What are my options...?

by Undeclared Nov 3, 2008 2:16PM PST

I have two 12in Momos already pre-fabricated in a box, but im not sure how to power them. My main question is about what amp to choose. I would like some options to pick from. Dependable quality as well as the best bang for my buck is what i'm looking for. Any advice would help, thank you-

The most important part of powering subwoofers is choosing the right amp for the job. This isn't a one size fits all sort of deal. You'd need to know the model number of the speakers, so that you can find out their power handling capacity, resistance, and number of voice coils per speaker. Too much power and you blow the speaker. Too little and you risk damaging the amp. Improper wiring can kill both.

Get back to me with the exact model (eg. Polk/Momo MM2124, MM2124DVC, etc.) and we'll crunch the numbers to find the best setup. You should be able to find the model number on the bottom of the magnet on the back of the sub.

Google the model number

The Polk/Momo site's specs state that your subs are rated for 720 continuous watts or 1500 watts max at 2-ohms. All you have to do is find a single channel amp that pushes up to (but not exceeding) that power level at that impedance. Pay close attention to the impedance on the amp when choosing. If the amp is listed at 4-ohms, you'll need to multiply that number x2 to account for the difference in resistance.

The Pioneer GM-D8400M is a good fit because its continuous and max power ratings fit within you sub's range. It's a mono amp, so it won't require any channel bridging, and it's $300 price makes it a good bargain.

There are dozens of good mono amps that fall within the 2-ohm, 700W continuous, 1500W max range and you can usually find that prices are well below the MSRP. Happy hunting.
