Kenwood as a brand has great heritage in car power amplifiers, some of you maye recall some of the award winning power amplifiers in the 1990's - 2000's . I remember products such as the PS series those amplifiers would give tremendous power output with excellent sound quality.
These days amplifiers needs have change quite alot and we now need less power, cleaner sound and more compact solutions. One thing you will notice about the Kenwood X301-4 is just how compact the amplifier really is. When I opened the box and held it in my hand it is smaller than a piece of A4 paper! Now that is small for a power amplifier. In fact its about 25% larger than A5!
The amplifier is beautifully constructed, being class D it is light weight as the power amplifier is very efficent at creating power. So less heat is generated and you have a more compact size in return.
You have front and rear line inputs Bass boost upto 18db Variable high and low pass crossover on both front and rear channels - this means you can use this amplifier as just a bass/ mid to high on front or rear or all channels....that is rear! Speaker and power terminals are of a good size allowing for correct wire sizes to be used.
All inputs and outputs are covered by end caps giving protection.
Sound Quality wise you will find the amplifier very dynamic, clean and punchy. The bass is extremely acurate considering the power output. Midrange is very direct and focus and the high's are nice and linear.
Overall this is a great amplifier if you want to add that little bit of extra power with great sound qualuity. An absolute must in my book.
