This 300-watt upgrade boosts the overall sound performance of the factory sound system. The PSU-300ACD consists of an 8-inch powered subwoofer, Compact 4-Channel amplifier, and a remote bass knob. The system is compatible with 2018-2020 Honda Accord 4-door models (LX, Hybrid, Sport, e) that do not have the optional factory Premium amplified sound system and are not touring models. All the components are hidden away, so no valuable Trunk storage space is used. The subwoofer is just 3-inches Deep at its tallest point, so it and the amplifier fit neatly under the front passenger’s seat. Aside from maintaining storage space and utilizing a hidden installation, placing the subwoofer close to the front of the car allows for a proper sound stage in front of you, ensuring the best bass and imaging experience. The PSU-300ACD is designed for plug-and-play installation, which reduces labor time and gets you on the road quicker. The subwoofer and amplifier are pre-assembled onto the accord-specific bracket, so there’s no guessing where the products should be installed and no time spent connecting them to the bracket. An accord-specific wiring harness is included, so no extra parts are needed. The bass knob mounts onto the dashboard so you can make bass level adjustments from the driver’s seat. The PSU-300ACD is compatible with the factory Honda base radio, an Alpine Universal head unit, or other aftermarket radio. The PSU-300ACD is authorized to be Sold By and Shipped From desertcart. For professional installation, visit the store locator on the Alpine USA website to find an authorized Alpine retailer near you. Review: Night and day PERFECT BALANCE - Just finished the install, probably the nicest, cleanest we’ll thought out all in one system. The difference from the stock system (which we all know is junk) is crystal clear loud non distorted music you would expect to come from a 30k car in the first place. If you are on the edge about pulling the trigger on this just do it before they are all gone because alpine quit making them. Cheers. Review: Perfect fitment & easy plug and play - If you have a Accord and hate the factory sound system this is for you. Won’t wake up the neighbors but sounds amazing inside the car. Once again this is a must buy. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07K4RY6J6 | | Antenna Location | electronics | | Brand | Alpine | | Built-In Media | 8 x 1/2” Phillips truss head screws with star washer, Amplifier Bracket Assembly (1) [consisting of pre-assembled 4-channel amplifier, 8” Powered Subwoofer, Amplifier and Subwoofer Left/Right mounting brackets, M4 screws with washers (8), and 8-32 pan head Phillips screws (4)], Cable ties (10), Installation Manual, Main Harness, Power Cable, RCA adapters (4), T-Harness | | Compatible with Vehicle Type | Car | | Connectivity Technology | RCA | | Control Method | Remote | | Controller Type | Remote Control | | Customer Reviews | 4.4 4.4 out of 5 stars (7) | | Global Trade Identification Number | 00793276242679 | | Is Waterproof | FALSE | | Item Dimensions D x W x H | 21"D x 18"W x 3"H | | Item Weight | 14 Pounds | | Manufacturer | Alpine Electronics USA | | Model Name | PSU-300ACD | | Model Number | PSU-300ACD | | Mounting Type | Trunk Mount | | Number of Items | 1 | | Power Source | Corded Electric | | Speaker Maximum Output Power | 300 Watts | | Speaker Size | 3 Inches | | Speaker Type | Subwoofer | | Subwoofer Diameter | 8 Inches | | UPC | 793276242679 | | Warranty Description | Manufacturer’s warranty can be requested from customer service.
