[QUOTE="Bobby322, post: 5980432, member: 602365"] Long story short...subs quit working when I had it cranked loud for like 5 seconds. Not sure if the amp went into protect or what...but the subs havent been working. The amp turns on and the power light is lit (not protect light). Everything works except my 2 subs. I took the subs out, looked at them and they appear to be good. I checked the wires and they were all good and I re-did them just in case. I got out my continuity tester, and I tested all the wires (RCA, sub wires, sub to sub voice coils) and they all are connected. I checked the fuses and they both showed that they were good on the tester. The voice coils on the subs look the same as when I got them so I dont think I fried it. When I push down on each sub I dont hear a "scratchy" noise, so no idea what would be the problem on the subs. I just un-hooked everything and put it back together and still get the same result. So im thinking maybe the amp isn't putting out any power, but it still turns on. I tried getting out my DMM but its broken, so im going to get a new one tomorrow. When I test out the subs to check if they aren't screwed up, the DMM should read 2 ohms, right? They are 2x2 ohms. Also, is there a way to test wether or not my amp is putting out power with the dmm? subs - [URL="http://dls.se/en/car/prod.html?produkt=en_138"]http://dls.se/en/car/prod.html?produkt=en_138[/URL] amp - Hifoncis 1606D Any help is appreciated, really dont want to send my truck to the audio shop.
