HELP with amp - No Sound

[Raman 10+ year member]

Hey guys. I had bought a brand new Hifonics Nemesis 750D sometime in July. I never got around to installing it in my Honda Civic Si 2000. I installed it today and everything went well expect that there is no sound to my subs. Power, ground and remote is all good. There is a green light indicating that the amp is powered on and properly configured. I had the protect light on on my first try at powering the amp because i did not ground the amp properly. But everything is good to go now. The only problem is that there is no sound to my subs. The subs are wired at 1 ohm. I know the subs work because i tested them off my 4 channel amp. Can anyone help me out. The amp has line input and output. Im running a 4 channel amp and the Hifonics. My subs are 2 10s t1 power series wires to 1 ohm. Any help would be greatly appreciated. Thanks in advance.

If you require more information to help me please ask, i really want this to work as it is my first system. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

have you adjusted your gain and bass boost yet? Also the crossover and subsonic filter (if equipped) need to be adjusted properly

There is absolutly no sound coming from the subs. I have put the gain on max, boost on max. Nothing just plain silence from the subs. Its depressing //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Try changing your RCA cables. You may be using a bad set......easy test....just use the one already hooked up to your 4-channel

I've tried that still no luck. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Like what was said before.......are you sure your non-fading (subwoofer) output on the Head Unit is turned on?

i fixed the problem. i was bored so i decided to flip around the rca cables. and i heard a boom. THERES HOPE. i turned the gains up and... all i can say my subs are working fine. Thanks for all your help guys. 1 more question. I have a level dial on my amp. its 9v on the left and 0.2 on the right. i turned it up all the way. Was this a bad thing to do?

Yes. There's nothing I can think up right now that should be "all the way up".

You seriously need to cut that way down. That is your gain knob. Try somewhere between 1/3 to 1/2 turn from the left, then adjust your bass eq knob to somewhere in that same area.
