Melissa Hall is a competitive female basshead with not just one but two builds! She is a veteran basshead, with 30 years of experience installing and building her own setups. Currently, she is the vice president of Team RoyalHittaz. Car audio has always been a part of her life, but she took a lot of inspiration from Ole Silver at Triplefest. She says, “I went to Triplefest and saw Ole Silver, she was a rusted-out old truck from the outside but had a beautiful build inside…I fell in love with the epoxy, huge amps, and adrenaline from feeling it from across the parking lot.” You can follow her, build progression, and her latest work here.

 

2004 Toyota Sequoia – No Wall

 

Electrical

The electrical in Melissa’s Sequoia consists of a 390a Singer Alternator, two 45ah Limitless Lithiums, and Sky High Car Audio wiring throughout. The 45ah Limitless Lithiums utilize the LiFe PO4 (lithium iron phosphate) chemistry. These 45ah lithiums can support up to 8,500w and 12v with 300a of available charging. This is equivalent to 4 100ah AGM batteries.
