The Quantum Audio Cozmik series QCA4000D 4,000 watt mono-block car amplifier has the nicest design we have seen. This is a class A/B amp so you can be sure the power is extremely efficient. This amp has a built in low pass crossover network so you can fine-tune and adjust the bass frequencies.
This amp is way more powerful than the cheaper brands who rate there amps at 6,000 watts. These amps are rated and tested during production. Quantum is known to make great sounding amps. We guarantee you will not be let down by the performance of this amp. This amp will make your subs sound extremely loud! In terms of sound quality, this amp is top of the line! It has a built in sub-sonic filter, which is only found in high-end bass amps, such as this one!
We have tested these Quantum amps against some of the headliners in the industry such as Sony, Kenwood and Pioneer and these amps time over time outperform the competition. If you are looking for top of the line quality without overpaying this is definitely the amp for you and we guarantee you will be impressed with the performance. (We were blown away with how good these were when we tested them)
Other name brands spend a ton of money marketing there products, so you are not really getting what you are paying for. With Quantum you get way more than what you would pay for an amp at a similar price, labeled under a different brand name.
