Product Overview

I recently had the opportunity to test out the NVX QBUS8P 300W Peak 150W RMS Amplified Loaded 8 Ported Under Seat Quick Bass Universal Subwoofer System with Remote Bass Knob. I was pleasantly surprised with the results. The system is incredibly powerful and provides great sound quality.

The NVX QBUS8P is designed to be a space saving solution for those who don t have a lot of room in their vehicle for a subwoofer system. It packs a punch, boasting 300 watts of power, and has an 8 inch ported subwoofer that gives it plenty of bass. The low pass filter allows you to fine tune your sound from 50 150Hz, and the variable bass boost allows you to adjust the low end according to your preferences.

Installation was easy enough it takes either high level speaker wire or low level RCA inputs, so it s compatible with both factory and aftermarket units. Additionally, there s an automatic turn on circuit that senses when audio signals are present, eliminating the need for a remote turn on wire.

The sound quality is great it really adds depth and clarity to music. I tested it out with several different genres rock, rap, EDM and was impressed by how well it performed across them all. The bass was particularly impressive it had a nice punchy sound without being too overwhelming or muddy. It also had good clarity and definition throughout its range.

Overall, I m really happy with this product and would highly recommend it to anyone looking for an underseat subwoofer solution that doesn t take up a lot of space but still packs plenty of power. It s easy to install, sounds great, and offers excellent value for money considering its features and performance. If you re looking for an underseat subwoofer solution that won t take up much room but still has plenty of power, then this is definitely one worth considering!
