Deluxe 4-Channel Compact Class D Amplifier 4 X 150 Watts Rms @ 4-Ohm
Default Title
Perfect amp for the 4 speaker set up
For Harley . I also purchased the plug and play harness when I got the Amp , easy install . Only item
I didn’t get was the rear speaker backbone harness and ideas able to get it from Amazon . As with all the DS18’items I’ve received the quality is excellent , have a Jeep with all DS18 equipment.
This amp fits behind the fairing on my harley. Speakers sound so much better
Installs easily behind the fairing. Runs surprisingly cool and puts the 150 rms power to my DS18 speakers with little to no distortion. A great powerful clean amp.
This thing fit perfect on top of the radio on a 13 ultra powering a set of 6.5 ds 18s and super tweeters in the upper fairing and a set of 6.5s in the lowers and it makes all of my speakers kick sounds awesome
Installed this amp on my 2022 street glide. With 2 Pro-ZT69 and 4 Pro-ZT6 and let me tell you. Sound way better then all does over price kits on the market.

Wayyy more than I thought great for the price thanks ds18
Good speakers loud and clear
They fit perfectly and they sounds awesome, I definitely recommend them friends of mines are planning on buying them as well
I have (4 ) of these DS18 XL 12s midbass loudspeakers on my stuntwall with a GFX 5K powering them @1 ohm, and they sound absolutely amazing. I have them paired with the (6) Ds18 DKH1 horns that is also on the stuntwall. I couldn't be any more pleased on the sound that it produces.
Very nice product, highly recommend using this on a ATV
Made my sound system complete made it sound way better worth it saving up for the passenger side
I received it haven’t gotten the chance to hook everything up. Still waiting on the rest of my setup to come in.
So i was a DS18 hater for a long time because the "loud" guys would buy the cheap 6.5" louds no tweeter and it sounded awful always. i heard these 6x9 pros and had my mind blown they are clear and clean but also so efficient and loud. i put mine in my 95 honda accord i am running active with a 8k crossover on the tweeters to get those highs. set up is pioneer prs80 with a 5 channel rockford with channels stacked to have active front and back. most people are blown away by how clear it sounds and just how loud it goes. i do have ds18 2.5" Dome Neodymium Tweeter in the front with 6.5" krome audios i was given. now i'm not a wealthy person the headunit is old and tape is holding things and the amp was fix by me after a guy blew up a soda in it and than threw it out i grabbed that cleaned it 5 years later still rocks. i say all this because these speakers aren't the cheapest i saved up but it's worth it they seem well built i play them loud and a year later just thumbs up. thanks ds18
I have this speaker crossed over at 120 htwatts, pass, with a 24 dB slope at 250 watts, it's loud, but better yet it is crystal clear. If they had more I'd buy more.
Bring them back ds18, bring them back. I have 2 other cars with some 6.5 inch vacancies.
