Boss Audio Systems R1100M-P Monoblock Car Amplifier - 1100 High Output, 2-8 Ohm Stable, Low/High Level Inputs, Low Pass Crossover, MOSFET Power Supply

Components installed: - One Rockford Fosgate R2S-1X10 10-inch shallow loaded enclosure - Kenwood KDC-BT555U receiver/head - Boss R1100M monoblock amp - Sirius/XM SXV-200v1 tuner - Metra single DIN faceplate kit - Metra wiring harness adapter I wanted to use a local business for this installation, but they quoted me $750 to install $250 worth of components. So I decided to order the stuff from Amazon and do it myself. I got a much better head, a better amp, the Sirius/XM tuner (not included in the quote from the local vendor) and the same subwoofer/enclosure for less than $350. It took me parts of three days to do the install, but it was fun, I learned a lot, and I do quality work (even if I do say so myself). The bottom line is, the system sounds awesome. I had already upgraded the stock Infinity speakers in the front and rear doors with a set of Boston Acoustic speakers. I did this a few years ago when the stock speakers got wet or rotted and started buzzing. This gave me a tinny sound that had very little low end. That and the fact that I could not use my iPhone with this system finally prompted me to upgrade. I had never installed an amp before and didn't have the first idea what would be required. Luckily a lot of info is available on the Internet that makes this stuff doable. The local installer had told me that this size subwoofer enclosure would fit behind the smaller driver-side rear seat in my Dakota Quad Cab, but that turned out to be incorrect. The alternative is to spend an additional $200-$300 to purchase a molded enclosure, plus the cost of the actual subwoofer. So I decided to locate the enclosure on the rear floorboard, snugged up against the middle console, facing backwards. I am still in the process of trying to decide how to anchor it there--it's dangerous to have something that heavy not properly anchored down, as it could become the source of severe head trauma in a crash. I am thinking I'll probably use some combination of velcro and home-made brackets. The one thing I have noticed is that, if it is placed directly against the back of the console, the console will not lift up and out of the way in the front seat. This is a problem for me, because that's usually where I place my Glock when I'm transporting it but want to keep it out of view.. But, from a rear-seat occupant perspective, this configuration allows two people to still ride comfortably in the back, though it does extend slightly into each occupant's knee space. It pretty much makes the middle seat unusable though, so if you need that much passenger room, you will need to spring for the molded enclosures that fits under that seat. Luckily I rarely have passengers riding in the back. The hardest thing about the install was running the 8-guage power supply from the battery through the firewall into the pax compartment. Using Internet research, I located the wiring harness grommet on the driver's side, and was able to use a coathanger to get the wire through. I pushed the coathanger through and then electrical-taped the 8-guage power supply wire to the other end of the coathanger. First time it came loose, but second attempt worked like a charm. The wiring harness kit was pretty simple. The order is Kenwood wiring harness-->adapter kit from Amazon-->factory connections in my truck. The wiring is almost idiot-proof as it is pretty much color-to-color. The only discretion involved my truck's OEM amplifier--I needed to connect its control wire and the new amp's control wire to the single P-CONT wire from the new harness. If you understand that all these wires do is turn on the amps when the radio is powered up and turn them off again when the head unit is off, it's a no-brainer to figure out you just need to wire both control wires to this same wire in the harness. To test the connections, I twisted all the wires together and electrical-taped them. Once I confirmed everything was working, I took the harnesses back into my house and soldered them and used rubber heat shrink around the soldered connections. I prefer that to the cheap crimp connectors included in the 1100 amp wiring kit I purchased at Walmart. The one thing that nearly threw me off was the amp's "Protection" light that illuminated after I cleaned everything up and put the trim back on the interior of my truck. Luckily, I was able to search the Amazon user comments and learned that an improperly grounded amp is one of the causes. Sure enough, I removed the piece of trim under which I had connected the 8-guage ground wire to the body of the truck with a screw and saw that I had jarred loose the ground wire when I snapped that piece of trim back in. My advice is, if you get a "Protection" light on this amp, check the ground wire connection before you do anything else. I am amazed at the quality of the sound. The bass is amazing and it's almost like having a new truck. I highly recommend these components.

