Kicker KX150.2 amp problem

My system was working fine the other day...after running it at 20 volume (out of 30) for a few minutes, I turned it down momentarily, when I turned it up again my amp/subs weren't working. I checked all of the power and ground lines, as well as speaker leads from deck to amp and from amp to subs...nothing was shorted to ground outside the amp. So I checked the amp...the 25A fuse in the side of the amp was not only blown but melted all to shit. It kept blowing fuses so I took apart the amp and checked over evrything. There are 2 white rectangular things about 1cm by 1cm by 3-4cm...(I think resistors...they say "5W0.2[ohm sign]J")...both of them have some brownish black crusty stuff on the sides of them, but they don't smell burnt. There's also 2 yellow cylindrical things (I'm thinking transistors here...they say "Su'scon 35V 2200uF Kicker Livin Loud [SD] 106*C 0336(V)...the soldering is partially melted on the bottom of the circuit board they're mounted on, but only on one prong of each of the 2. There's also a small resistor I'm not sure's got a teal body with stripes going black, ?, ?, copper...I put the question marks in because I'm not sure what's supposed to be there...the middle is a grayish color with a black band through it...I found a few similar ones with a teal body and stripes going black, brown, orange, copper though...I have an alright knowledge of electronics but I don't really want to start tweaking stuff and risk screwing something out of commission...just hoping to get some advice on what's actually gone wrong and how to fix it...By the way, the main circuit board says "Kicker KX150.2&200.2 025TK1502 Nov.03.2003 Ver.2.1...thanks for anything you guys can help with...

You fried a MOSFET and probably that amp had a bad quality build.

Re: Kicker KX150.2 amp problem

How man ohms are your subwoofers, how many are there and how do you have them hooked up? It sounds like to me, you had too low of a load for the amp to handle. However, the amp should have automatically shut down and gone into thermal protection mode. Since it didn't it, it overheated and turned into jelly. I hope you have a warranty! Before you try to return it, be sure you meter the ohms of the subwoofers, or they won't honor the warranty. Let me know! Be sure to leave feedback or I don't get paid.

Im totally confused n where to put the settings on this amp and i just want some straight forward help please?

Your SX650.1 is 2 ohm stable so wire the voice coils in parallel and the speakers in series, then bridge the amp. Keep your multimeter close. Don't forget to beef up your input wire size to 4 gauge on the positive and the negative side. The rear channel should be set around 80 Hz. Your amp has a variable low pass crossover (30-200 Hz) with adjustable slope (set at 12/18 to start) but you should be able to hear the bang and the boom in the sub woofer. This is only a starting point for the real ear tune. I turn the gains all the way down and give the head unit 3/4 volume, turn the gains up just before it starts to scream then fine tune the frequency (Hz). Do the front and rear separately by disconnecting the RCA's, and then together. Try and play a wide verity of music while your adjusting your amps, but fine tune what you like. I hope this helps to get you started, Ray

I have a kicker ix 500.4 hookd up to polk audio 6x9 and 6.5. if you play the system past about 25 volume the subs will keep playing but the speakers will cut out for a few seconds as if its hiting the

Make sure your frequency is no higher than 80 on the low and 120 on the high. Check speaker polarity with a AA battery(Speaker pops out when polarity is correct) Make sure the speaker crossovers are working properly. Check your ohm load when you connect the speakers together with a multimeter at the amp. Ohms that are too low = heat. See what your amp is rated for. After all that, turn the gain down all the way, turn up the volume to 25-28 and readjust the gains

My amp kx1200.1 works only 5 minutes and then getting real hot somebody have any idea

You need to swap your main battery for a high performance kinetic... and maybe even ad a small kinetic in the back as well (fused separately) and see how that works for you. Just one oversized kinetic battery replacing your stock battery may do that trick. Remember, its best to install two batteries of the same brand and size, its ok to use the same brand and two different sizes (a kinetic 2400 and a kinetic 600 for example, but with an isolator) but its easier and simpler to just put in a kinetic 1200 or something that will replace your stock power sucking ineffecient lead acid stuff.

Jh202 amp works for a few minutes stops for a few minutes any ideas

Sounds like the amp is going into Protection Mode. Does yours have green LED light then RED LED on it? The green is power and the red is Protection. You will need to either change the OHMS wiring or Put A Fan on it to Keep it Cool Inside.
