Review: What started as a stereo and new speakers has blown into a system that's nothing short of AWESOME! I know there are those who ha - I bought a 1996 Classic Silverado truck that had the original stereo with separate CD player that needed replacing. I rely heavily on reviews before I make any purchases but I decided to "roll the dice" on the Boss 650UA. At 50+ years old I didn't see the need to spend huge money on a stereo for a standard cab truck. One concern that I had was compromising quality for price. WRONG ! What started as a stereo and new speakers has blown into a system that's nothing short of AWESOME ! I know there are those who have unlimited funds that spend thousands on a great stereo, I'm not one of those people. I bought the Boss 650UA Head Unit, Boss CH6530 Chaos Exxtreme 6.5 " door speakers, the Boss CH4630 4x6" speakers for the rear posts and a Sound Storm EV 400 4 channel amp. It sounded pretty good but lacked bass. I could have stopped there but I continued to improve the system over the next two weeks. Next was the Sound Storm SSL S4EQ Equalizer. (Sound Storm is Boss). Then I bought 2 Boss Audio CXX10 Chaos Exxtreme 800 Watt 10" Subs and a Boss Audio R1100M Riot 1100 Watt amp to drive them. I was on a roll so why stop there ? lol Next was the Boss Audio NX694 6x9 4 way 800 Watt full range speakers with a Boss Audio PT 1000 Phantom Amp to drive them. All packed into a Standard Cab truck. lol Also bought a 2 Farad Capacitor and a Power Distribution Block just to be safe. Getting ready to complete my system with 2 Tweeters and then I'm finished. So with everything said and done I have less than $ 400.00 into this entire system and let me say it ROCKS ! No engine noise, no distortion, just crystal clear and clean music at an affordable price. The 2 Subs under the seats sound fantastic ! I could have bought the Clarion, the Alpine etc., and the price tag would doubled or tripled but for me this is an awesome system that's worth every penny. If I had it to do all over again I wouldn't change a thing ! My suggestions would be TAKE YOUR TIME ! It's any easy "Do It Yourself" install if you follow the wiring diagrams that are provided. Also use the thickest gauge wiring that you can -Amps, Speakers, Battery, Ground, etc.. Don't buy a great system and then skimp on the wire ! As far as the negative comments go, I would ignore them. Boss makes quality audio at affordable prices. I would have to recommend Boss Audio to everyone !!! Comment Comment | Permalink
Review: Replaced stock speakers. These speakers sound great and clear. - 2022 Nissan Frontier. They sound amazing which they should since I was replacing stock speakers. Magnet was bigger than opening on door so I had to use a grinder to make it fit. Absolutely happy with the sound.
