yes this is where capacitors have the upper hand, quick charge and discharge. however, for audio amps, batteries are quick enough. and temperature?additional batteries are usually housed inside the cabin.

4 gauge is fine and distro block unnecessary

buy a 4" port from psp-inc and run that. slot ports are no good, especially ones with bends in them.

lets answer a question. how large of a capacitor do we need to store the same amount of energy as a standard car battery? energy_cap= .5*capacitance*voltage^2 energy battery= amp-hour*voltage assume voltage across capacitor 12V, and use 80Ah and 12V for a car battery one car battery= 48,000...

this is completely wrong. it's the size of the capacitor that is the issue. a 1000 farad capicitor is worth something

half the port width when you split it. port length is measured along center of port

ya that's good. if you have lots of power then make it a little smaller

if space limited then why you jumping to higher order? just port that ****.

run a full ground, upgrade the wiring to the alternator, and then 1 aftermarket battery on the stock alternator should be fine. i used to run 2000 rms in explorers with only a group 74 yellowtop and stock alternator. if you wanna do more, do a second battery before a second alternator. and a...

why does this place **** so much for audio?

comparing two subs on paper (in terms of SPL output) is extremely difficult. i woulnd't pull anymore than 1000 watts.

what are you looking for? bass that gets low and can be heard from 2 blocks away? you're vehicle is a terrific platform for a system. however it won't thrive unless you've got enough cone area. personally i'd throw two of these in it: Alpine SWS 15D4 Car Audio 15" Dual 4 Ohm Type s Subwoofer...

well what you should do is plug three ports, so you have just one being active. then what you wanna do is study the air velocity. play a song with a lower frequency and turn it up and see how much air velocity there is. yes there are formulas to calculate the port area required, but that is just...

basically the load needs to be in series. so if each amp would see a 1 ohm load from a sub, when theyre strapped you want the pair of amps to see 2 ohms

Some of the paint ended up coming off. With really high humidity and time constraints we had to paint without giving ample time to let the primer dry. Bass knob, volt meter, and some switches: Rear wiring: Very happy with the overall look of the system. Turned out better than I had...
