amp not coming out of protection
Amp is not coming out of protection...i hook it all up 2 days ago, it worked for 30 seconds than i turned the car off and arranged everything and put everything back together.....started car 10 minutes later....when for a 10 minute ride (worked fine).....got back in to come home, half way back it shut off and went into protection....after it sits a while it might come out of protection but if you turn the volume up alittle it will click and go back into protection....it last came out of protection last night....turned it up(went off)....ever since then it's been in protection (almost 24 hours).

i just hooked up a Boss 3600 watts Max, and a Pioneer Premire 3500 watt max(1000 rms)....the amp has only one output on it for one sub....and the amp is 1 ohm stable....the sub is wired as 1 ohm.......anyways.....

i hooked them up in a 06 equinox with the stock radio still in it(so i used a line out converter)...but the line out converter is only hooked up to one stock speaker because their is only one stock speaker in the far back.

i hooked up the wires as said, but not sure if it's for 2 subs to be hooked up or not (cause i'm only hooking up one).....but the wires coming out of the line out converter are....
RED = hook up to 12+ on the amp
Blue = hook up to remote wire control on the amp
Green = hook up to + wire line on the car's stock first speaker
Grey = hook up to + wire line on the cat's stock second speaker(which i just hooked up to same wire as green
Grey w/ black stipe = hook up to - wire line on the car's stock first speaker
Green w/ black stripe = hook up to - wire line on the car's stock second speaker (which i hook up to the same as grey w/ black stripe)
Purple = hook up to green w/ black stripe (this one is just to get a 12+ volt for the remote turn on to work on amp)

did this all.....hooked up rca cables to amp and other side to line out converter...

power cable to battery and amp (w/ breaker) is good

ground is good

can anyone firgure this one out, or help, thanks

Did you buy the amp brand new or used? Are both amps in protect? Did you multimeter your power and ground? When the car is running how many volts is your battery putting out? How do you have your amps grounded? The line output converter wouldn't cause this I don't think. It has to be your power or ground wire. What gauge power/ground are you using? How many subs are you running? Are they DVC (dual voice coil) or SVC (single voice coil)? Is it DVC 4 ohm or 2 ohm? SVC 8, 4 or 2 ohm?

no, my gain is lower than 50%

only one amp is hooked up

but i did find out the problem last night, soon after i did this thread.....the ground connection was at a bad spot....i moved it to a different location and works great now....(this was actually my girls car)...and i have the same subs in my car (2 in mine, `1 in hers)....hers is louder than mine and everyone who has been in my car has said that it's the loudest they've heard....

i have a MTX 3000 watt max 1000 rms amp
with 2 3000 watt max 1000 watt rms pioneer premier champion series subs

she has a Boss 3600 watt max 1350 rms @ 4 ohm (they both(amp and sub) at 1 ohm though)
with one 3500 watt max 1000 watt rms pioneer premier champion series sub

I fucking knew it was the ground. Every time. Every fucking time. Make sure its fastened to an unpainted metal surface.

I personally run an entire Alpine setup.

2x Alpine Type R's each wired at 2 ohms
2x Alpine MRP-M450's each pumping out ~400 watts per sub.
1x Alpine MRP-F250 powering my door speakers
1x Alpine CDA-9857 in the dash
4x Alpine Type S 6.5's in the doors and rear deck
1x Clarion Eq-74 Equalizer in the dash
2x Rockford Fosgate 1 Farad Capacitors

Gives me a big fat boner every time I turn it up to 21.

Hey snyder,

I currently got a 500/1 jl amp with the 10w7 with HO box.

What do you think of the jl door speakers, like mids and highs, currently running stock alpine. If you ever heard them?

