I recently purchased a JL 1000/1 v2 slash amp to power a JL 12W7 sub in a ported box. I am using 4 gauge wire. However, I have read of people having alternator problems or voltage errors due to using the amp (it is supposed to be very hungry). I drive a 2008 Pontiac G8 GT. My questions are:
1. Do I need a 2nd battery?
2. Do I need to do anything to the alternator?
3. Would it be worth it to get a 2 farad capacitor? I have heard mixed things about capacitors. The guy at the audio shop told me they are like bandaids and won't help much. However, I do not want my headlights dimming and would prefer to minimize load on my electrical system. Would a capacitor help for these things?
Any other comments or feedback regarding this setup? I don't know anything about this stuff so if someone could look up the electrical information on the G8 GT and let me know how this amp would fair and anything I would need to do, that would be great!
