Re: Need to know the right setting to apply for my subs
You need to match your amp's input voltage (the gain) to the output voltage supplied via your deck's preouts. Turn you radio up to normal listening level, and turn the amp's gain until you induce audible distortion then back it off slightly. Set the bass boost and crossovers to on and type (highpass for front/rear full range or lowpass for subs).
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

Cut your gain back on the amp. It sounds like they are set too high. Check your install instructions on how to set your gain. If you have a 4 or 5 volt output head unit your will not be at half way. Im running a JL Audio 500 /1 on a skar wwv10 dvc in a ported box. My gain is set about half way & its plenty loud.I have a Alpine 9887 headunit 5 volt output on my RCAsI can take a volt meter & set my speaker output at 45amps & my gain in perfect.
Sounds like a bad rca connection. You need both rca jacks to be plugged in from your head unit, both left and right or you will not have full power you'll have half power to your sub/subs. Check your sub with a volt meter and see what it reads. Make sure if your head unit has a sub volume make sure it's turned up. Alot of people don't realize they have a seperate subwoofer volume on there deck and it's set to low, so check that. You could have bad rca cables. If all that is ruled out(best way by trying a different amp) the amp itself might be having problems. Don't think it would be in protect mode either. Let me know if you have'nt allready.
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.
i beleive they have to be the same amps.an i think they have to be able to handle being strapped together.id look into getting new amps to run it elemental deisgns i know u can strap them together an controll them from the master amp.i dont think alpines handle 3ohms that good either.im going to check a few things an see if u can strap them two amps toghter.if u need more help email me email@example.com
You need to have the amp bench tested at a car audio shop. Sounds like a dead short in the amp. Try turning the crossover on the sub "off" and connect any other speaker to it. if you have the same outcome, your amp needs serviced. Post a comment with your results and if I can think of anything else you could try beyond that I will. Hope this helps
this is the problem with the additional battery wiring. use appropriate cutout and do rewiring. make sure the Dynamo has the enough capacity to charge both the batteries. better avoid using your music system till the problem is rectified.
I dont know if this will help you but start at the deck and make sure that the outputs(RCA) arent crossed over to highpass and do the same at the amp make sure that its set for lowpass- set half gain -bass boost half gain- subsonic minimum - If that doesnt help try using an i pod with an adaptor that you can play it right into the amp this is to see if you are getting signal from the deck to the amp if it doesnt work with an i pod or mp3 plugged directly into it then you may have got you a blown amp going on- good luck with that
