What wattage should you be expecting?

What wattage should you be expecting?

I'm sorry I"m so stupid i forgot to mention the watts.well the hifonics is rated at 1500 watts x 1 @ 1ohm but I heard it's over rated so I don't really know the real wattage it will be putting out.the JBL is rated 104 watts x 4 @ 4ohm

thanks in advance

Well what impedence/ohms will the sub amp be running at? I would assume 1, but we need to know for sure. Same with the JBL, are your speakers 4 ohm?

1 ohm on the hifonics 1500D and 4 ohm on the JBL

Hi, I have two Rockford p210d4 4 ohm subs hooked up bridged to a rockford p5002 amp. I tried this method, and my subs were crackling and making bad noises like zapping/ electrical sorta after I increased the gains until 44.7 v. The subs and amp are new, and before I had the gain on 0. This was also at a much lower volume than what I tested them at. I have an Eclipse cd4000 hu, and the volume was on 55 when I did the voltmeter gain setting, after when I hooked back up the subs, they were crackling on 45. I turned the gain back down until they sounded OK, which was from about 2/3 when I tested it back to about 1/3. I have the lp on 80, and everything on 0 except sub volume is the highest it can go. Bass boost is 1/4 or less. The subs are so quiet, you can barely hear them. Is that normal for these subs? Can someone help me out? This is the first time I installed an amplifier before, but I think I did everything OK. Sorry this is so long. //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif Thanks for any help you can offer

Make sure the non-fader is at 0 on the head unit.

Non-fader is like sub volume right? If I turn that to 0, will I be able to set the gain higher? Would I turn the gain up to where it was when I checked it with the voltmeter? Thanks for your help

Keep it to 0 while setting your gain, i listen to rap mainly so when i put in a rock/soft rock cd from time to time i turn it down to -2 or -3, however most of the time it stays at 0. And yes it the 'sub volume' or should be at least.
