Disclaimer: This amplifier will require an additional charging system to run efficiently. It will run without the additional charging system but you run the risk of damaging the amplifier and/or not getting the optimum power out of it. The additional charging system includes the Big 3 upgrade as well as adding an AGM or Lithium car audio battery. All of our amplifiers are age tested for an hour before going into stock.

The Q1-4500.1 is one of the largest and most powerful SoundQubed amplifiers. It can push more than 7500 Watts at one ohm @ 18 volts. Strap two Q1-4500.1’s together for over 15000 Watts at 2 Ohms, stable.

This mono amp has on-board features to fine-tune and dial in the tone your specific application needs. The variable 20Hz~200Hz low pass filter operates on a 24-decibel slope to remove high frequencies from your subwoofer mix while still allowing the bass to bite through and burp.

An added 10-50Hz subsonic filter makes sure that extremely low resonance does not cause unwanted distortion in your car audio system.

The Q1-4500.1 subwoofer amplifier is made for pushing heavy-duty drivers like HDX4 subs and anything else down the line with ease. Its uncompromising build with 4500 watts of power is made for serious car audio installations, sound pressure level competitions, and extreme audiophiles searching for the ultimate in sound quality and deep bass.

For Extreme Competitors: Strap a pair of Q1-4500.1’s to each HDX Sub in your build for SQL and SPL competitions.

Beware, if this burns or folds a cone, you will need a new subwoofer or a recone kit. We do not warranty burnt or open coils or competition use of subwoofers and amplifiers.

Two in-line 400 Amp fuses drive this bass monster with Korean circuit boards that feature MOSFET switching. Four-way protection circuit safeguards include speaker short protection, making sure your SoundQubed car speakers and subwoofers.

DC offset protection is present so you can enjoy the best possible listening experience. High/low voltage and thermal protection are also present in the four-way protection circuit so your new Q1-4500.1 lasts a long time!

    Have this pushing 6 of the original SQ HD 12’s and holy crap I can’t even turn the gain up at all!!! THIS THING IS A MONSTER!!!!!

    I have a pair of these strapped on 4 sundown Xv2 15’s and let me tell you they definitely are some solid and stable amps! I’ve seen them ran at half ohm and pushed hard without ever breaking a sweat but I personally have mine at 1ohm each for a 2ohm final and I see plenty of power from the pair to get high 50’s on music and if I were to play with it and add bracing/bunch more deadner play with port tuning I know I could very easily break 160db but I’m happy with it tuned low and giving groundpounding demos lifting girls hair and freaking them out lol mind you this is a “No-Wall” setup using traditional old ported sub box so again if I walled off my yukon denali I’d be replacing windshields more frequently than I have to now! For the money, these are going to be your best option for strong/reliable korean power! Mine been slamming for 4yrs+ without a single issue…. Make sure you’ve upgraded alt and have plenty of battery reserves these things are beasts!

    I had two of them strapped to 4 HDX threes with a deep cell lithium battery bank in a custom ported box at 30 Hz it was on real monster monster let me tell you right now these amps are worth it you can piggyback as many as you want together if you can find them they’re never in stock definitely a rare item at this point worth every bit of the money though promise you that
