Im having a problem. I have a 12" alpine type r dvc 4OHM sub. I had it hooked up to this lightining audio amp. Its a 2 channel amp. B4.250.2 is the model. I hooked it up yesterday and seemed to work fine. Well i was on my way home today and amp went into protect mode. So i figured the amp fried well i have an old MTX sub laying around and it works fine not sending the amp into protect mode. My question is wich is messed up my amp or my Type R.
I know this amp isnt even close to strong enough for this sub, but i just wanted my 12" in there instead of that ratty ass 10" MTX. Any help would be great.

 

since the amp isn't matched to the sub, chances are as your under pushing your sub your actually overworking the amplifier, causing major heat on the components.

better to go with too much power capability than too little.

 

So why did it work yesterday than it didn't today

 

Well if your running the 12 as a 2 ohm load onto a 2 channel and bridging it then that amp may not like that load. is the mtx a d4 sub as well?

my first thought is the mtx is an S4 sub and the amp isnt having any problem bridged at 4ohms. But it might be having an issue bridged at 2ohms.

But just a thought.

 

Its been so long since I had the mtx out of that box I have no idea what it is. As long as my sub isn't fried. I don't care about the amp.

 

get a 9v battery and touch it to the pos and neg and see if the sub moves. if it doesnt then its fucked

 

Does it matter which voice coil

 

nope do em both to be safe

 

jj we need to test my system pretty soon should be done tomm i hope

 

lol ok... test as in? see how loud it gets on the meter?

 

yea don u have one at work?
