20 Most Recent Legacy - American II: 2 Channel 2000W American II Series LA-1990 Car Audio Amplifier Questions & Answers

Hopefully this helps

25 to 30 amp fuses will work great, anything lower could possibly blow a fuse when a good bass note hits even if there is nothing wrong with the amp. Hope this helps.

there is a slot in the amp for the one end of it it looks like a phone jack plug it in but the bass boost is asking your amp to create more power then it can so be careful with it

check you signal going to the amp and rca;;s

I would check the RCA preamp wires connecting the stereo to the amp. If these are loose or broken, it could cause you to lose your sound.

Does the amp show signs of life, such as clicking on, an LED turns on, or anything like that?

Has anything else changed between the time it worked and didn't work?

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,

4000 watt amp that was 2-channel with 2000 watts peak and 1000 watts RMS per channel, when wired as 4-ohm, which is what the sub's ratings are based on. therefore the amp and sub configuration were a perfect match, however approximately 1/2 an hour into driving with them i noticed a plastic/rubber burning smell and immediately shut off power to them. upon inspection both subs were blown and completely unusable. this leads to the conclusion that they were poorly rated and of poor quality materials, and i hereby advise that unless your going to run way under the limits, they are no good!

Good luck! I have been to their website and they dont appear to offer much. The manual is available that shows the pin out for the connectors but you are going to have to figure out what kind of connector is used by them and order it and then customize it with wires in order to use it. Most of their distributors are in the Jakarta region

It does look like there is minimal difference between the 1344 and your 3344. I would start your info gathering here LEGACY LMR1344 INSTRUCTION MANUAL Pdf Download ' ManualsLib I think the info you find here should be similar enough to get you started.

Is there a 20 or 30 amp fuse plugged in to the amp near where the 12 volt connection is? Usually, if an amp blows a fuse: something caused it. You must remove that cause, before you replace the fuse or it will just pop another one

250 watt per channel 1000 watt amp if so its a 20A fuse.

This Legacy LA 420 amplifier features 400 watts of power, two channels (bridgeable), a two-way crossover, Mosfet power, 2 ohms stable, and THD less than 0.04%. The amplifier measures 10" x 9.5" x 2.75".

Unfortunately, the amp is only 2 ohm stable, so the best option is to connect each subs voice coils in parallel (2 ohms) and connect the subs in series (4 ohms).

No, but you do need to have the REM connection from the amp connected to the remote turn on line of your head unit.

When woofers stop woofing it is because the voice coil is heavily damaged and stuck in the magnet air gaps or there is no amplifier power getting to the unit. Speaker connects need to be checked along with amp power to another known good speaker. If that unit also does not work then there is an amplifier issue that needs addressing.

if it really uses 1200 watts, that would call for a 140 amp fuse, which is outrageous. for that power, if turly approachable, you would need a v8 engine, and midified alternator(s) arrays, and a capacitor.
