Car Audio...what upgrades do i need

Really if you want full potential you will want 2 capcell batteries Ond for each amp. But always remember your vehicle will only let so much power out . Cause the highest oem alternator only puts out 105-125amps . Sobif you want the best an loudest you will want to upgrade to a 200-300 amp alernator if not you will wear your stock alternator out an be replaceing it. Plus it never matters how big a amp is with a high watt subs if your car don't have the power to push it your wasteing money by buying all that nice stuff. What I'm saying is if I buy go cheap 15" subs an a low watt amp with your stock alternator it will sound same. So please take advice from experience increase your Amps on your alternator . I promise you then will have no problems.

Also with have a 800 amp capcell your car stock can never charge it trust no matter what an audio place says you will want to order a hough amp alternator it will be a special order . If you do everything right with what you have already bought it will be no problem hearing you from a mile away or mire

You can order two hough amp alternators hook them both up parallel with a costum made bracket or you can probable order one. Don't forget the compasitors they help alot if one can't aford a alternator. Hook them up just before the amp. You should have a batt. and a compasitor for each amp. Make sure the primary wires are bigger than it says in the manual. for examlpe a 800 watt system would take a #10 gage while a 20,000 watt would take a #2/0 cable. I have a #4 on my 1,080 watt amp, it's a small amp but I got to 12's in a 11/2" thick seald box that was made for two 15" subs. What I did is use less power in a large area to produce a deep ponding tone. It puts out 90 db at 30 hertz.
