ok what happened was i bought an amp off a mate i put it in my car yeah running sweet so i go to a mates house and we were talking **** and it came up with the sugestion for me to take our my 2 JL's and put in his 13.5'' JL w7 (1000 watt rms) so we did that and my amp is a 800watt rms wasnt upto scratch but it was working fine so after a couple of days of driving around being a loser with the stereo up lol i go past my brothers work to wash and detail my car i get there with the music up all good i was my car so i sat down had a smoke inside his work and he goes go get your car into the factory so he brings the car in with the stereo up and out of nowhere the bass stops so i go have a look at the amp and its on protection mode so im like turn the car off and turn it back on so he did that and nothing so here i am confused why isnt it coming out of protection mode i have changed the fuses so everyone knows please help me thanks guys appriceate it Some original photos have not been recovered yet.

Is the positive and the negative around the right way? The same happened to me once using second hand subs. The previous owner had the subs wired around the wrong way, positive to the negative and had reversed the polarity. Making the sub bounce inwards instead of outwards. Which made the amp go to protection mode. Also some subs which have a lower ohm rating than the amp will over heat your amp making it go to protection mode. Does the protection mode go on straight away? Make sure your ohm on the amp is the same as your ohm on the sub. If you have a 4 ohm sub on a 8 ohm amp the amp will over heat or shut off because of the load on the amp. You must match amp ohm's with sub ohm's!!

check and clean your amp earths! similar thing happened to me a few weeks ago, the amp earth looked fine so i left it. but i had a 3 vold voltage drop across the earth. clean it with sand paper even if it looks clean

edit, nevermind, i thought you were running all 3 subs! lol my suggestion still stand though. how did you wire up the sub? the W7 runs dual 1.5ohm voice coils. if you wired the sub in parallel it would have presented a load under 1ohm which would really push the amp! heres a diagram showing how it works Some original photos have not been recovered yet.

i got my subs hooked up to another amp like a cheapy one ive had that for a few months then i got my other amp when i got some cash and like then put it in with the w7 and then went into protection mode and then i put my other subs into it and it stayed on protection mode now i dont know what to do should i clean it or what??? thanks guys

id say you fried your amp man you need to tell us how you wired up the sub and also tell us what amp you were running with the sub

umm well my ive had my subs for about 3 yrs now with one amp and its been working put them on the other amp the 800rms monoblock that amp stopped working and i put my subs on the old amp and works fine

yeah we're not talking bout your subs or the other amp seeing as your not really following what im saying, then id say you wired the W7 up as parallel which would place a load lower than 1ohm on the amp. basically your amp was working far too hard for its own good and fried itself.

lol now that makes more sence sorry mate but i get ya now cheers Some original photos have not been recovered yet.

all good it gets a bit confusing lol basically if the amp isnt coming out of protection mode, even with no speaker connected, then its toasted! Some original photos have not been recovered yet.

Had a friend of mine who placed a 4ohm sub on a 8ohm amp. Within 2 months the amp wouldn't stop going into protection mode. Anyway the technician said you have overloaded(fried) your amp because of the extra load. Please, Please match your amp ohm to your sub ohm. If not place a higher ohm sub on the amp, less load then. Small ohm = More load. What's the ohm rating on your amp?

i wouldnt have a clue ill have a look tomorrow cause its still sitting in the car ill find out and let ya know cheers guys you are all champs Some original photos have not been recovered yet.

just get a brand and model number, will be enough to answer the questions id be taking it to get repaired though, not much you can do now lol
