I have a Lightning Audio B2.150.2 amp (450 watt max 2 ch.), and the fuse keeps blowing on the amp. Anybody know what the problem is? I checked all the connections, made sure the fuse in the power wire was fine...replaced the fuse in the amp twice and it blew twice. ?!?!?!
Does it blow as soon as you put power to it, or when you start playing your music, or once as you turn it up? Make sure your power wire isn't grounding out or wires aren't mixed up somewhere. Did you recently do any changes to your system?
ok, i hooked it up, checked the connections(pretty sure i did it right, it was the same as the amp i unhooked)...and as soon as i turned my key to put power to it, you could hear it pop through the speakers(the volume was barely up too), i'd look and the fuse was blown. any ideas??? and no, i didnt change anything, except unhook the other amp to hook this one up(but they're the same amp, just bought for a friend and was testing it).
haha, yea, i pretty much just got it cuz it was cheap. and thats what my friend was looking for, but is there any way to fix it or is it pretty much shot?
Ok, just for clarification (i dont think i said what i was powering), i had the 2 channel L.A. amp, powering two RF T162C's.
The amp is rated for '75 watts x 2 @ 4 ohms. The speakers are rated '75 watts' and are 4 ohm speakers. both products are made by rockford fosgate, (technically) so the ratings should be similar...they're both 75 watts RMS (either per speaker, or per channel) and 4 ohms.
try shipping to them to fix it and see what it costs you, and when you get it back you realized you coulda gotten better for the cost's maybe over 80$ if they even fix it? and just have to accept that you...
i only had two speakers that are 4 ohms each to the amp, 1 per channel. seeing as the amp is 2 ohm stable stereo, i think it's 4 ohm stable stereo too...doubt it, but thanks for the suggestion.
The amp is very likely blown, blown transistors. If you don't want to solder it back together yourself put it on ebay. People buy blown amps, but cheap ones are not worth much of course as they expect to get paid for fixing them. I've been told they are not any worse than audiobahn/bazooka/visonik/etc asian made amps. What you can do is take a DMM (digital meter) set to ohms, and check between the pos and neg speaker leads of each channel and bridged. If you show no or nearly no ohms like if you touch the leads of meter, then it is blown for sure. But it may be blown anyway, you would have to get inside it and measure some things to find what melted. If it blows fuses then something is shorted for sure, it should protect with wrong or shorted speakers...it should. If it blows when you trigger it then it may be the outputs maybe. Any amp that size should fire up on a 7.5A fuse if not playing music really loud. It also might put full voltage to your speakers before the fuse blows, maybe 20-30V so be careful.
?!?!?!
