Question about Legacy - American II: 2 Channel 2000W American II Series LA-1990 Car Audio Amplifier

1 Answer

Optimum sound performance needed

I have an american legacy 2400 bridgeable amp and two kenwood 1200 watt subs and and when i raise the volume of my head unit the bass don't sound as great as i would expect.
there is an adjustment lever on the amp with hpf and lpf (i think) and the main gain whats the ideal setting that my amp should be on and whats the ideal setting for the bass settings on my head unit as well.

Re: optimum sound performance needed

1) legacy products are highly overrated and i have never seen one put out the power it claims
2) if you are running the amp bridged, you need to match the impedance of the speakers to the amps highest output impedance, otherwise your system will not sound all that great...

what size fuse or fuses does your amp use? what size wire did you install with (power and ground)? did you connect direct to battery or did you connect to a fuse block or similar? did you use a stiffening capacitor? does it sound like it is clipping when you turn it up or is it just distorted? what kind of box are you using for the speakers (ported, vented, sealed, bandpass)?

if you give me the model number of your speakers and your amplifier i can probably help you more, but with the information you have provided, this is all i can offer..

hope it helps,

I have two 12 inch 1200 watt kenwood excelons and i want to bridge them to the amp but i can barely turn it up with out blowing fuses

Please check the impedance of those subs. Are they 4 or 8 ohm speakers? Do they have dual voice coils? this app may not be capable of handling dual voice coil four ohms and you're trying to bring it down to a 2 ohm mono.

I have 2 12in kenwoods and a 1200 watt pyrimade amp, how can i hook these up to be the loudest

1st have your subs facing inwards towards the front of the car, not facing out the boot, This creates a better bass.

Wire 1 sub to one channel and the other sub to the other channel.

Turn down your gain as low as possible and then power everything up.

turn volume to desired loudness and then start turning up the gain slowly, if distorts a little turn in back down a notch.

avoid using bass boost, I agree it sounds great but it puts more strain on your amp and shortens its life.

after sorting out your gain, tweak all others until sound is bassy and clear with no distortion.

If you would like to use bass boost, turn on bass boost first, then up your gain etc.

How well will a 1000 watt kenwood amp pump with 2 1200 watt suns

2 will push more air but be careful how they are wired so you dont go to low on the ohms your amp sees.That amp should be 2 ohm stable so read up on how to wire in series or parallel.

Wiring issues

Repeated blown subs

Unfortunately some of these speakers today... DO NOT PERFORM up to peak as they should.The on logical reason for this to be happening it that the speakers are NOT very DURABLE and cannot take constant playing. I would recommend to L7 the can take alot more abuse than your average speakers. Good luck and thanks for using FIX YA

Support Question about RMS

you are going to need an amp that can supply the right amount of rms power to make it sound good. these sony subs are rated for 380 watts rms. so in order to find an amp that will supply two, you must multiply that figure by two. so you will need an amp that can supply around 500 to 750 watts continuously (or rms). also you are going to want an amp that is either class d or class ab rated. these amps are built to push subwoofers exclusively and will give you the best efficiency and sound out of your subs. you will also want to get an amplifier is a monoblock amp, and not a stereo amplifier. make sure the amp can put out that rms rating at 2 ohms as two 4 ohm speakers equal 2 ohms wired in parallel. i have a kenwood kac9152d that puts out about 2000 watts max at 2 or 1 ohms (900 watts rms) that i used with my two sony xplod 10's for about 2 years. it was kick ***! now i dont know if you need that much power but they will handle it as long as you dont push them too hard for long periods of time, otherwise you might end up blowing them up! (depending on the box size that is, and the quality of it as well...)

i have years of car audio installation experience and can help with setting up and wiring any mobile entertainment system you can imagine. may i ask what kind of music you listen to and what kind of box do you have for these subwoofers?

if you have any questions email me at
