still use the steering controls and a 4 channel amp maybe. or just buy a used stock amp (if i can find one) so far ive found an amp for the prius but not sure if it will work for the camry. thanks for the info if any knows about a warranty let me know

maybe it is time for an upgrade also i should just get a new component set and a pair of 6x9's for the trunk and a two channel like gameguru said and that way i dont have to run two loc's for two amps. i was already planning on it but later on down the line but now since this happened gotta go the route you guys were talking about. i know for a fact that it will sound better because the loudest on the stock stereo isnt really that loud and it just ties in with the subs i was running . sucks and i just got a new sub/ mono amp setup just sitting now cant even get my loc to work off of the mids signal. damn im just rollin with highs soundin like a old stock mini truck lol....i'll update you guys when i really figure out what the game plan is...thanks again dr _green and gameguru

nah stay away from those locs, anytime you try to convert your signal that is a point of entry for noise, voltage drop(poor connection), or something bad. I would advice if you have one loc, just stick with one and get a splitter and split the signal.

If you want a signal for your loc right at this moment then you have to splice the feed going into the the stock amp. this will give you a full range signal. but now i don't know about your factory warranty, i think it voids if you cut factory wire. i would just wait and get a new after market deck and then you don't need your loc and run clean rca's to your amps and speaker wires to your speakers. glad to help, hope your system is back and running!

i tried tapping into the rear tweeters to give me a signal and nada epic fail no signal to my sub amp....so i am looking and deciding on a new deck and since i am putting in a new deck does this bypass the jbl amp i assume with the proper wiring harness... or with a new wiring harness i have to rewire all the speakers to the front or is the wiring harness plug n play and all speakers are going again(remember im not goin to use using the stock amplifier any more)...if i have to rewire everything to go the deck it is fine with me because id rather not cut. if i decide to sell later on and keep my sound system. thanks again

Yes the new deck can by pass the amp, but you got to run new speaker wires to your speakers. The front speakers is fast, but just the rear is a bitch. But if you can locate your stock amplifier, then you can splice your wires from there and then feed your rear speakers from there. I don't know how the front is wired, so watch out because it might be that there is a bass blocker inline of the tweeter or something. I have no clue. I would rewire the front and then keep the stock rear wires. Good luck!

alright guys so im getting my new deck tomorrow hopefully all will go in just by plug and play...ok hers the thing i am goin to buy a double din dvd/cd player and i am also getting the harness and dash kit at the same time...so since i have the jbl optioned camry i wanted to wire the front tweets and rear speakers and then amplify the door speakers with a two channel...so my question is will that harness work for just hooking the speakers alone or does it still process through that stock amp..also where can i get that wiring color code chart for a 07 camry jbl equipped i found it on here before but for some reason when i searched for it i cant find it again all i remember crutchfield made that chart.

What the purpose of the haness is, that the deck gets power. You don't have to wire the speaker wires, especially if your wiring an amp. I think you might be confused a little. Cause, when you install a new deck you just need power, then you run RCA cables to your amplifier, then from your amplifier you run your speaker wires to the speakers. So I'm not exactly sure what your question is.

Only one concern I have for your amp that you want to load with your tweeters, door speakers, and rear speakers; Is that check the load( meaning ohms) Make sure you don't go under your manufacturers recomendation. Usually 2 ohms is the lowest in regular 2 channel amps.

Good Luck! Let me know if I didn't answer your question.

GORILLAKEV · 10-09-2009, 02:07 PM

i was goin to run the front tweets and the rear speakers through the deck, then i am goin to amplify the front door speakers...i think the question is will that work in my setup because it has a stock amp or if i just hook those speakers up to the wiring harness it will just go...well if it doesnt work i'll let you guys know.. i dont know maybe its me i might just be confusing you..i'll give you updates once it is hooked up

okay, still the loading for your amp is a question. I would check to ohms loading when you parralel the rear speaker and tweeter.

But as for the wire harness, when you just hook it up it will work. but I would bypass the factory amp and rewire the front speaker.
Think about it, your going to be feeding a powered signal to the stock amp, which the stock amp wasn't designed for. Good luck

GORILLAKEV · 10-10-2009, 03:15 AM

yeah i thought about it too...makin it hella complicated when its not sujpposed to be.... i am going to disconnect all the plugs from the stock amp and just cut the wires i need to hook up to the new deck...then check the ohm load but i remember it was 2.2 ohms for the front and 2 for the rear but i 'll double check it.
thanks again

HEY HEY, WATCH OUT for cutting FACTORY wires, that's why you splice the wiring harness for signals. Any modifications to the Factory wires will void your warranty(as I was told). Except for splicing Factory speaker wires, should be fine, they are easily replaced. Just watch where you splice. Good Luck!

2 Ohms for the rear speakers and the tweeters? Usually Decks in general can't handle less then 4 ohms loading in resistance(Can but life of deck will go faster). They can have a higher impeadance but not lower one. I would re think how you configuring your speakers, maybe if loads are not coming out. Also I thought our rear speaker was rated at 8 ohms. My rear 6x9's are 8 ohms, if not 6 ohms or something like that.

GORILLAKEV · 10-22-2009, 05:52 PM

i opted to just clip everything and just rewire it...i know i just voided the warranty but its too late now...well i hooked everything up and it was just a real big hassle got it done though it sounds ok i need to get a crossover for the front tweeters. but i will be adding a 4 channel in a couple of weeks to take the load off of my deck.. i will post pics soon once i resize them..thanks for the help guys
