today i had my truck idling and I cranked the music up so I could adjust the settings on my HU. Since I just got it all installed. It was about 3/4's of the up and I changed the song and all of a sudden NO BASS. I checked the fuse and it was blew. I was wondering what might cause this? if this helps I have a kicker kx1200.1 running two Infinity kappa perfect 12's

Did you blow the amp fuse of the inline fuse to the battery?
First thing I would check would be the wiring run. Make sure it is clear of any damage and make sure it isnt grounding out. Thats if you blew the inline fuse
You may need to dail your amp gain a bit lower if you blew the amp fuse. I have done this in the past, and it was caused by raw ignorance.
And of course, make sure all of your fuses are the proper ratings of the rating on the amp, and the combined system amperage of your sub amp and upper range amplification.

if i am calculating correctly ...you should run at least 100amp fuse in your power wire to the battery....you say you had it around 3/4 volume.....when you changed the song the bass note on the next track may have been heavy and pulled too much a strain on your fuse ..therefore blowing......how high was the gain set on the amp?
massbass60 on 06/7/2007 19:24:25
the gain is about 1/2 way up and it is 100amp fuse
massbass60 on 06/7/2007 19:26:45
what is the inline fuse? it is the fuse that is in the wire running from the amp to the battery that blew

Again, on the amp or the fuse holder? Do you have a two or four channel for your speakers??
massbass60 on 06/7/2007 19:28:43
i have a one channel. Is fuse holder the one thats spliced into the wire? cause thats the one
ShootuhMcBustaCap on 06/7/2007 19:36:29
Ok, I think trunk may be on the right path here. What is the rating of the combined fuses of the amp? Again, first thing I would check is the run of the wires and the ratings. If a fuse blows, its always for a good reason, and your gain and volume sound about fair to be ok with a hundred amp fuse.
So we do have established that there is only one power amp currently installed in the vehicle?
massbass60 on 06/7/2007 19:38:56
i have a kicker kx1200.1 for my subs and punch 200.2 for my mids and highs
100amp for my kx1200
40amp for my punch

and these amps have their own seperate power cable?? and what is the fuze value on each amp......not the fuze spliced into the power cable...but the actual fuses on the amps....take the number on each fuse on the amp and multiply that by how many fuses you have on that particular amp....if it exceeds 100 amps..then theres a pretty good chance that you need electrical upgrades....starting with the inline fuze.
massbass60 on 06/8/2007 00:03:02
both amps have their own seperate power cable. not sure of how many and what size fuse is on it. will check tomm. but would it help to know that it has been playing fine for about 2 weeks then today i had it cranked pretty loud and changed the song and thats when it blew
trunkisloud on 06/8/2007 00:29:39
thats whats leading me to believe your fuse value on your amp is larger than the fuse in your power wire....when you push it hard ..thats when it really draws the current....you can play at low to mid volume just fine...but as you get louder it draws more amps and causes the weakest link in the system to fail....that being the fuse....it is a failsafe to protect the components in your electrical system....too much draw on your electrical can cause damage..maybe not immediately but eventually you will have issues..thats where the big 3 upgrade comes into play..but we can discuss that after you correct the problem at hand.

If the main power line fuse at the battery blew out and only on the 1200.1 Kicker amp, this sounds like a large power surge hit the amp. Sometimes it's a simple problem like a weak fuse and it just went kaput.
The other reason this fuse blows, is when a surge current from the amp exceeds the fuse value for a few seconds or more. Changing tracks and having the amp gains set too high can cause this fuse to trip out too.
Try dialing back on your 1200.1 amp gain and use minimal bass boost as well. In most cases, that should correct the problem. Have a spare fuse or 2 on hand too. If this happens again at normal- loud bass levels, your amp may need some bench testing as it may have some internal circuit damage and is drawing too much current.

ok I changed the fuse today everything is fine so far got a few extra fuses too.
i went and checked where the place that installed all the stuff grounded the amp and it wasn't on bare metal it was painted. I got all the paint off and its now on bare metal. i don't know if that may have something to do with it or not.
swez on 06/8/2007 20:44:40
It cannot hurt and only help gain a better return feed line to your electricals. If you have a little grease on hand, coat the bare metal to prevent rust later.

A nice, paint free ground is always good. I think this kind of sounds like a fluke, hopefully that is the case.

Everything working out for you massbass??
massbass60 on 06/10/2007 17:40:02
yep so far everything is back up and running(bumping)
