We know some audiophiles can never have enough speakers. Multi-channel car amplifiers give you the power needed to run the stereo systems in SUVs, full-size vans, luxury sedans and other large vehicles — or to go all-out in a commuter car. Each of the amplifiers on this page has at least six channels, letting you run every speaker and subwoofer you could possibly need.
As an authorized dealer of the top brands in car audio, OnlineCarStereo.com has the latest multi-channel amplifiers for sale. Shop online or visit a brick-and-mortar store for amplifiers from Sony, Alpine, JBL, Audison and others who know sound. Each amp is backed by a 60-day guarantee and our lifetime tech support.
No matter what your audio demands are, there’s an amplifier that meets or exceeds them. We carry a wide assortment of 6-channel amplifiers and 8-channel amplifiers. A 6-channel car amplifier can power four speakers and two subwoofers or be bridged to run an extra-loud 2.1 system. Bridgeable 8-channel amps offer even more options, effectively letting users build a custom system tailored to their speakers and subwoofers.
You’ll also have a choice between Class A/B and Class D amplifiers. A/B car amplifiers offer better sound quality on high and midrange frequencies while Class D multi-channel amplifiers are much smaller to fit in tight dashboard spaces. You can also sort by power range, frequency response and fuse rating to find the perfect amp.
If you need assistance, use the Vehicle Fit Guide or call our customer service reps Monday-Friday. They’re experts in car audio and will steer you in the right direction. We have many other essential car audio accessories as well, such as car batteries and capacitors if you need some extra juice to run your new amp. Everything ships free in the lower 48 states so you get an even better deal on high-quality stereo components.
