Question about Kicker KX150.2 Car Audio Amplifier
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 about...it'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.

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.
