I need help :(

Help !

I recently bought a Kenwood Amplifier '' Kenwood KAC-7204 ''.

•2-Channel Class AB Car Amplifier

•RMS Power Rating:

◦4 ohms: 170 watts x 2 chan.

◦2 ohms: 250 watts x 2 chan.

◦Bridged, 4 ohms: 500 watts x 1 chan.

•Max power output: 500 watts x 2 chan.

•MOSFET power supply

•LED power indicator

•Tuned Bass EQ (0-18 dB bass boost at 40 Hz)

•Bridgeable operation

•Speaker-level inputs with signal sensing for automatic turn-on)

•Preamp RCA outputs

•Short circuit, DC offset, overload, and thermal protection circuitry

•Aluminum die cast heat sink

•Built-in cooling fan

•Gold-plated RCA level inputs

•Gold-plated screw terminals

•Variable high-pass filter (50-200 Hz, 12 dB/octave)

•Variable low-pass filter (50-200 Hz, 24 dB/octave)

•CEA-2006 compliant amplifier

•Frequency response: 5-50000 Hz

And I bought two 12'' Blaupunkt THW1200

Power Handling: 600W max/200W RMS

Frequency Response: 20-200 Hz

Sensitivity: 90 dB (2.83V/1m) - 87 dB (1W/1m)

Thiele/Small parameters: fs = 25 Hz, Qts = 0.50, Vas = 4.0 ft3

Impedance: 4 Ohms system impedance

Woofer Magnet: 40 oz. Barium Ferrite

Spring Loaded Binding Post Connectors

I also has a Stinger 2 Farad Capacitor.

How do I set up the frequency, Bass Bost and sensivity on the amplifier ?

And do I need a bigger capacitor, cuz my lights dim a lot.

Everything is well connected, it has been connected by an electrician.

I am desperate //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

get a agm battery for the rear (not a wet cell) to get rid of headlight dimming, and just as a generaliztion the amp freq should be around 50 hertz and bass boost is up to you if your expecting to shake the block you need bigger woofers amps boxes electrical wires etc...

You don't set sensitivity, no bass boost, and you can use the cap for target practice. What's your electrical like?

What do you drive to have 500 watts causing your lights to dim?

 

[toquet]

Only those two 12'' subwoofers....

What car do you have, how many amps is your alternator, how many batteries do you have?

 

[toquet]

I'm driving a 1996 Toyota Corolla. I have one batterie, and the alternator is around 70-75 amp.

Do not touch the Bass Boost on your amplifier.

As far as the capacitor goes, you could probably use it as a rolling pin in your kitchen.

If your lights are seriously dimming @ 500w to the point where you can't bear to leave it alone, the Big 3 should take care of that problem. Especially with how many watts you're running.

Not sure about Toyotas but check to see if they have an ELD (Hondas do). If they do, that will need to be remedied or nothing is going to help too much. But definitely do the big 3 and get the biggest AGM battery that will fit under your hood.
