    Ok i have a Kenwood KAC-849 Amp and it just started blinking....I pretty sure its and indication of "Protection Mode" but ive looked at every wire and cable....ive even cut off the ends of all the cables and redid them to the amp but still no go just the blue blinking light....checked the Fuses (1) Amp 40a still good (2) Power cable Amp 30a Still good......I think i need to relocate the ground cable but i didnt have any socket wrenches available (at work) to unscrew the back seat bolt (where the ground cable is grounded to the car) but the amp worked before so im not sure if i even need to relocate the ground cable.....but get this when i was redoing my trunk i unplugged everything from the amp but the ground cable (last one to undo) and the power cable touched the amp and sparked and lil bit of smoke came from the wire not the amp.....So i knew at that point the fuse for the power cable was done for and it was so i bought more 30a fuses and plugged everything back in but no go The blue led just blinks......So im not sure if "I" messed up the amp by allowing the power cable to touch the amp.....

    ALSO::::: The Amps 40a fuse when i was trying to take it out of the amp i accidentally broke the top plastic tip of the Fuse but it still seems to be working.....The part im talking about is where the fuse says 40 that lil bit of plastic broke off.

    Checked all fuses
    Redid all the cables
    Checked every wire even took out the head unit to reassure everything was plugged in

    Any insights? Im going to test the amp in a buddies car to see if its the amp ( $150 :x amp :( ) and if it is then its time to shop around again.....

    if that dosen't work....how many subs are you pushing?? if you have two 4ohm subs, when you wire them in parralell...it drops to 2ohms. that amp may not be 2ohm stable. i have a kenwood kdc series amp and had the same problem. i had them bridged on the amp and run in parralell...so i just rewired them for right and left channel.

    yeah, i hate that parts stores don't stay open later anymore. we had an o'reileys that was open 24-7 until about a year ago...and walmart is just the anti-christ. lol

    UPDATE:

    So i managed to get the fuses i needed. Before i even attempted to do anything I again Redid all the cables and moved the ground cable to another bolt...The amp gets power but still no go just continues to blink

    So
    1)Either its a dead amp :(
    or
    2)I can still test it on another car

    But im pretty sure its dead!

    So any LT Members selling an amp?

    What did the pink panther say when he blew up his amplifier?

    "dead-amp, DEAD-amp, dead-amp, dead-AMP, dead-amp, dead-amp, dead-aaaaaaaammmmmmp, amp!"

    sorry for being a smart ass, lol, but yeah... your baby is fried. seen it happen before. it's nothing like as bad as i did... i hooked up an amp i had to an electrical test panel while i was on my ship. we used it for a good 4 months pushing someones speaker and had it all hooked up to a vcr watching movies with BIG SOUND. haha. well i walked in one day and wasn't paying attention and didn't realize someone had cranked the rheostat up to 400 volts dc before i fliped the switch on. "saw some smoke" was an understatement, haha.

    But ya, i have an old amp stashed around here somewhere i think you could get some descent usage out of. just need to dig it out of one of these closets. it'll get you by till you can find a better one. not that it's bad. i'm just not sure if it will fill your power needs. but either way i'll let it go cheap ;)

    I only had a amp hooked up to a sub or vice versa no other speakers were....I have a high/Low Converter since i have a stock HU but its still checks out and all wires including the remote wire are all still intact....
