I feel like theres more potential...

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 a good combo

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.

those subs are cool, that amp is not so much
