Bass not hitting

I have a hifonics Gen XI zues amp and a JVC headunit with subwoofer out and 2 15in kicker XPLs. as of yesterday the system was hitting hard as hell and today the bass is not the same it's hitting but not hard like it was, and I wasn't even running it hard yesterday. is there anyway to figure out if it is the amp, radio, or speakers. The radio is not under warranty and neither is the speakers but the amp is. Thanks

take an impedance reading on the subs.

Sounds like yu lost a speaker.  Are they in parallel?  Try hooking them up one at a time and see if one is gone.

Checked the ohms both are at around 3 ohms. I am not running my amp bridged I have each sub on it's own channel and the are single voice coils. they both work just not hitting hard like they were before.

It is probably your eardrums LOL :)

If it was just me I would agree but others have said the some thing(haha)

wow thay still make hifonics? i had a zeus about 10 years ago in one of my first systems

Yea my first one was about 10 years ago to and never had a problem and I have owned about 6 zues's since then

maybe a fried RCA?   maybe only running one channel of the amp?

Is it possible it is the caps I am using went bad. The reason I say that is that before this all started my lights never dimmed and and my alt guage never moved now the lights are dimming and the alt gauge moves a little when the bass hits?

If your battery/charging system aren't up to par, your amps'll never make their rated output.  Check that.  You wrote you checked the resistance.  Did you check this at the amp's terminals or at the speakers themselves?  Ensure those connections are nice and tight.  If they're in the same compartement (not seperately) it may appear that both are playing when only one is.  Check to make sure you didn't just turn off a setting or something, in the deck, or the amp.  You need to listen to the system under the same conditions as you did when it hit hard yesterday (same CD, track, etc.).

My ex once told me I have a perfect face for radio.

I checked the subs at the speaker not the amp with the amp disconnected. They are in seperate chambers in the box. I am going to take the radio out of my wife van and put it in my truck and see if it is better(want to make sure the sub section of my radio is not fried) I will post results either way. As far as the charging system, It worked perfectly up until the time the the bass went away that is why I thought it might be the caps because it happened so quick. Just a quick note I did hook my sub amp to the rear RCA outputs of my headunit and the bass was better but still not as strong(reason I am checking the radio)

Chech the charging system before you take anything apart, if you don't have the equiptment to do it your local auto parts chain should do it at no charge.  You'll probably find it is either not working or barely working, and it's a lot easier than removing and intalling the radio three times.

Charging system checked out good any other ideas?

Ok, I checked a couple of things My amp is clipping and cutting out with the volume up. It seems to me that the amp clips as the voltage drops a little but I was told that charging system is fine so am I am back the the same question is it possible that the caps are bad adn is there a way to check them to see if they are wroking correctly

Sounds like you're trying to draw too much current from the alternator which is causing the voltage drop, not the cap.  Do you have the proper gauge power and ground cables for your application?  Shut everything off.  Check the voltage at the battery, then at the cap.  Now turn on the system and crank the volume a good bit.  Measure again at the battery, then the cap.  As long as you don't have more than a few tenths of a voltage drop, your cap is probably fine.  If this is the case, upgrade your alternator.

Ok, At the battery I have app 12.6 volts same at the caps car off. with the car on I have app 14.2 and about 13 when the bass hits. I am using a 0/1 guage wire for ground and power

If yur amp is clipping you do not have your gains set properly.  This could be the entire problem.  Set your gains correctly.
