So here I go again. To recap here is what we are working with:

-Alpine 9883
-Alpine MRP-F250, driving eD 6000s v.2 comps
-Alpine MRP-M500, driving a JL 10W0v2 (single 4 Ohm) (specs here: JL Audio: W0v2 Subwoofers)
-Box is sealed at .65
-Rockford amp install kit for 1000w amp. Monster RCA's, monster speaker cable, good ground, etc.

The M500 and JL are new, they replaced a JBL 150.1 and a eD SQ10 sub.

I totally expected quite a change in bass output, but I get VERY little. When I turn up the Subwoofer at the head unit to 10 or so, I get plenty. The gain is currently set just past Nom.

My concern is, should raising the sub output at the HU be necessary? My first thought is that I should get fair bass from the HU sub set to factory default and the gain set to Nom.

This is bumming me out. I may be missing needed info for a diagnosis, but being the green horn I am I don't know what to ask.

Thanks in advance.

Raising the sub output at the HU, you will be fine,all it does is raise the RCA line level. play it at you happy volume and back off as nescary, i suggest you do this with many diffrent songs.

Is the old sub and new sub about the same sensitivity?

Did you build or buy a custom box or throw it in a pre-fab?

Why would you expect a lot?

The specs are nowhere near each other, but **** what do I know?

Built a box to specs from JL

I guess I was expect alot considering I doubled my amp output wattage.

when you turn up the subwoofer volume on the HU and the volume on the HU all the way up, does the speaker clip or sound like it's near death ??

Just beacue you got all new Equ. and you leave it all on defaults does not mean it will sound great , you have to tweak it.

If it's DVC, do you have it wire right for your amp ??

I.E. Do u have you sub wired at like 2 ohm's, But your amp only does 4ohm's ?

No, I can turn the volume up until your ears bleed and it holds up well.

The sub is a single 4 Ohm.

I have been tweaking in fact...

I found the "Bass Center Frequency" settings and have been fooling with those. I have no idea what I'm doing but I'll tune until I figure it out.

Part of my problem is the wide genre of music I listen to. And I realize that not all music will sound good when set to play another particular type.

not trying to change the subject, but how do you like that sub?

Which should yield a 3 dB increase in output - audible but not overwhelming and no where near double.
To what Rudeboy says, that +3db is roughly equivalent to 1-2 clicks of a volume knob or if your volume knob doesn't have those audible or tactile detents just barely turning up your volume knob.
