Interesting post and I can understand that side of the coin. I guess we assumed he did 1 and maybe 2 from your list considering he sells audio...I've hardly ever heard of anyone adding a second battery or upgrading the alternator for a regular sound system (not some crazy competition-level sound system). I know that in my previous experience (mid-2000's) that I did NOT upgrade my battery and did NOT upgrade my alternator. I just made sure my wiring was top notch (gauge, length, etc.) and added a cap and I never had any issues with draw and I had some pretty decent systems.TDot wrote:Before I get into that here is car audio 101. When having power issues you upgrade in the following order.
1/ upgrade battery ground, alternator ground, and power wire from alternator to battery.
2/ upgrade main battery to faster discharge. The cars battery was never designed for this type of stuff, which is why there is a dedicated aftermarket for car audio batteries.
3/ upgrade alternator.
4/ add second battery (don't do this first even though I previously said that)
5/ add cap depending on type of music, and if you really need to do this, you most likely have not done something else properly.
Your system alone is pulling roughly 50 amps (how much you're actually using, I don't know). I don't think there is enough headroom on our alternator for that, thats why the faster you drive the faster the battery replenishes and is able to provide the reserve smoothly.
What works for one application does not necessarily work for another one. Motherboard does not equal car. What is the reason for a cap? To provide power for a depleted system. Why do MOST people, and what I would say is the original reason, people put caps in their car? To stop their lights from dimming from the amp draw. So then why put the cap on the amp instead of the lights? What the cap does is release its stored energy to supply the demand, then it recharges. Release...recharge...release...recharge...release...recharge. If you are playing the type of music that "needs" to be played loud, at what point does a cap actually have time to recharge after depletion? BOOM, BOOM, BOOM, BOOM, BOOM. Where is the quiet portion of that music to recharge? Because I'm sure he's not banging opera. You are still putting a strain on the alternator and battery with a cap. Remember the type of music that was running when caps were introduced to car audio, it's not the same as today...in production, engineering, or dynamics. Take a pale of water, cut a 3 inch hole at the bottom, and fill the pale with a 1 inch diameter hose. Whats eventually going to happen? That is your cap. A cap eventually becomes a bottleneck.
Remember, for the most part your battery is your cap when the car is running. So if your battery cant handle the load, how is a cap going to handle it? And remember you aren't even talking about dimming lights at this point. A cap for car audio IS a waste, and I stand by that.
I'm glad you asked me this to make me go through the motions, I can go ahead and fix my problem now.
Did you ever do the install? I am thinking of doing the same thing.bent99 wrote: ↑Thu Apr 06, 2017 4:18 pmSL33P3RM45
how did you wire up the JL stereo? I am interested in installing an aftermarket head unit where the cassette deck is in my 03. I plan just pushing the cassette up into the dash and modifying the existing whole / space to accommodate the new single din head unit.
