    Got the S1-2250 on 2 hds3.1 12s @1ohm and it knocks hard AF in my car !!! Dont hesitate or think twice about placing an order with Soundqubed, great customer service and shipping can’t be matched as quick as I’ve got my orders .can’t wait to get another 2250 and strap them baby beasts to a pair of hdx 15s next

    Cannot say enough about this company. I did alot of research before deciding on Soundqubed and they exceeded my expectations. I got 2 HDS3 15’s and the SL2250. WOW!! Lots of power and they sound so tight clean and crisp. I saw a dyno test done on this amp on YouTube and it exceeded the listed power ratings. Awesome products, customer service and delivery times. I received my packages in 2 day which was 5 days earlier that the scheduled delivery date. Their prices can fit just about anyone’s budget and I dont think you can beat the performance at their prices. I highly recommend SoundQubed. Keep up the great work SQ!!!

    I hooked this amplifier up to a single Soundqubed HDC315 in a custom box built from the cut sheets on this website for a single ported 15inch subwoofer.
    The quality and power is unrivaled in the industry. The customer service I receive from Soundqubed is very polite and professional.
    Do yourself a favor and purchase Soundqubed products. You will be very satisfied.

    What a great amp from a great company! This amp is amazing! Puts out rated power with a nice price tag! I paired it with 4 hds 12’s and it really pushes them! Will go great with the s4-100 i’m going to be ordering! I can not say enough good things about this company! There quality with these prices are just outrageous! I’ve called a few times for some questions on other items and every time i’m stunned at the customer service I receive! Very friendly and willing to do anything to help the customer out with whatever is needed! I will be recommending to everyone and will defiantly be buying more!

    I was really hesitant to order this amp due to the power it claims and the price point! Really happy I decided to do it, to be honest. I’m sending my AQ2200 in for repair and needed something to replace it in the meantime. This amp has definitely exceeded my expectations and I cannot tell a difference in power between the two. Just hoping that it lasts as long as the other one that I plan on keeping as a backup once it’s fixed.
