my mates cooked his fusion encounter amp that was running his type R 12inch.
ive heard that the amp needs to be a digital class to be able to run it sufficiently?? is this true?
any helps appreciated.
cheers
subs don't need to be running off a class d amp
class d just means the circuitry inside the amp is different. the different circuitry makes them more efficient, so, in high power situations (powering subs) class d make much more power with out drawing as much power from your power supply.
killing an amp is very hard to do unless you have wired something incorrectly. if the voice coils of the sub were wired in parallel then that may have cooked the amp, that depends on what channel's they were running on (bridged or not) and what resistance the coils were.
i think the wiring could of done it then. i think he was running both voice coils off one channel bridged off the amp. running at 4 ohms i wouldnt of thought it would be a problem running it like that???
uh can you repeat that![]()
firstly, is it the dual 2ohm type R or the dual 4 ohm type R
What model amp is it?
you can't bridge one channel, it sounds like the coils were running parallel off one channel
dual 4 ohm. its a 1200 watt 4 channel
Well this is what it sounds like to me,
most 4 channel amps are stable at 2ohm per channel but will only handle 4ohm when bridged. it sounds like the coils were wired parallel, effectively only having a resistance of 2ohm
so the sub wired at 2ohm + bridging the amp for a 2 ohm load = fudged amp![]()
it it would have been able to play quite well but when it was played it for long periods or at extremely levels, the amp would have gotten super hot and died.
it went hard as for about 3 weeks, then died in the hot weather the other daycheers for the explanation ill tell him to wire it up on seperate channels next time
or read the instruction manual hehe....
cheers for the rep![]()
cheers for the help lol your gonna be an amp saver![]()
Sir Psycho... agreed with your comment of the previous posts and was not agruing that.
Did not fully read the post... my apologise..... yes parallel is only 2homs.
Though again if the amp is underpowered that is where you will run into trouble, with it overheating as it is working it guts out. ALPINE do the same thing.

If I had that amp/sub combo I would have bridged the first two channels on the amp and the second pair of channels then connected each seperately to each voice coil (4ohms each coil) so the amp doesn't run under 4ohms. Both coils driving with the same signal running at 4 ohms won't create any problems. But the best bet is a Class D amp if you arent running any mids or tweeters off the amp.
