Question about Cadence A7 HC Car Audio Amplifier

Diagnosis light I own a cadence A7 amp which is hooked up to two 12" kicker solo barics. Lately my amp has been turning on and off. Its not actually turning off but it stops delivering power to my subs and the red diagnosis light starts flashing. Im not sure exactly what the problem might be.

Re: Diagnosis light

It could be an overheating or power issue. It may be that the two speakers are loading it too much, which will cause it to overheat. Does the light eventually go off and the sound return ? Do you have the speakers wired in series or parallel ? What's the impedance of the speakers and the minimum continuous load for the amp ?

So I have the first kickers that came out the 15 will a 800 watt amp push um without eather blowin out

If you are referring to the Kicker L5 solo-baric subwoofer, then an 800 watt peak amp will not blow even one of those subs. The L5 is capable of handling 1000 watts peak and 500 wrms. An 800 watt peak amp will usually have around 400 wrms. Underpowering the subwoofer will not hurt the amp or the sub(s).

I hooked my Hifonics BXi 1610 Brutus series amplifier up to my 2 12" Kicker Solo Baric L7 subs. Everything turns on on the amp but its barely pushing my subs. Ive tried tuning it and it still doesn't push...

wire the subs if thair dual 4 ohm . in parallel. red to red and black to black. giving it a 2ohm load. do the other sub the same. and conect it on the amp . turn your gain about 12oclock and db level less than 12oclock and your frequnecy around 80-100. and that should work

Try any decent amp that runs 800-1000 watts RMS/continuous at 4ohms. Hifonics, Kicker, PPI, MTX etc. You should expect to pay $500+ for a decent amp. You get what you pay for.

Cadence A7 HC not working

If the amp is in protect mode, it probably has shorted output transistors. To eliminate other possible problems, read through the following page:

Amp in Protection - Troubleshooting

Let me know if you have any other questions.

Amp settings

It's going to be mainly "what sounds best", but I'll give you a start.
  • Set the gain to 50%.
  • Set the LP filter to 12db at about 80Hz.
  • Set the infrasonic filter to ON and at about 20Hz.
  • Set the Bass EQ to ON, Q to 0.7, center freq to 40Hz, and boost to about 5dB.
The other settings are going to be based on how the system is connected to the head unit.

500/1 v2 and one kicker VS12L7

It will work fine. This amp is stable to 1.5 Ohms, but is designed to put out about the same amount of power at 2 or 4 Ohms (unique).

Dont know whats wrong

You can check the fuses if it has more than one. Or another thing that might be wrong is that you might have to big of a speaker hooked up. Or your power wire might be to small because if its two small then the amp cant get enough power to power a big speaker.
