Re: 2000 watt jl audio amp & car battery...
Make sure that you don't have any strands that would connect the remote lead to the constant +12 volts. Also make sure that your remote lead fromt the radio switches off when you shut the car off. If you don't have an aftermarket radio with a remote turn-on lead, tap into the ignition wire to the radio. Let me know what kind of car you have and I can point you in the right direction to get the right wire. Good luck.

you dont want to connect both of those amplifiers together. You could run them separately to separate subs or the jl to your sub and your alpine to your front speakers. But you dont ever want to mix and match amps to the same sub. Even if you had 2 jl500/1's you wouldnt want to just hook them up together. Because they both have to be putting out the exact same amount of power. Which no 2 amps are ever exactly the same. Some companies make bridges to properly connect 2 exact amps together. I Hooked up 2 JL 1000/1's to each voice coil on a 13.5 W7 and i smoked the sub. So i definitely dont reccommend doing it unless the amps are conneccted to separate things.
Recomend installing a capacitor, this will control voltage drop and reduce heat. The new battery should help, but it also may be that the amps final circuts could be wearing out, and no longer able to handle the load of the sub.
JL W6's will perform well with from 150-600 watts RMS. W7's with from 150-500 watts. Less expensive Alpine Type R's work OK with from 200-500 watts RMS. Either of the brands will sound good. None of them will perform to their full potential with 300 watts RMS. Powering any sub with a 2-channel amp is a compromise. A monoblock is more efficient.
It is stable only to 1.5 ohms so your best choice would be the 15.4 with dual 4ohm voice coils. In parallel, this would offer a 2ohm impedance. The 15.2 could only be wired for either a 1ohm load (too low) or a 4ohm load (less power).
Well this is interesting, Let me start by saying if you have a 2 ohm load and your system is set for 4 ohms you are going to overdrive your load and burn up your amplifier, maybe not right away, but sooner or later it will fail due to electrical and thermal stress bought on by power dissipation issues.
Yes you can get 2000 watts out of your amps, but the correct way is to bridge your amplifiers if you can, and terminate them into the proper load.
hi, have you figured out whats wrong with ur amp ...i have the same amp ....and as soon as i finished the connections ...and connect the remote on wire,,, the amp goes on ...making a ticking sound with the green light blinking and the red light staying solid on ...whats the problem please help ....how can i fix this ......my amp is a jl e6450 ....im using a panasonic cd player with a built in amp ....and thats the cd player im trying to connect to the jl amp ...please HELP
