    • Great little amp for the money
Color: Black
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. ... show more

    • Will not power your band's instruments.
Color: Black
I am an electric keytar player in a post pre-ironic hardcore pop metal band called "Peace Strangle," check out our latest demo on Myspace. Anywho, we travel to some pretty big venues like Chuck E Cheese, or the Wendy's parking lot. You name it, we have played it. However, about 2 months ago the band was offered an opportunity we couldn't pass up. A chance to play at president Putin's favorite Ihop in Moscow. We knew this was how we reach our demographic that we have been struggling to connect with, Communist. So we graciously accepted and began preparing ourselves for the show in Russia. We had a couple weeks to get ready for the show on June 12th, which is Russia Day for the country. So we got plane tickets and all the prep done, and had been practicing like crazy. Until, the last few days before we had to leave one of our amps blew a fuse. Well, Snickers! Alright, so we scope out online quickly for a reasonable and functioning replacement. We stumble across this amp, and thought we struck gold. 1100W Amp for that price! We bought it on the spot with a couple day delivery. We ran into some more unfortunate circumstances when Salazar's paypal didn't process the request right away, it had a day and a half lag. We got our new amp at 8:03AM Jun. 12, we had to be on the plane for Moscow by 10:15AM. We didn't even unbox it, threw it in the band van and booked it. We made the flight with about 4 mins to spare. ALRIGHT MADE IT! We enjoy our 9 and a half hour flight in various ways. Salazar likes to do this thing where he speaks in different dialects to screw with near-by passengers. He once pretended to be a blind Rastafarian for an all day flight from JFK to Tokyo, it could have won an Oscar. But I digress, we arrive in Russia and are immediately swept off the plane by Putin's private security to be escorted to the Ihop where we were to preform. When we pulled up the place was a mob, thousands, if not hundreds of people were crowded around the joint. Only a handful of people were actually inside the pancake house, one of those people being Putin himself. We pushed through the crowd along with the smell of vodka and potatoes. All of our equipment was set up and ready to go for us, everything except our new amp. Which had been opened but not set up, we point this out and state how we need the amp for one of us to use. Without batting an eye Putin shoots a look at one of his men, who then proceeds to start yelling in Russian to a near-by worker. They seemed really excited by our soon to be show. After a few mins of setting up the amp, we are finally ready. I decided I would use the new amp since it was really low to the ground and my keytar could reach fine. We start our setlist off with one of Putin's favorite songs by us( One of his men mentioned it on the way to the show.), " Murder Love Remix." Now everything seems to be going great, everything sounds and looks good. My part of the song doesn't come in until after the bass drops but before the metal drum solo, so about 3 mins into the song. I start to play my part, only to have the amp blow up, killing the lights and sending metal shrapnel in every direction. It was at this point I heard Col. Heinz Salazar shout, "FLASHBANG OUT, GO LOUD!" At that moment Lt. Dan Taylor and Sgt. Frank Woods(The Guitar and Accordion players.) cocked back their hidden rifles in the instruments. They wait for the flash, and let loose a barrage of controlled burst into anything and anyone in the Ihop that wasn't us. As my three "bandmates" lay down suppressing fire, it is time for my part of the plan. I slam the C-major cord and flick the pitch switch back and forth 3 times as I do, this initiates the reaction. Enough C4 and thermite to level a small country, it was set to blow up in a circumference 5 miles around with the epicenter being the Ihop. This was too slow any attempt to try and detain us and provide an in-direct LZ. The silence that followed the blast, was deafening. Only broken by a coughing injured Putin, wide eyed and clearly befuddled. Col. Salazar looks in to the Russian president's eyes and said the following, " Good evening sir, we are from the United States special forces. We are here to take you back with us for....questioning?" The lack of understanding in Putin's eyes seemed to irritate the Colonel, but before he could have acted on it, we heard the Blackhawk closing in on our LZ. We restrained Putin and the 5 of us headed to the roof for extraction. As we were leaving I took a small piece of the amp that was laying around for remembrance sake. The helicopter ride to the hidden plane on an unmarked runway was blissfully calm. When we landed at the runway, we were greeted by 4 of the most politically powerful people in America. They congratulated and thanked us for unrepayable debt of heroism and patriotism. We were debriefed on what "we needed to know." We never saw Putin again, but this amp was the start to a much needed revolution. But it won't power your band's instruments. 5/5 Would Vladly buy another. ... show more

    • Budget freindly and comes with bass knob
Color: Black
It works well but it does produce a lot of heat and it’s easy to put it into protect mode but overall great quality for the price .. gets the job done if u need something to hold you over .. still creates a boom worth playing.. songs may vary and pairing it with 12s is as low as I’d go in terms of subs .. ... show more

    • Great value, great product
Color: Black
I am blown away with the quality of the materials used to make this amplifier when compared to the cost! I have been installing car audio systems for over 20 years and never bought anything Boss has made before but I am very pleasantly surprised with the quality. For just a mono block amp this is very well built using good materials and sounds amazing. Very well done. ... show more
