Help with car stereo

[Trouble]

I need someone who knows all about car stereos and subs and stuff to be so kind to have a look at mine. In surrey or close to me. I have a 10 inch sub that just stopped working. All fuses look fine. I know nothing. Thanks

There is a red light on the front of the amp. My brother in law is going to take a look aat it this week, but I miss my sound now. All the other speakers are on and woring and I was told power is getting to the sub. Wold something called the capacitor be broken? Saw it online when I googled.

what kind of amp? In can message my buddy he works for audio video and is a genious!

IMO, that means there is a ground issue, it is tripped the power shut off feature. alot of amps have these to stop it from being blowen, if there is power going in with no where to go ( incompleted ground) it will also do this.

I would try removing your ground wire, taking fine sand paper and cleaning the contact point.

if power is getting to the sub, but transfring it, its an amp issue. check the ground for sure!

if you had a cap ( capsator ) it would be a tube, with two wires coming out of it... it works like a second battery, if that is the case, you will want a pro to fix it. I have heard of caps blowing the trunk apart when they short out.

do you have a multi meter. if so, i can walk you through it and troubleshoot relatively quick

amp is like 18 years old 4 channel but I had it fixed by a professional 4 years ago for $60. It was also made into a 2 channe from what I was told. Should of just bought a new one from Clarence for $85 back then. The sub is a kenwood from Clarence (BCAquaria). The box is just a regular box. Was working all fine. Thought my kid kicked something but all looks hooked up. I was going to go to Audio Video today but they have closed shop here. I used to know a guy that managed the Burnaby store. I can take pictures if that helps. One day I will look into getting more then just 1 10" sub.

so is it just the sub that's not working ? If so check the wire on the back of the sub box . Can you get at the speaker itself? If you can place you thumb and index figure on the small center portion of the speaker and apply just enough pressure to make it move in and then release it .it should have free movement in and out. If not its fried or has grit between the magnetized steal shaft and the copper wrapped cylinder that slides up and down it moving the speaker cone to create sound waves...or some crock n bull like that.
you could check it as well by using a 9 volt battery and blip ( quick contact on,off ) the sub speaker with a couple pieces of wire ...this will cause a sharp snapping sound and move the speaker cone unless there is a break in the wire ....if you don't have a multimeter that is.

If theres a red light on the amp now it means its in protection mode, Usually due to a fried sub with melted voicecoil. Or if youre lucky one of the wires has shorted out, Could be as easy as the speaker wires touching together(you did say your kid kicked someting). Unhook the sub from the amp and turn the key off and on and see if the red light turns off, Most amps will have a red light for protection and green for power on.

Did it do anything unusual just before it shut off? did you smell anything burning or melting? If the voicecoil melts you can smell it fairly easily. With everything off try lightly pushing the sub in and out with your hand, If it feel like its binding and sounds scratchy it means the sub has melted the voicecoil inside and is toast.
