DS18 X4 Amplifier 4-Channel Ultra Compact Class D 4 x 70 Watts RMS @ 4-ohm, Stereo Full Range, Car Audio Amplifier, Great Compact Amp for Motorcycle, Powersports

Fantastic little compact amp, for cabin of my sailboat. Very efficient, and just the right amount of sound power for my little Garmin Fusion stereo. Two front channels for 6" speakers and two rear for single 8" sub. Note, I at first thought it was dead, but then realized I need to add 12v to the middle power terminal (turn-on lead). Duh.

Absolutely perfect for a small setup like a motorcycle. I have this running two 8", 2-way SKAR Audio Marine speakers in 8" Audiopipe cans. No complaints what so ever. Very compact. Fit in the compartment under the rear plastic where my tool bag used to be. 5 stars all the way. 💯👍

Best amp in the market so small it fits anywhere

I purchased the Compact Amplifier with high hopes it was the only one small enough to fit in my motorcycle. For the first couple of months, the device worked like a charm, delivering clear sound and amping up my radio's performance. I was genuinely impressed by its compact design and the noticeable improvement it brought to my listening sessions. However, my enthusiasm quickly waned as the amplifier unexpectedly stopped working altogether. It's disheartening to invest in a product that initially demonstrates so much potential, only to face such an abrupt breakdown. I tried troubleshooting, checking connections, and testing different setups, but unfortunately, nothing revived the amplifier. While the initial experience was promising, the amplifier's sudden failure has left me feeling disappointed and frustrated. It's disappointing to see a product with so much potential fall short in the longevity department. I had hoped for a reliable audio enhancement solution, but unfortunately, this product didn't meet those expectations. In the end, I find it difficult to recommend this product given my own experience. The potential it showed initially was overshadowed by its short-lived performance. If you're considering purchasing this amplifier, I would advise proceeding with caution and being prepared for the possibility of encountering similar issues down the line.

If you are looking to put an amp in your Harley, this is the one. I put this in my bike and I only run two front speakers which are Hertz and it works fantastic.

Would give 5 stars except the first one that arrived was clearly used velcro stuck to the back corrosion on the screws and only functioned momentarily amazon resolved the issue for me quickly. the second one functions well it's loud and clear according to ds18 the warranty when buying on Amazon is 1 year and directly from them 2 years just for information

Brought these in Feb 2024 to build my system on my Harley and as u can see they both definitely fit inside the front fairing comfortably absolutely perfect nothing needed to be modified to fit and the front fairing went on without a problem. They definitely pack a punch as I have 1 amp running the front 4 speaker and the other running the rear 4 inside my saddle bags the clarity is astonishing they are paired with 4 ds18 pro 6.5s and 4 ds18 pro 6x9s absolutely love them

This compact device packs a big punch! Worth the money and is slightly bigger than an iPhone 14plus. It will fit inside the fairing of a motorcycle, you probably could fit two of them in there. UPDATE 3/14/24: Went ahead and purchased a second one so that the power is not divided. Thoroughly read the description, ONLY the AMP is a part of the package! #Wire up correctly
