So for an audio setup I wanted a mild system so I bought a 250watt TMA amplifier. I also have a Blitz Audio in line driver to adjust the inputs for even better tuning. I kept everything well hidden and clean looking, I just need to replace the plastic carpet molding that goes across the back seat. For a sub I have a MTX 10'' Jackhammer which sounds real nice im my custom made box. The head unit Is a Sony with adjustments for low,mid,high, and sub output. It's the best sounding headunit for a sub that i've found yet.
