Heres a issue thats boggling my mind, a fried told me to come here and see what you guys think
Im runnin a Hifonics Bxi 1208d amp powering 2 kicker l5 solo baric 8" subs in a sealed enclosure...
I paralell wired them to bring em from a 4 ohm down to 1ohm ...
The amp will produce 1200 watts under this...
Now i Wired everything correctly, i even had a few freinds come over and double check everything i did and for a noob at this, they said i did a better job then most pros...
4 guage to a 100 amp fuse from battery to a d-block which splits off to another amp i have for my interior speakers...
The d-block for my ground ...
I have a alpine 1da x200 HU....
well the interior speakers are awesome, they sounds crisp, but im notgetting any sound comming form the box whatsoever, the safty light isnt on, soo that crosses that out
My friend took the box outta my car and put it in his , and the speakers hit like hardcore, soo its not that...
I also hoooked up the amp with the rcas that are powering my interior speakers and still nothing, which makes me believe its the amp...
If anybody at all has any ideas on this please let me know asap, before i have to send this thing back or out to a shop
Thanks In Advance

Did you notice that the speaker terminals of the amp are not the conventional + - + -?

Some of their amps are + + - - If you do not catch it and connect + - + - each speaker is connected either to the positive or the negative wires. Have you tried popping the speakers with a 9 Volt battery to see if they pop? If they do not pop, disconnect one of the voice coils and see if that woofer pops now. If it pops with only one coil connected, the voice coils were wired out of phase.

We just took out the box and hooked it up to my friends amp, and they hit nice....
Were thinking maybe the outputs on the amp are bad???????
Its a brand new amp, And honestly its not a good first impression from that company

Im sure you have. But make sure the RCA's are plugged into the line in not out. If thats not the problem. i am an idiot is the man for you because its an amp issue if its lighting up correctly, you have tested the speakes, changed out RCA's to known working ones and made sure you are using the correct + - outputs of the amp. -------------

HIFONICS IS ONE OF THE BEST KNOW AMPS OUT THERE, GET SOUND AND THEY ARE THE POWER OF THE GODS. TRUE POWER THERE. I AS A OWNER OF THE BXI1206D THE BXI1208D REPLACED MINE. I HAVE NO PROBLEMS WITH MINE NOT ONCE. MAKE SURE THE RCAS ARE CHECKED, THE (+)+(-)- ARE GOOD, MAKE SURE THAT YOU HAVE IT AT 1 OHM. THAT MEANS YOU HAVE TO HAVE 2DVC 4OHMS. DO THIS FOR A TEST HOOK UP A NORMAL SPEAKER AND SEE IF IT WORKS WITH THAT ONE. IF NOT IT IS YOUR AMP OR YOU RADIO.

"HIFONICS IS ONE OF THE BEST KNOW AMPS OUT THERE, GET SOUND AND THEY ARE THE POWER OF THE GODS. TRUE POWER THERE."
When Maxxsonics bought the Hifonics name, the products fell to the ground. I would not recommend the current HiFonics brand. True Power There? that would be a No. From my experience the numbers are very inflated. High failure rate.
"Power from the Gods" came from the Steve Mantz designed, ZED built amps. Series 6,7,8 and the Gen X stuff, these were worthy of the HiFonics name.

I never had any problems with the Hifonics and that is what he asked right? I been with Hifonics for a long time and I had some many different brands and by far Hifonics is in my top 5. I not here to start anything with anyone but he asked a question and I answered it. Plan and simple.
O yeah the guy that said Something about my Caps. I was having problems with my computer so I did not want to rewrite everything so I left it on there. You have a problem deal with it. Have a great day
