Alpine S-A60M S-Series Class D Mono Amplifier
Product description
Big bass power from a small package Alpine makes it a little easier to get great bass in your vehicle, especially if you drive a compact car. Their S-Series S-A60M mono subwoofer amplifier can deliver up to 600 watts RMS to your sub, guaranteeing some powerful bass on your drive. And Alpine made this amp so small - it's got less than an 8" by 8" footprint and it's just over 2" tall - it can fit almost anywhere. Technology that keeps you on the air Enhanced Shutdown Performance technology rolls back the output a bit when the amp threatens to overheat from playing at its limits too long. Instead of shutting down completely, it continues playing your music, until it cools enough to return to full power. Convenient features A low-pass filter and adjustable bass boost put you in command of the frequencies that reach your subs. The amp includes preamp- and speaker-level inputs, so you can install it in almost any vehicle, even one with a factory radio. If you're using the speaker-level inputs, the amp senses an incoming signal and turns itself on, eliminating the need to run a turn-on wire back to your vehicle's receiver or fuse box. An optional wired remote lets you control bass level from the driver's seat. S-A60M control panel
- 330 watts RMS x 1 at 4 ohms

User questions & answers
| Question: | Will these power 2 10in pioneer subs |
| Answer: | No, only powered outputs |
| Question: | Im usimg this amp on one 8 inch alpine type r. will this be able to handle a 2nd 8 inch? i believe its 300 or 330 rms |
| Answer: | Yes, I have 4 outdoor speakers being powered by the amplifier. The only issue I have found is that if you are going to use the RCA connections, you have to use all 4 RCA connections to get the audio to all 4 speakers. I have been using the Bluetooth option since that will output the audio to all 4 channels. |
| Question: | Will this amp push 1 12" type R good |
| Answer: | I would say no. There is a volumn, treble, and base controls, but no balance control. |
| Question: | Is this amp 600rms @ 2ohms |
| Answer: | It is bridgeable.. if you know what you are doing. If not you will let the magic smoke out |

User questions & answers
| Question: | Is this amp suitable for a custom 10" cargo sub for an 07 Dodge Durango truck, and can it be mounted under a seat |
| Answer: | Yeah it can I have mine mounted under the seat of my 2014 chevy silverado double cab rear seat with 2 10 inch Fosgate subwoofer |
| Question: | Will this amp power "two" alpine swr-12d4 type-r 12" subwoofers with dual 4-ohm at the same time |
| Answer: | This amp is stable at 1 ohm. If you have two DVC subs then wire each 4 ohm coil in parallel, dropping the impedance to 2. Then take the subs and wire them in parallel together for 1 ohm. This process requires great subs like Orions or similar. But I will say from experience as I've done this with 2 12" Orion 2NT subs and the sound pressure would blow your hat off your head and strike the windshield. The power rating from Alpine is tested in the factory@4 ohm and it pulled 660watts RMS. So one ohm will make you think otherwise. |
| Question: | Will this work with either Alpine Type R's, SWR-12D4 and SWR-12D2? Would the 2 ohm pull more power from my battery dimming headlights more |
| Answer: | First of all you will likely need a capacitor to supply enough power to the amp during the peaks. SWR -12D4 wired in parallel will give it a 2 OHM load for the amp to produce 500W rms. That said you need an amp to make 750W rms to take a full advantage of type R 12 woofer. |
| Question: | Hi, Does this come with Remote Bass control Knob |
| Answer: | It doesn't come with it but you can buy it separately. |

User questions & answers
| Question: | Is this as good as a JL audio amplifier |
| Answer: | Never owned a JL Audio but, this Rockford is definitely worth it's weight in gold. |
| Question: | So either where u hook the sub you can get a 1ohm load the two speaker output is not a left and right channel am i correct |
| Answer: | It has 2 negitives and 2 positve out puts just connect 1 pos and 1 neg its gonna be the same ima is. 1 channel amp at 1 ohm |
| Question: | Why does it have 4 speaker outputs do i bridge if only hooking up 1 sub |
| Answer: | It is a mono block, meaning only one channel pos and neg. But it has A and B connections, they DO NOT count as separate channels. It's just to make things easier if you planned on several subwoofers for an install. This amp is stable down to 1ohm and will easily exceed the 750w RMS rating, for instance my birth sheet shows 940w RMS tested before they boxed it up.So be careful when choosing your subs. I run a single Rockford P3D2-12in wired in parallel to 1ohm. Make sure your sub or subs can in total handle more than 1,000W max. If not, you are likely to burn up your voice coils with this little knock out amp. |
| Question: | have a sundown sa-12 d2 will this supply enough power and if so how should it be wired |
| Answer: | Depending on the subs ohm rating. I'll assume it's a two ohm dvc sub. In that case you'll get the complete full power of the 1 ohm amp. Which is 750 watts Assuming the sub is not internally wired, meaning there is two positives and two neg. coming out of the sub, then you would take both positives wired together and both neg. wired together. You would then connect the two positives to the right channel positives on the amp then take the two neg. and connect those two to the left channel neg. on the amp. This would give you the 1 ohm load or full power of the amp. Now if your sub has only one pos. and one neg coming out you would wire it the the same way with the pos wire going to the right pos. on the amp and the neg. going to the left channel neg. on the amp. The amp itself totally rocks out but the manufacture also advises getting a capacitor or cap to help when hitting heavy bass for continuous periods. I ended getting a 1.5 farad digital cap. Which is rated for approx. 1500 watts RMS., more the enough for the 750 watt this amp can produce. Though the cap. Is not required, you'll will def. hear/feel the difference in bass with one. Just a side note, the amp is rated for 750 RMS minimum. Rockford tests the amp before it leaves the factory and assigns a " birth sheet " stating the actual watts that exact amp produced when tested. My amp birth sheet stated my amp can produce 943 watts RMS. Pretty sweet. That rating can only be achieved with the proper wiring. Meaning using 4/6 gage wire and assuming your vehicle can keep the required 14.2 volt Continuously, that's where the cap. comes in. To keep the juice flowing at a continuous 14.2 volts. The cap. Is bought was purchased for about $50. T-Spec V6-1-5DDC Digital Capacitor 1.5 Farad Digital T-Spec V6-1-5DDC Digital Capacitor 1.5 Farad DigitalSold by: Amazon.com LLC Happy thumping! |

CRITICAL EVALUATION OF IN-CAR SOUND
Alpine’s top engineers from all over the world gathered in Alpine headquarters to deeply research and evaluate sound systems from both the aftermarket and high-end OE manufacturers. Many systems today have incredible dynamic range and reach sufficient volume levels, but lacked the reality of instruments and spatial imaging. As a result, Alpine ID was born, a sound philosophy that continues to inspire us to create a new level of sonic performance.
ALPINE: IMAGE DEFINED
Or Alpine ID for short, is the new Alpine global sound culture with an evolutionary approach for solving what’s missing in most car audio systems these days: great spatial imaging and depth of sound stage. It centers on developing matched sound systems with core components that work together to achieve greater realism in the sound stage while maintaining great dynamic range and accuracy.
