Engineered for those who demand nothing but the best, this 2-channel converter delivers pure, unfiltered sound with seamless integration into any vehicle system, whether OEM or aftermarket. Advanced transformers and cutting-edge noise rejection technology ensure that your audio remains untouched by interference. Plus, the QHL2 requires no power supply, further reducing the chance of ground feedback noise.
Installation is a breeze thanks to its compact, rugged design, complete with a detachable harness and straightforward labeling. Versatility is at its core, the QHL2’s Double-Step Down Ratio allows it to handle both high-power (6.5:1) and low-power (4:1) sources, making it the perfect companion for any setup. With built-in speaker emulation, the QHL2 guarantees flawless integration by ensuring your OEM source detects the original speaker load.
The QHL2 doesn’t just stop at superior sound—it’s smart too. The intelligent +12V remote output automatically triggers your amplifiers, with LED indicators for easy monitoring. Only the auto turn-on feature requires power, ensuring minimal impact on your vehicle’s electrical system. And with its durable aluminum housing and tear-proof wiring connector, you can trust it’s built to last.
Disclaimer: Ensure your vehicle's electrical system operates at 12V DC with a negative ground.

Puts out amazing power
Bought these to install in my 24 road glide after the update Harley just did they sound amazing but I did need to purchase some spacers so the fits properly
Really good power and 0 dimming on lights since installation and the battery itself looks amazing. I like that it can be laid on its side if needed.

DS18 BB5.6UF/100V-10PK 5.6uF 100V Non-Polarized Bass Blocking Capacitor
I needed to upgrade one of my amps to have more rms to the new set of door speakers I am running. There powering ds18 neo series. And the way I needed it mounted under the seat there was no way a normal amp would fit. For a small foot print pumping out over 200 rms in a reasonable price this met the needs. Haven't had to worry about clipping with this amp like the other one from another vendor.
I love the Infinite INFINITE 35 AH battery installed it on my 2013 Can Am Maverick 1000r and it has enough cracking power to start it every time see how it does when i add accessories
I love how there loud and everything but I had one go out on me
5 STAR!!! Installed these speakers in my 2019 Road Glide and I could not be happier with the clear sound!
Loud asf crystal clear
Really nice kit, AMP is also very solid and compact, fits nicely under the seat on the low profile AMP rack I bought !
Would recommend taking to a shop for installation. I’ve got a 2025 Jeep Gladiator and my only complaint is how difficult it is to disassemble the dash.
Also note this is not exactly plug and play if you intend on Amplifying tweeters and Dash speakers. These are extremely Loud and clear on Vocals.
If you plan on doing The Sound bar too, you have two RCA’s labeled FR & FL. You need a RCA Y splitter, DS18 Makes them. You actually need 2 red and 2 black splitters. Would highly recommend the speakers if you’re looking to Wind Proof the audio.
Never had subs this small but was suggested to try it and happy I did! I had 2 12s in my gladiator and wasn’t to happy with it and tried 4 of these and the sound is night and day difference! I have them in a ds18 ported box on a FR 3.5k
Have not installed them yet but the quality looks Superior
