Determine the impedance of your sub or subs. This is just what I was looking for! All pioneer to. Unlike multichannel amps, mono amps are really designed with subs in mind.
Answer Upvote. Since amplifiers put out power depending on the load that's attached, you need to make sure that these numbers line up. If so, then this instructable is for you!
Even a small sub often requires upward of 50 watts RMS, which is more than the built-in amplifiers in many head units can put out total. It does free up internal volume in the box, which may help the sub reach lower frequencies.
The easiest way to power a new sub is to just pair it with a properly sized mono amp. In terms of a subwoofer, watts RMS refers to how much power the sub can handle without producing distortion or becoming damaged. Correctly ground the amp!
To put it simply, the lower the Ohms, the higher the power to you sub s. Determine the watts RMS rating of your sub or subs.
Choose subwoofers that can handle the appropriate power output at the selected impedance. The chart provided is a useful reference tool. Also the materials you put in absorb the higher FQ sounds... Share Pin Email.
Stuff takes up space and changes the resonance of the speaker cavity.. It can be confusing to determine the correct wire layout, luckily Rockford Fosgate has a handy tool that can be found here! The question is, can you squeak by with the amp you already have, or do you really need to add a dedicated subwoofer amplifier at the same time you add your sub?

Although if you pack it in tight or use lots of foam the air can't travel through it, and you effectively make the box smaller and tune it higher, boom-boom is what you get not thump-thump. Ever been in an attic for a while with regular fiberglass insulation not blown in?
