Why does 1 speaker pound but 2 dont!?!?!?

When you're using 1 sub you are running the amp more efficiently
All this being said. . . I've tried the exact same thing only with a Hifonics Zxi 1006. I had similar results as you. I can say that with my experience Hifonics amps like to be run at their recommended load output. MAKE THAT AMP SEE 1 OHM WITH 2 SUBS AND YOU WILL BE VERY HAPPY!!!!!!!!!!!!!!!//content.invisioncic.com/y282845/emoticons/fro.gif.c695f1f814b01c4ad99fe7f8cccadd29.gif

I have hooked up the 1606 on 3 dvc2ohm subs seeing a final load of 1.34 and it VERY loud.. Even at 2ohms the Brutus should have enough power to make those subs sing.. all i can think of is the "reversing polarity" as mentioned above.. I never knew about using the 9v batt.. good tip

MLSTRASS!!!!!!! YOU ARE A GENIUS!!!!!!!!!!!!!!!!!! I reversed the polarity and the shit pounds like CRAZY!!!! My ears hurt! Kicker must have tabbed the polarity wrong because it is connected right within the box. Thank you guys so much for the help! I am a happy stereo noob now!

THREAD CLOSED!!!!!!!!

Maximum power transfer occurs when your output impedance (load) equals the input resistance of your amplifier. This amp is meant to run a 1 ohm mono load. . .anything else is "up in the air" as far as output numbers. If you run .5 (no no!!) or 2 ohms you're going to be running the amp much less efficiently as it can@ 1ohm.

"Efficiently" is the wrong word. The amp will make more power at a lower impedance, but will actually operate less efficiently. For a given output the amp will draw more current and run hotter at a lower impedance. You also are not trying to match the input resistance of the amp. There is no such spec. The amp has an input impedance which affects the interaction of the HU and amp and is has an output impedance which determines the damping factor, but those are pretty much irrelevant to the discussion. What you are thinking is the min rated load.

To the OP, pretty obvious that it was a phase issue.

Yeah I think I really understand what phase is now lol. I used to think that if they were out of phase then they would still be loud but it would just sound shitty. But apparently if they are out of phase you gets no sound!

Mate is obviousy the amp not given enough power to ur subs,or there is a chance of ur wiring beib 2 small and this causes the amps to cut out. but from experience its ur amp not handlng da power

he already figured the problem out newb.

that was the obvious thing to do before i even opened the thread.

i was going to post before i wrote this that the subs were out of phase, and i was 100% posative you were hooking it up wrong.

lol.

its called troubleshooting my friend.
