Alright I have one DBDrive PL12D4 subwoofer powered by an AmericanPro v.s. 1409 amplifier.

Features of the DB Drive PL12D4 include:

* 3" dia high temperature 4-layer voice coil

* Extreme excursion motor structure & suspension

* Multi-layer treated paper cone

* Layered UV treated foam surround

* Dual spider linear design

* Strontium (SR) magnet with attractive rubber boot design

* Attractive matte black anti-resonance die-cast aluminum basket

* Integrated tinsel leads for high excursion

* Machined push-button terminals

* Rigid dustcap design 12" 1500 watts Dual 4 ohms voice coils

* Sensitivity: 89 dB 180 oz magnet

Features of the AmericanPro VS-1409 include:

* Four Channel Bridgeable Amplifier

* Power Ooutput: 320W x 2CH. = 640W @ 2 Ohm Max.

* 220W x 2CH. = 440W @ 2 OHM

* Bridged(Mono): 640W x 1CH. = 640W @ 4 OHM

* MOSFET DC-DC Switching Power Supply

* Built-In Dual Protection: Short Circuit/High Temperature

* High/Low Adjustable Level Input

* LED Power Status Indicator

The speakers peak power is rated at 1500w(max) and 750w(rms)[375w(rms) per voice coil]. The amp is rated at 2000w(max) and 1000w(rms). I have the amp bridged at 640w(rms) @ 4Ohms but the actual load on the amp is 8Ohms due to the way I have it wired which is in series.

My questions for you guys are: 1. Is there a better way to have the sub wired? 2. Are the amp and speaker a good combination? 3. About how much is that sub worth if I was to sell it?

Thank you all very much in advance for your help!

Here is a pic of the sub...

not much you can do there. a single dual 4 ohm sub will wire into either an 8 ohm load, or a 2 ohm load. You would get more power out of a 2 ohm load, but that amp bridged is only 4 ohm stable, and a 2 ohm load would probably cook it.

so, no, thats not really a good combo. I mean, i guess there's nothing technically wrong with it but a single dual 4 ohm sub paired with an amp that puts out max power at a 4 ohm load isnt the best.

 
so you are sending your sub like 300 watts when it clearly wants 750 a coil.....

thats your problem right there.

you are getting half or less of your 4 ohm rated power at 8 ohms.

Try a AQ 1200 for $250 it makes 1200 at 1 ohm so no problem there.

sell your amp and get some real power on it, you will want to keep it once it gets loud probably.
