I am looing ot overhaul my cars setup cause it looks like crap, so here's my questions...

1. If I already spliced wired off the factory harness car i put them back on if I left extra wire on the harness?

2.Is a JVC 50+50 and 20+20 amp good enough to power up my spears with a factory tape deck?

3. If not can anyone reccomend good speakers and snall amp?

4. Is there a specific place to wire my amp to so it will remotly turn on when my cars radio/lights/ or radio is on? tha factory has no extra wires left.

5. Is there something for a speakers I can add in the trunk or under the seats cheaply so I can feel the bass but not hear it out of my car? (thats my only requirement)

Thank you to all of you!!!