Great price. Great quality. Have it hooked up to a 12” kicker and it bumps pretty hard and sounds great. Still going strong after 6 months so far. Doesn’t overheat. No issues

Works well, just wish the bass boost was a knob instead of a switch. Not enough power to power a strong sub, but itll do.

Great amp. Easy to wire. Sounds amazing. Installed with BOSS 8 inch subs.

My only worry? Will it hold up or what kind durability and reliability does it have. Background: Been playing with car stereos since the Delco 8-Track and Mind Blower 6 X 9's in my 1974 Monte Carlo. Use a set of Marantz Home Audio speakers and that car stereo absolutely pushed these 150 each speakers with about 99db at 1 watt rating. We'd go to the park, open the truck stand the speakers up and they get almost discotheque loud. They also still held great sound and almost distortion free. The current system sounds better LOL! The system consists of: An old 2005 GMC Envoy, Bose Audio System with surround sound, Center Console with DVD Player and separate sound system for the rear passenger. Everything on it still works that's why I kept it. It sounds good but was never meant heavy music and even Hotel California makes it limit itself. It will not let you blow it (Amp and or Speakers) up playing the music too loud. My goal was to keep this intact but add some punch to it. Goals met and exceeded! First I added a PAC AOEMGM24 Add An Amp Interface. Sweet video on you tube for adding this device to the the Bose Car Audio Receiver. It gave it a 5 star review as well. This took about an half an hour and everything went well. The R1100M Amp was installed in about 20 minutes because I already had a 80 + 80 two channel amp installed. All I had to do is install the remote knob. A snap and took longer to run the wire. I didn't run mine all the way to the back and it barely fits under the driver's seat. I'm only using one 2500 watt (they wish LOL) Pioneer Premier 10" speaker. Its 4ohm DVC is rigged for 2ohm operation. http://img40.imageshack.us/img40/9201/14ohmdvc2ohm.gif and TSW2501-D4. http://www.sonicelectronix.com/pictures_new.php?id=9235&picture_id=-1 Setup worked out to only about 4 on the volume and crossed over at or around 80hz.. One day now and only 10 songs. The reviewers saying it is a very good amp for the money nailed it. So far I'm glad I bought it. This is too much amp for that one 10" speaker. Even with the Volume on the Bose receiver at only at 3.5 to 4, it booms out some of the sweetest lows and easily compare to my 500 Watt JBL SB 120 in the house:) But its louder than that JBL by a bunch. If I had to guess, I'd say 200 Watts clean without any kind of strain. Once setup, it is louder than I want or need but is nice having the ump there if I need it. Sadie's "Ordinary Love". I'm thinking What in the hell is there a boost setting for LOL! As soon as Johnny Guitar Watson's "A Real Mother For Ya" first bass note hit, this thing rocked. Hotel California bass and bass drum shook my review mirror so hard I thought it was going to fall off. Dang I'm too old for this but still love it. Two Higher end twelves or average 15"'s would love this thing. Remote knob works just like it is supposed to. Easy 5 star!

Mono no me gusta

Aunque yo lo instale bastante rústico, la potencia y eficiencia del amplificador es buena, ya lleva 3 meses trabajando casi todos los días (alimentando un Kicker10” Cwcd104 Doble Bobina 500w y está en óptimas condiciones aunque lo traigo todo cochino porque lo instale en mi camioneta de trabajo 👍

Ottima qualità

Bon rapport qualité prix

Por el precio que pagas es excelente calidad de construcción y su circuitería de las más sólidas del mercado, solo que las potencias que dice no son las correctas, para los 4ohm que es el modo que uso mi sub da aprox 200W reales rms, pero por el precio es un excelente amplificador, fácil de instalación y manejo, tiene todo lo necesario para empezar como el filtro de frec bajas, control de ganancia, bass boost por si quieres acentuar alguna frecuencia, y también puede ser de rango completo para usar en bocinas, ademas de incluir el kit que al no ser de alta potencia no ocupas comprar mas, excelente lo recomiendo
