Would this amp work for my Kicker 12' DVC 4 ohm subs?

Question

My sub info:

# Power Handling (RMS): 800 Watts

# Power Handling (MAX) : 1600 Watts

Amp Info:

POWER ACOUSTIK LFA2-1800 2-Channel 1800W

2-ohms stable stereo

# Maximum Power : 1800 Watts

# RMS Power Output @ 4 Ohms : 300 Watts x 2-Channel

# RMS Power Output @ 2 Ohms : 380 Watts x 2-Channel

# Bridged Power : 760 Watts x 1-Channel

I got 2 Kicker 12' DVC 4 ohm subs and I'm wondering if this amp would be good for it. If not can you please recommend one that would be! I would appreciate it very much.

Answer 1

NO

when it comes to car audio nine times out of ten you get what you pay for- and you need to look for CEA-compliant brands which means that the amps have been tested and produce or exceed the advertised RMS wattage with minimum distortion (distortion is the main cause of speaker damage over time)

here are the top CEA-compliant brands

Alpine

Bazooka

Blaupunkt

Clarion

Eclipse

Infinity

JBL

JL Audio

JVC

Kenwood

Kicker

MTX

Pioneerdon'tolk Audio

PPI

Rockford Fosgate

Sony

since you dont know the real RMS wattage from that amp you cant properly match them up and if you send too much power to your sub, you risk damaging it. The cone of the speaker and the mechanical parts that make it move may break under the stress. Surprisingly, too little power can also damage your subwoofer — in fact, it's actually more common than damage caused by overpowering.

When the volume is turned up and the amp doesn't have enough power, the signal becomes distorted, or "clipped." This distorted signal can cause parts of the speaker to overheat, warp and melt. Not good!

You don't have to match speaker and amp wattages exactly. An amp with a higher output than the speaker's rating won't necessarily damage the speaker — just turn the amp down a bit if you hear distortion from the sub and don't run the speaker at extremely loud volumes for lengthy periods. Likewise, you'll be OK with a lower powered amp if you keep the volume down and don't feed a distorted signal to the sub

you would be lucky to get half of the advertised RMS wattage and it would more than likely be distorted from a lack of wattage

you will send the amp into clipping

Clipping

Clipping occurs when an amplifier is asked to deliver more current to a speaker than the amp is capable of doing. When an amplifier clips, it literally cuts off the tops and bottoms of the musical waveforms that it's trying to reproduce, thus the term. This introduces a huge amount of distortion into the output signal. Clipping can be heard as a crunching sound on musical peaks.

that causes distorted sound which will damage your subs

Answer 2

is it just one sub if it is then yeah it will push like 1200 rms watts bridged at 4 ohms
