So, the other day i went to best buy and had a sub and amp put it, it was a sony xplod 1200W and and a sony slim-line 1200W subwoofer, and i left best buy and when i pulled outta the lot i turned up the volume, thats it, and i got halfway home, and now....no subwoofer and the protection light is on, i took it back and asked them and they think i blew it, is that possible, i didnt even mess with the bass

 

if the protection light is on the amp just check your wires, my l7s did it to my 500 watt amp but thats because the amp was working so hard, but thats kickers power hungry subs.... but thats what you get when you buy cheap stuff

 

all the wires are attached fine, where should i check???

 

Does it work now? Usually the amps get hot from working too hard and go into protection. Or maybe you fried some internal components. I'm sure someone with a wealth more knowledge than me will come along shortly.

 

it hasnt worked since the day i got it installed (monday), i dont know whats wrong....i cant believe that i blew the sub by just turning the vloume up, that makes no sense to me

 

I don't think it's your sub, I think it's your amp. Return them both and get new ones.

 

if its not the sub, why return it? and i dont have the 'protection plan' or w/e yet

 

and i only used it for maybe one or two songs, i dont know how it could be fried already

 

thats why you dont by sony crap. its called xplod for a reason, it xplods.

 

Id just check ur wires try redoing the ground and unhook them all and reattach them. I highly doubt u blew the amp or sub. Usually a fuse will blow first.

True redranger04g, Sometimes sonys are good and sometimes they are not

 

i'll check the wires tomorrow, as its late and dark right now, and if its just wiring, then the guys at best buy are full of **** lol

 

the amps working too hard.. try and turn the gain down. better yet take that sony stuff back and get something better

 

how can it be working too hard when its not even making the subwoofer kick tho

 

alright so i looked at the manual ( who does that? lol) an dit says that if you hear the alternator, either the ground isnt connected right or...

power connectin wires are too close to rca wires or...

negative speaker wires are too close to chassis...

and the alternator squealed when i pulled out of best buy's garage, and then the amp went into protect a few minutes later and the manual says protect light comes on when there's a short circuit, is it possible that the ground came undone and is causing a short circuit???

 

They're talking about electrical noise, not actual noise from the alternator.

As far as the ground, I would definitely check that. Could be a bad connection but if it wasn't connected at all the protection light wouldn't be on.

I would check the wiring. The ground wire at the amp and the actual ground. The hot wire at the battery and also at the amp. Check the amp turn on wire as well as the RCA cables at the amp and the back of the head unit.

Also have you unhooked the wires from the subwoofer to see if the amp goes out of protection mode?

 

^ Very plausable. I guess I was assuming that the wiring would be done right. I would think if you took it back to best buy and told them your symptoms they should fix the problems. Isn't that why we pay other people to do the work so we can complain that it's not right later?

If you can't take it back and complain, I would go for the ground first and make sure that it is good. Also look for your inline fuse and make sure that isn't blown. And since your there might as well make sure your RCAs (patch cables) are at least two feet away from your power wires.

 

 

ok so you bought a sub and turned it up and now it doesnt work... theres an endless amount of things that could gone wrong. the amp might be too much for that little sub and you had too much power running to the sub... also if the amp is a one channel amp and your sub is wired to one ohm then you most likely did mess up the sub and blew it.. it could be the wiring inside the box maybe it came undone cause the guy at best buy was too stupid to press and secure the positive and negative terminal... maybe you also could have the pos wiree hooked up to the neg and the neg to the pos... but then again everybody thats punking you for buying cheap **** at that expensive place is right... you should kno better then to just buy you must research **** first...

 

im pretty positive i blew the sub, i took it apart and there was a burning-ish smell inside the box, but it was teh only one that i could find that fits in my truck without having to have the drivers seat all the way forward which makes uncomfortable driving, so i went back to best buy and had the protection plan put on it, in a couple days im going to go back and try to get it replaced, do you think they will???

 

a blowed sub would not put the amp im protection mode...2 very different things, protection mode means the amp is in danger of hurting itself so it goes to safe mood til the problem is fixed or cools down...as for the sub if it smells burnt then most likely the voice coil...i have burnt a few on my l7s but running to little air space..

 

well, the amp isnt in protect mode anymore but im positive the sub is gone

 

Yup sonys tend to do that...plus the sub is not 1200 rms its like 300rms...so you probably killed it if the amp does more then 300 watts all the time

 

alright, i went to best buy and told them it just quit workin and the guy looked at it and said its for sure blown, so he swapped in a new one and turned down the gain, which should have been done in the first place and said to come back in a couple weeks to turn the amp back up

 

Yup break in period...I only knew kickers had a break in period, that i always ignore
