Okay, my lady friend is wanting to get a sound system in her saturn. She wants it ground pounding, but on a budget...so I'm thinking 2 10" E-10D4 Sundown audio and a MB Quart ONX1.1000D amp, since I know sundowns can take more than what they say. A Knukonceptz 4 gauge amplifier kit will be the power wire running this.
What will be needed to upgrade so her electrical system doesn't take a crap on her.
-Big 3 upgrade is a must.
Would she need a second battery in the back?