The alpines i got with the car, but wanted a uniform feel throughout the car.

problem, the amp works great, BUT when you turn it up TOO loud it will shut off, go into protection( i believe), but the i'd shut the car off right away, start it back up and it'd turn right back on if my music is turned down alittle bit that is..... than what is it?....i do have the ground wire from the cap AND the amp AND the smally tiny ground wire from the Line Out Converter all at the same ground bolt....would that have anything to do with it? the gain is set at 50% right now....and i also have an Output Control knob on the amp...what do i set that at? it's at half way right now

the amp/ sub does get very loud, but it's when i turn it louder

What gauge power wire are you running. My guess would be its not thick enough. Here is a chart to use:

http://www.the12volt.com/info/recwirsz.asp

Whats your RMS output of your amp? At the shop I used to work at we would never use those bass boost knobs. Too many systems came back with blown amps/subs when we installed them. If I were you I would head into my local shop and ask them if they could set the gain for you. Normally how the gain is set is as follows:

Turn the gain to zero.
Turn the volume of the system to the maximum listening volume.
Slowly turn the gain up until the sub barely starts to distort.
Then turn the gain down a notch.

Having everything on the same ground can cause a ground loop. You know how in some cars you can hear the alternator whine through the speakers? Yeah, that is a ground loop. Other then that there is no problem with it.

I personally believe JL is over rated and over priced. Unifying your car stereo with all the same equipment isn't always the best solution. It all depends on what you want the end effect to be. I wanted a good combination of sound quality and loudness. I personally believe I achieved this through my set up. Some people like it some don't. It really comes down to personal opinion. If you feel you are getting a good deal and the sound is what you are looking for then by all means feel free to do JL through out the car. However make sure you dont limit yourself simply because you want the whole car to be JL Audio.

There is no reason to sacrifice quality for a name.

Whats your RMS output of your amp?
1320 RMS

so, then in other words, your saying that it's just too much power going at it?

i have the wiring kit :

Earthquake 5000 Watt/ 4 Gauge Amplifier Wiring Kit Amp Wire W/ RCA

the SUB is 1000 Watt RMS and 3500 Watt Max

Amp is about 1320 Watt RMS and 3600 Watt Max

It is impossible to send "to much power" to an amplifier. The thicker the wire the better off you are. You could run 0/0 wire to a 100 watt amp if you wanted to. 4 guage is not thick enough. You should be running either dual 4 gauge or 2 gauge. A quick fix you may want to try is as follows : What is the amp rating of the fuse you have under the hood? It should meet or exceed the total value of all fuses in your amp added together. So for example, say you have a 60 amp fuse by your battery but your amp has 4 x 20 amp fuses. You have just bottle necked the system. Usually this will cause the amp to pop under the hood before the amp goes into protect but not always. Check that first and lemme know how it goes.

what do you have your gains set at? make sure your amp is on lpf, freq around 80hz... you say you are using the stock head unit? while ive not personally installed a line out converter in a car, i do install stereo's on the side and build boxes and what not as a passionate hobby. for anything over 600rms you should use Real 4 gauge wiring.. take a look at www.knukonceptz.com , great prices and top notch quality products. also, are you sure you have your subs wired right? most companies add a wiring diagram to their subs. if not you can head over to JL Audio's website for a good pictured wiring diagram for svc and dvc subs... what is your voltage running at when you have the stereo turned up? in order to find this out, take a digital multi meter to the battery and get the voltage. at idle it should be 13-14volts, with the car off it should be around 12volt. if you have your car running with the stereo up and its dropping below 12volts you need to turn it down. you are inducing a heavy load on the cars alternator, its not able to produce enough current to supply your demand. an easy upgrade you can do is called "the big 3" you can head over to www.realmofexcursion.com and do a quick search and find a sticky of it, its a great upgrade and really makes a difference.

anyways, your amp is either clipping, your having major voltage drops, or faulty wiring. or a mixture... go over your wiring and electrical.

what do you have your gains set at? 50%

make sure your amp is on lpf...is that the low pass frequency? because how is that turned on, or is that on all the time, i do have a knob for that which would be the freq. which is at about 100hz

you say you are using the stock head unit? yes

. for anything over 600rms you should use Real 4 gauge wiring..

isn't what i have 4 gauge wiring?

also, are you sure you have your subs wired right? yes

what is your voltage running at when you have the stereo turned up?

instead of useing an multi meter, can't i just look at my digital cap? if so, i'd have to get back to you on that

What is the amp rating of the fuse you have under the hood? it's 5000 watts, suppose to be anyway, it came with a 5000 watt wiring kit.
