Customer Q&A

11 questions already asked

Q
Will a rockford 200x2 channel amp work for a sound ordnance B-12 sub?
ezra808  May 07, 2024
1 answer
A
The Sound Ordnance B-12 Ported subwoofer enclosure is rated to handle 250-watts RMS maximum, Ezra. If you are bridging your 2-channel Rockford Fosgate amp it will most likely overpower the subwoofer's RMS ratings. You can use one channel of your Rockford Fosgate amplifier to deliver 200-watts to the Sound Ordnance subwoofer with great results!

Q
Can I hook a amp up to my factory radio?and if I can what amp would be good?
ronnie  Dec 24, 2023

A
Greetings Ronnie. Thank you for your question. Factory radios do not have preamp outputs, but you can still add amplifiers to them. In some cases the aftermarket amplifier will have speaker level inputs, in cases they do not, you get a converter from speaker level to RCA. You can basically connect any aftermarket amplifier to a factory radio one way or another.

Greetings Henry. Thank you for your question. Im not quite sure what your project is, but this will need to be connected to an amplifier that has 50-250 watts.

Assuming you already have an amp, you'll just need speaker wire. If you don't already have an amp, there's gonna be a lot more to it.
jason  Aug 11, 2021

12-14 gauge Speaker wire, mono amp, 8 gauge amp wiring kit and a RCA cord with a line output converter

Q
How will this sub perform with a 150W RMS amp? I see that you guys recommend a 200W RMS amp. Will I be okay with the 150W? How will the sound quality be? How loud will it get? I'm just looking for deeper sounding bass, and a little more bump.

Q
What amp should I use for this speaker set up?
rick  May 18, 2014
2 answers
A
I was told by crutchfield to match at least 75% of the RMS of a sub a couple years ago. With that said, running the Sound Ordnance M2100 with a bridged connection is what im using, and it works awesome.
