why do i need an amp if i'm getting subwoofers?

@Brian D- not at all true or accurate response. However. the rest of the responses to the question here are factual, supporting that a power source is needed to drive a subwoofer and even most woofer/ midrange drivers of any respectable size and output.

I am running a infinity 1264 reference at 300 rms 1 cu ft sealed enclosure for a year now , hits hard and true .... dont listen to haters who spend $$$$$$ lol

will this work with a single 10" Boss Phantom?

Question; Why wont my 1,100 watt peak mono amp drive my 3,500 watt speakers..(2x3500)=7,000Peak=3500 Rms/ 1100 watt peak mono amp = 550 Rms. SPEAKERS NEED 7 times the power youre giving them. Go with lower wattage speakers, 600Rms watt max and 1100 peak = 550Rms amp = 1100 peak watts= 550 RMS....Real world numbers are more like 275-325 RMS from the amplifier. Same with speakers. 3500 peak = 1750 RMS/2=875-925 RMS.... Either way if you underpower your speakers ,or overload your amp Its not going to work correctly. Dont forget ,it's a SYSTEM. Everything must be compatible and work together to make the System a success. Your 1100 watt mono block ,in reality ,will pump around 275-325 into a single sub, comfortably... Therefore you'd be better off getting a 1000 watt peak power handling Single voice coil sub. That's 200-350 W.RMS max . Allowing for decreased amp output to around 3/4 below max gain to avoid audio clipping and eliminating the chance of possible distortion and ultimately, speaker failure. You'll want a speaker with a sensitivity rating of 88 or higher. 1w/1m is how its measured. 1w tone at 1 meter away = 88db of volume.(Higher is better 93-94 is ideal . This means it takes less power to generate sound. Your amp will not have to struggle and will perform flawlessly at lower ,as well as higher volume levels. Amp output and speaker input should be matched as closely as possible with the amp gain at 3/4 below max gain . Most mono blocks have a remote gain control. You'll use that to fine tune the bass after initially tuning the amp to 75% gain, and connecting all speakers, The goal is to find the "sweet spot" where you hear all speakers equally. Incorporating carefully tuned ports and a series of baffles to maximize sound output using the enclosure its self to acoustically amplify the sound and to project that sound at precisely the same moment as the identical sound is projected from the front of the speaker system, Offers an incredibly wide sound stage virtually surrounding the listener in 360 degree full range sound , like you were right there!. At any volume level.. Here's how we design our systems. To get the widest frequency range possible on the sub bass spectrum, (~20- ~100 Hz, We use an accoustically tuned subwoofer enclosure. Custom built in house. (Think acoustic guitar, cello, violin, brass instruments ,even drums ,all resonate internally, meaning the sound is produced , then amplified natrualy inside the "box." Our enclosure, with added mid bass driver and seperately ported, even reaches the higher "Speech" and "stringed instrument range of ~80~700Hz " The Bass port is tuned to frequency down to the 'Fs' (resonant frequency) of the driver. Creating a slow dropoff down to8 hz below Fs. up to ~90hz! Our System utilizes much lower amplifier wattage requirement due to the enhancement of otherwise unused sound, accousticaly disbursed and exiting to the rear of the driver. Our design channels the rear sound from the driver through a tuned series of ports to amplify and deepen the tone of the accoustic waves that would otherwise be lost or heard as distortion or other unwanted resonances. With mid range drivers covering the spectrum between ~90Hz and ~700-~1KHz. And the use of high quality pizeo tweeters , for higher frequencies, around 1K to 15-18Khz (Tweeters are independently adjustable with dedicated Fender Original volume controls.) effectively covering the 20Hz to 20Khz "RANGE OF HUMAN HEARING". A pair of small satttelite speakers add even more to the sound stage with the ability to be positioned on either side of the main unit(s). 4" full range drivers also ported, and tuned to~=/-500Hz to 800Hz as well as 3" midrange drivers to reinforce the mid ~700-15Khz range .

will this work a two Rockford Fosgate Prime R1S412 R1 12-Inch 150 Watt Subwoofer - 4 Ohm

Yes,and i wouldnt worry about too much about overpowering them either. The RF sub is a 150rms with 300 watts of peak power . this amp says 1100watts peak power at "2ohms" all that means is it can give you that boost in short tiny bursts and from previous issues with boss quality likely not at all. It will probably overheat first and go in protect mode. But since that Rf sub is a 4ohm svc it shouldnt matter really .according to these amps specs its says 413 rms @ 4 ohms , which imo is bologna . i own this amp and max at 4 ohms @14.4v ill say 175rms max. Actually i wouldnt even buy this amp if i were you . but if its too late just dont turn gain all the way up and all other bass settings all the way up itll be fine . .

メリハリのある低音を鳴らしてくれます。

R1100Mからkickerのcomp vx 12インチウーファー（RMS.750W Max.1500W）に接続して使用しています。メリハリのある低音で最高です。パワーの限界を感じないような鳴り方をするので、アンプの余裕を感じます。比較的低価格でパワーのある低音を鳴らせるのでオススメです。

カロのアンプを物色中にたまたまアウトレットで安くなっていたので購入。アルパインのウーファーをキチンと鳴らせている。今の所何も問題はないです。

シンプルに設置しやすいです。

２０年位前のアンプとの交換です。バっ直電源やスピーカーラインはそのまま流用の為短時間で交換できました。 Loパスモードで運用、リモコンで出力調整が出来るので音が作り易くて満足しております。また、思ったよりサイズが大きいですが熱処理等を考えると小さいより良いかもです。

意外と良いよ

90年代のウーハーアンプを使っていましたが年数劣化で電源が入ったり切れたりで、買い替えです。こちらの商品使えます、意外とbossエンブレム LEDライトが光る、音圧は、デジタルに近いかもですツマミ部分が有りマイナスドライバー無しで音圧調整できます。私のウーハーは昔のホームシアターウーハー6Ωで音圧を楽しむ感じで車の中で昔風ホームシアター感満喫してます。ウーハーにより音圧が変わりますので買う人は、自己責任でお願いします。

安い

30cmのボックスウーファーを鳴らすのに使用していますがなんの不足もありません。他のスピーカーと比べてだいぶ抑えめに鳴らしていますがむしろ曲によっては低音しか聴こえなくなります

I purchased the R1100 last week and about half an hour later was emailed to say they did not have it in stock but could send the R1600 for no extra charge. So although i cant speak for the quality of the R1100, i can give a shining review for the R1600. Package arrived earlier than expected and immediately on opening it you could tell it was well made. Its currently hooked up to a single 400w 4ohm sub and it sounds fantastic (RMS of the amp is 350/4ohm). The remote input thingy is also really useful so you're not constantly deafening yourself. Hopefully it's durable enough to last a few years but so far I've been nothing but impressed.
