If you have the RCA's running from the head unit to the amp, and the speaker wires running to the speakers then you have it hooked up right. Now If you still don't have any sound then you need to look at the amp to make sure that you have a green light. Still I would use 8 or 10 gauge power wire and then the same for the ground wire, make sure that you have a good ground.

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.

JL Amp isn't powering subs and speakers


silly as it sounds, you may want to check your EQ settings on your headunit. Things like sub volume, SLA, loudness and balance. When they replaced your battery, those old settings were lost.

Got jl300/2 amp confused which subwoofer sounds good


Hello drsubhakar26,

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.

Hope this helps.

Equipment not turning on!???


Have you tried checking the remote wire yet? Because it could very possibly be that. Without a remote wire hooked up, you cannot get any power. Try that and see if it works.

Have you determined if the problem is with the amplifier or the subwoofer?

 

Have you checked the wiring to make sure that there are no loose connections?
