As a Jyotish astrologer, I can say that Mars in the 4th house in Aquarius sign can have a significant impact on an individual's life. Mars represents aggression, courage, and energy, while the 4th house is associated with one's home, family, and inner peace. 

When Mars is placed in the 4th house in Aquarius, it can make the individual quite active and aggressive in their personal life. They may have a strong urge to always be active and on the move, at times leading to conflicts with family members.

However, Aquarius is a humanitarian sign, and when combined with Mars, it can bring a selfless desire to serve others. The native may work hard towards social causes and helping people in need, bringing a sense of fulfillment to their inner peace.

Overall, the placement of Mars in the 4th house in Aquarius sign can create a unique balance between personal ambition and a selfless desire to work for society's greater good.
