Basic Amp Question?

Question

You guys are good at this, so I'm going to go ahead and ask.

Here's the sub setup I want to get. Nothing big or powerful, just looking for some good sound. Two of these in a box

Audiobahn AW1051T

10" Dual 4 ohms Natural Sound Subwoofer (AW 1051T)

Dual Voice Coil: Yes

Impedance: Dual 4 ohms

RMS Power Handling: 300 watts

Peak Power Handling: 600 watts

Woofer Surround: Foam

Woofer Composition: Paper

Sealed Box Volume: 0.75 - 2.0 cubic feet

Ported Box Volume: 0.65 - 2.4 cubic feet

Sensitivity: 91 dB

Frequency Response: 28 - 1k Hz

What kind of Amp should I look for to power these? I just want to get one amp to power the both of them.

I heard I should look for something around 800 watt output or something. I had a good audiobahn amp and I like the brand. I just don't know the difference in channels, mono, ohms, etc. I'm not looking for a competition system or anything.

Thanks

Answer 1

You defiantly wouldn't need anything too big.

If you want to stay with the same brand, i would suggest the one in the link. It will be slightly under powered but it will still bump and sound decent, not like a competition system.

With DVC speakers,  you can run both speakers' voice coils in parallel (both + terminals to the + wire, both - terminals to the - wire), to make the two speakers effectively 2-ohm loads.  If they handle 300W, you can probably drive them with a 300W-per-channel amp if you're careful not to overdrive the amp.  Most amplifiers will increase their power output per channel by 50-80% into 2-ohm loads, so with this 300W/ch amp, you may get around 450W to 500W peak power into each speaker.

Whichever amp you choose to get, make sure it's stable into 2-ohm loads, and make more sure that it gets plenty of air around it (or it's fan-cooled) to stay cool.  Lower-impedance loads put more strain on the amp.

If you build a ported speaker enclosure,  you'll also want to make sure the crossover (or the amp itself) rolls off the subsonic frequencies.  Also known as a "subsonic filter", it keeps frequencies under 15-20hz from over-driving the subs.  Subwoofers in ported enclosures are very sensitive to over-excursion and inefficient at frequencies under 20Hz.
