If we talk in technical terms 1-ohm impedance will hit harder than 4 ohms to create more output when given with similar wattage, just because of the low impedance.
Just make sure your 15" subs have a rms rating of 1000 watts. because under powering your subs is worse than overpowering them. And GUH. see less Yes, it will push two 15's easily.
Generally you should pick an amplifier that can deliver power equal to twice the speaker's program/continuous power rating. This means that a speaker with a “nominal impedance†of 8 ohms and a program rating of 350 watts will require an amplifier that can produce 700 watts into an 8 ohm load.
The very best amplifier for a subwoofer is a class AB or Class H amplifier. Class D amplifiers are too slow and cannot keep up with repetitive bass. A class AB has a toroidal transformer and coke can capacitors so when the kick drum kicks the woofer responds instantly. Buy the power amp that matches the subwoofer.
In this case, about 1000 watts RMS, SSL's website rates it at 1250 RMS.
The Comp 10-Inch Subwoofer works best with a sealed or ported enclosure and 150 watts of recommended power. See below for more details.
The L7R 10-Inch Subwoofer works best with 500 watts of recommended power in a sealed or ported enclosure. See below for more details. *Assumes typical music program with minimal amplifier clipping; varies with enclosure size. See your KICKER dealer for details.
A good rule of thumb is to add at least 2 to 3 inches to the size of the subwoofer. For example, a 10-inch sub should have a front panel at least 12 to 13 inches square. Size the depth of the box to create the volume you require for your box.
Many factors are affecting the weight of the sub-woofers. Size and power are just two of them. So, if you want to listen to loud and deep bass, your sub-woofer must have adequate size.
| Type | Weight Range (lb) |
|---|
| 8″ | 5 – 11 |
| 10″ | 6 – 31 |
| 12″ | 10 – 50 |
| 15″ | 12 – 40 |
The Kicker CompR subwoofers offer hard-hitting bass that is accurate and designed for sound quality. If you are looking for hard-hitting, accurate bass, the Kicker CompR subwoofer is a great choice because the CompR has enough power handling to get you the output you expect from a "Step-up" subwoofer.
Subwoofers. KICKER® 2016 Comp Subwoofers are all about that KICKER bass! On The Edge. A ribbed, UV-treated surround with white double stitching binds the suspension to a thick polypropylene cone for excellent reliability.
Enclosures should be built with very dense and heavy wood. We recommend MDF (medium density fiberboard) or Medite (high density fiberboard), They are rigid, heavy and not porous like some particle boards. We recommend 3/4" (19mm) MDF although 1/2" (12.5mm) MDF is acceptable for woofers 8" and smaller.
if an amp is designed to be 1 ohm stable, then its ok. running an amp not designed to do it can/will end up bad.
For multiple subs, multiply the number of subs by their RMS ratings for a total RMS rating. The amp you choose will have to be capable of powering 75% to 150% of the total RMS rating for the entire subwoofer system.
Overview. 2 Ohm Subwoofers will produce more sound output on less wattage than 4-ohm subwoofers. This makes 2 Ohm systems less expensive and best for most consumers. 4 Ohm Subwoofers will be more expensive but will produce a better overall sound quality.
For example, a 15†subwoofer will not only handle more power than that of a 12†woofer, but it will also require more air space as well. Mixing those two subs together will make your box “out of tune†in a sense. The two subwoofers would be operating together in the same air space although they would run differently.
RMS power handling of a 55 series 12†dual 2 ohm voice coil subwoofer is 400 watts. Two of these subwoofers would mean you need 800 watts of power at to the total circuit impedance.
While series wiring of multiple subs increases the total effective impedance, parallel wiring of multiple loads lowers the total effective impedance. With subwoofers rated at equal impedances, the system impedance is equal to the impedance of one sub voice coil divided by the number of subs.
Sample Amplifier Power Rating Chart:
| # of Speakers | Each Speaker Rating (RMS) | Total Speaker Rating (RMS) |
|---|
| 1 | 100 watts | 100 watts |
| 2 | 100 watts | 200 watts |
| 3 | 100 watts | 300 watts |
| 4 | 100 watts | 400 watts |
Basically, a 2 ohm subwoofer demands less power from the amp and tends to deliver louder bass. On the contrary, a 4 ohm subwoofer will demand more power from the amp and deliver less loud but higher quality bass. Thus, make your choice depending on the kind of bass you want.
