Upgrade Suggestions please: new amp or subs?

[epix 10+ year member]

Ok for the longest while I have been using 2 Adire Tempest 15" subs in a custom ported 8.0CU box (I think tuned to 32Hz)

The subwoofers are 8 ohm Dual Voice Coils

Anyways I have had the subs connected to a Boss 3000D sub with the following specs:

Max power, 2 ohm - 2200w x 1

Max power, 1 ohm - 3000w x 1

RMS power, 4 ohm - 1200w x 1

RMS power, 2 ohm - 1700w x 1

and right now I have it on a Lightning Audio Strike S4.600 (rockford fosgate parts) with the specs:

450x1@4 ohm bridged -

I have the subs wired together so that the total impedence is 2 ohm.

What I want is more bass, for some reason this setup isnt putting out as much as other people with just 1 12" sub and amp in a smaller box.

I don't know what the problem is. Would a bigger/better amp make this any louder; what would be a good amp for this setup? or is using these 8ohm DVC subs outdated? should I go with 2x 12" 4ohm DVC subs instead?

Thanks

Considering one amp is grossly overrated (the Boss) and one doesn't push enough power to properly move the Tempests, I'd sugguest a new amplifier. IMO a JBL BP1200.1 or PG Tantrum 1200.1 would work, pushing a real 1200 wrms at 2 ohm.

Also, if you haven't, add some bracing to the enclosure. A box that big will probably flex like crazy under loud volume.

Those are awesome woofers btw.

My last sub was a Tempest in 4^3 @28Hz and it got pretty loud and sounded VERY good. Was pushing an honest 500watts to it.

As mentioned, get a BETTER amp, someting around 800-1000@2ohm would do you nice. The Tempests don't require a lot of power to sound good/get loud, so don't go crazy.

I also run 4 of them ported in my HT, love them old school budget subs!!!
