A little I.C.E question

[Danny]

Alright all i really want to know what my amp is putting through my subs. (rms) is there an easy way to test this at all. i shoudlnt think it could be puttin more then 100-125rms each sub, through them but i dont know and it sounds great when i can turn the amp up (very rarely due to it cutting out) is there a way can find out cheers Danny

Not sure how you can really test the true output, but generally when cutting out occurs, it's the subs/speakers or whatever that's usually asking for more power than the amp can produce. I.e. the amp isn't powerful enough or similarly matched to the speakers power handling. This is only in my experience - but have seen it many times

Mind you, u can probably work out the output from ohms law or something

 

[Danny]

well its the amp that actually cuts out. when its turned up full i should think they are def not underpowered, it does sound really good. but i have to keep it low because when it hits a certain volume and a low note it just cuts out and the amp goes onto protect. could it be getting to much current i had a 40 amp fuse in the holder in the bay a few weeks ago and that went only1 i had lying around was a or 80. cheers danny

Yup, the amp's what i mean! Does sound good for abit untill it hits the power sapping lows (which i love!)
Literally have seen it happen about 4-5 seperate occasions - including my own mini-system when i first had it.
The subs can simply handle more than the amp can give it. And i think i'd be right by saying if you simply turned the headunit off, then on again, the whole thing starts to work!
It's not a big problem, just means one day when you can afford it, get a bigger amp! I currently am using one that is a bitt too powerful for my subs, but on turning down the gain, everything is fine. At least i know i won't be stressing the amp too much and then it's least likely to blow.
Hope this is roughly useful at least!

Re: Untitled

upgrade ur cabling, get a good earth, and get a power cap.... thats wat i would do so when it hits the big beat it will zap the power from the cap and ur amp might be ok.... but if the amp is really under power it can just blow the fuse on the amp...

Re: Untitled

alright then cheers for that boys. what about the fact i could go all the way before. i have all really good cabling already and a cap but thats simply for show as i know they dont do **** anyway.

Re: Untitled

Only time i have treully experienced the value of a Cap is when i've recently been using my monster amp. Prior to me hooking up the cap, the voltage reading was all over the place - especially when basslines kicked in (the amp has a voltage display on it, as does my cap). However, when i used the cap, the voltage during big bass drops didn't change a bit! So yes, caps are useful - and none more so when you have big ice!
Pretty sure you'll find the subs are straining your amp very badly - and maybe soon enough, to its death. Seen many amps blown because they are being over-stretched. If possible in the future, always go for subs/amps of a very similar power rating. It's a sure way to know it'll be a nicely suited system!
