Help with the 12w7

[jdub486 10+ year member]

I just got a 12w7 and put it in a slot ported box tuned to 32hz. Gross volume is 2.25, net is 1.75. It is fully braced with a double thick front baffle. I am powering it with a Phoenix Gold Xenon 600.1 with a birth sheet that says 816 watts. It does not get as loud as I thought, nor does it sounds as tight as I thought. Is the amp holding it back? If it helps, the car is an e46 BMW 3 series with no trunk pass thru and a very sealed trunk. Let me know if you think more power is key. Factory 120 amp alternator and battery, 0 gauge power wire to d block, 4 gauge to amps.

Luxury cars tend to be harder to get loud because the construction. Does the rear seat fold down? If it does try that. Also, which way is the sub and port facing?

i sent a 10w7 1200rms just fine so i think that 12w7 could use at least 1000rms to get what your looking for. and like was said, luxery cars are harder to get loud.

ya fargof has a good point. try different ways of aiming it in the trunk, too. a bigger amp might help, but not as much as you would think. also, if you can, try different enclosures, bigger, sealed, bandpass, etc. and see what you like best
