MoparMan84, good to hear you are gonna replace the deck. Alpine is great, just make sure that the one you buy has high voltage sub-out. You want nothing lower than 3 period. The higher the pre-out voltage the louder and clearer EVERYTHING will be (sub wise)
To give you an idea of what's out there, Eclipse (fujitsu-ten) makes decks with 8 Volt Pre-Outs. Best in its class.
The whole battery thing is something most people forget about. Once you hit the threshhold of a big system (1000 + RMS Wattage) you have to upgrade your electrical system.
A List of things to change:
Second Battery (not a necessity but HIGHLY, HIGHLY, HIGHLY recommended)
Upgrade alternator ground to 4 Gauge or larger
Upgrade engine block ground to 4 Gauge or larger
Gold/Platinum Battery terminals
Most people overlook these upgrades (the JL manual for the amp lists upgrading engine grounds as a must on page 2) Any system done RIGHT is built like this.
Would you SC or TC your truck without forgin' it? You can but why?
Same holds true for the electrical system. The system will work without these upgrades, but it puts unneeded stress on the sub, amp and electrical system.
Post up if you need anything. I have an entire garage of audio. From fittings, to digital fuse blocks, current meters, voltage meters (for installing in the car Autometer one's) If you can think it, I probably have 2.
Have fun and welcome to the audiophile community:rock: :rock: :rock:
Oh almost forgot, make sure you take a vid of the sub moving hard. The guys on the forum will freak when they see how much excursion that thing has!!!
