OMG whats wrong with my setup!?!?!?!?!?!?!?

[mkiv]

HELP, my subwoofer was barely moving, so i bought a sundown sd 2 10 2ohm, and a new precision power bk650.1d. It is still barely moving at all. So i tried to connect my amp to my iphone instead using an rca to 3.5mm adapter, and it was hitting hard. So what exactly is the problem on my setup, the headunit is a pioneer avh p4100dvd which is only 3 years old and the subwoofer outputs have never been used, and it cant be the rcas because i just replaced them with kicker brand rca.

HEEEEEELLLLP

THANKS!

Subwoofer setting off or very low.

On your head unit, turn the bass boost to 0, put the subwoofer level to plus 5 or 6, check the phase on the head unit. Oh and make sure the subwoofer out is on. Set the crossover.

Its 4 volt fellas, that hu has a LOT of settings for sub out. Also the sub level goes from -24 (.01) to +6 (4.0) which is completely seperate from bass boost. Sub level controls the output voltage. Hope this helps

 

[basswiigee]

sub level +6

DVC coils wired out of phase

The subwoofer is set to on and the level is on 6, bass boost on 0, eq on flat. I only get a decent response if bass boost is on and eq is set to Superbass, I am really confused. Helllp it's been like a month now.

THANKS

Is your sub wired to the amp *exactly* like this:

Also - have you:

1) Made sure the subwoofer output is ENABLED in the pioneer headunit menu?

2) Set the subwoofer output level higher in the pioneer headunit menu?

3) Tried changing the subwoofer PHASE from normal to reverse or vice-versa on the pioneer headunit menu?

4) Tried setting the subwoofer crossover cutoff frequency higher in the pioneer headunit menu?

5) Tried increasing bass boost on the pioneer headunit menu?

6) replace the RCA cables from the back of the pioneer headunit to the sub amp?

7) tried grounding the RCA rings to the pioneer headunit chassis with a piece of wire to see if the internal pico fuse blew?

Yes, It's wired exactly like that, I used the sonicelectronix video tutorial on youtube

OK, what about the other 7 questions I asked under the picture?

when did the issue start? since you changed the rca cables? go back and check all your wiring and connections (back of the headunit)

Could be a bad HeadUnit. If it works directly from the phone but not from your Headunit after you've properly set the settings then it's your headunit.
