This is all you need. It beats hard. Sounds great. I'm very happy with the purchase. With 2 year warranty it should be good to go.
This set up is the best bang for your buck period. As you see I am running both 18” subs off of the RP 800.1d amp that came with the package during break in.
I wanted to get back into car stereo after 20 years out of the game settling for stock systems. I purchased this 18" subwoofer/amp package when I bought a 2004 Tahoe to "play" with and this is BY FAR the most bass I have ever had, especially for the amount I paid for it. I had just about every size subwoofer and amp possible back in the late 90's and early 00's, and my last system was all Alpine and triple the price...pfffftttt! Where were you SKAR when I was a poor 20 something trying to tweak my amps in the wee hours of the night? I am beyond satisfied with this purchase and have already suggested to a good friend to buy something similar for his SUV. Seeing as how he helped me install this beast I will be happy to help him when he pulls the trigger.
Just got it installed last night.... I love it! My mistake was not paying attention to the length of the wires. I have a 2000 grand marquis. Very lengthy car, so amp is on the floor behind my seat. I needed a few more feet. But OVERALL- the sound quality is perfect!
Have to return it when installed make a weird noise I sent a video waiting on how to return
