quick question on my AmP!

Hi I was just wondering why the hell hifonics would make a 1200 watt @ 1 ohm capable amp to not be able to handle 1 ohm with 2 subs?!?!? I learned this AFTER i plugged everything in and now my amp is all screwed up !!! So i was just wondering if someone could tell what is most likely wrong with my amp if i ran two subs off it at 1 ohm when it says it can only handle 2ohm min. with 2 subs.... but 1 ohm with 1 sub.... also if u know what is most likely wrong, could u please give me a price estimate on how much it would cost to repair that problem for my BXi1206D hifonics amp.

-THANK you for listening to my dumbass mistake!!!!

Im guessing that your original sub was a dual 2 and you wired it down to 1 ohm, and then you added another dual 2 and you wired it down to .5, which it cant handle. So either get a new amp that is .5 ohm stable, or your going to have to run the hifonics at 2 ohms, which will give you around 300 wats to each give or take,

well under my message it says i have 2x dual 4ohm subs and i wired the 2 of them down to one ohm... but the manual says it can only handle 2 ohm min with 2 subs but it can handle 1 ohm with one sub which doenst make ne sense to me... but my friend had a good idea... wire the two subs into the same + and - terminals so it would be as if the amp was powering only a single sub but the power was being split equally to each that way i can still get 1200 watts... cuz my subs cant be wired down to 2 ohms... so i have to go up to 4 ohms which would only give me 450 watts:crap: so hopefully this would work and hopefully i wont have to get any thing repaired but i was just wondering wut would have happened to my amp and if it was a cheap fix!

I would recommend you invest in a MM and check your final Ohm ratings!

wire the subs in parallel. when you wire them to the amp you will have only one wire giong to + and one to the -. your amp will have no idea how many subs there are.

Is that a D class mono channel amplfiier? If it has multiple speaker connections on the outside, they are likely tied into the same circuit board trace on the inside of the amp, the extra terminals are just there for your convenience... What you are saying didn't make sense to me, maybe I need to read it a few more times.

If you blew up your amp from running it at 1 ohm, then I would not try to run it at 1 ohm again, it will blow up again. I don't see many amps these days that can actually handle a 1 ohm load without eventually overheating and blowing up. They need to rate these things with duty cycles. You can run it at 1 ohm for 10% duty cycle or something, not just say 1 ohm stable...

I can repair your amp for a reasonable price. Check out my site.

Yeh it shouldnt matter how many subs i believe..as long as final load is 1ohm

yea u would think that but in the owners manual... it said it cant handle 1 ohm with two subs but with 1 sub it can handle it and i wired them in parrelell but i think the damage has already been done so i think im outta luck
