"I just purchased this for my Smart Car Cabrio along with a pair of 6. 5” door speakers. WOW, what a great upgrade. The sound is amazing and the sun remote adjuster gets the perfect amount of bass to compliment the different types of music. Install was easy and the compact size fit right where I needed it. Rockville Audio products are great quality and great value."
"Sound perfect for what it us"
"Works great. No issues so far. Good little subwoofer at a great price"
"Put this in my 2010 Jeep Wrangler. Ran from the battery to under the passenger seat. Simple install and this thing hits good enough for me. Mainly punk rock I listen too with old New York Hip Hop. This covers all the bases. . ."
"I installed one of these under the back seat of a Ford F-150 crew cab. The factory stereo was upgraded with 4 JBL 6x8 coaxial speakers and an “add a subwoofer” wiring harness. I ended up using a 12V cigarette lighter adapter plug for the blue wire because Ford makes it virtually impossible to add any accessories. This little subwoofer packs a punch, right out of the box with only a tiny increase in gain and bass boost needed. The metal cabinet feels very solid. I used Velcro strips to attach it to the carpet. Outstanding value!"
"I have a 2000 jeep xj and the sound system was less then par. With the new Rockville 400 8"" sub it is now on a whole new level. The sound quality has enhanced my driving mood. I suggest this to anyone who wants to bring back their 20's without hurting their hearing, lol. My kids and I are enjoying our rides and offroading more than usual. Thank you Rockville for a great product and the wire kit that made it a breeze to install."
"The speaker sounds good and was just what I was looking for. Big sound out of a small package. The power and ground wires are good quality. The harness however could have been built a little better. Before even wiring up the speaker, the blue remote wire came out of the quick connect harness. Was not easy to reattach but I was able to make it work. If the harness was better quality I would have no complaints at all."
"Sub sounds good the high input auto turn on doesn’t work on mine already had it mounted and wires run had to add a switch. Shipped in a timely manner"
"I was not expecting much when I installed this sub. I have to say that it far exceeded my expectations. It is awesome and I will be recommending this to every stereo enthusiastic person I know. Great job and American made."
"I recently installed the SS8P and I am thrilled with its support for the system I installed. Paired with my Infinity speakers, this unit provides a powerful bass response that compliments the sound dramatically. It's compact size and awesome price is welcome addition for placement and for the wallet. Will look for future purchases from Rockville."
