20 Most Recent Legend LA1490 - American Legacy Series 2 - 1400 Watt High Performance 2 Channel Amplifier Car Audio Amplifier Questions & Answers


I would definately say, in the world of amplifiers you usually get what you pay for. I would recommend getting a Memphis or MTX amplifier. Go to ebay, specifically search for memphis then in the search options make sure to put in mono or 1 channel. All memphis mono block amps are 2 ohms stable. In particularly I would recommend for you the PR series. it is the Power reference series and they are really boomy for the money. Anything that has the "ST" is getting a little old so I wouldn't recommend it but It still is a good amp, just not sure how long it would last and how badly it's been beaten in the past. Good luck. If you find an amp and are unsure let me know which one and I can help verify it for you.

Turn on stereo and use a test light to see if you have power at the remote turn on wire near the amp.

http://en.wikipedia.org/wiki/Root_mean_square
In mathematics, the root mean square (abbreviated RMS or rms), also known as the quadratic mean, is a statistical measure of the magnitude of a varying quantity. It is especially useful when variates are positive and negative, e.g., sinusoids.
However, the term "RMS power" is sometimes used in the audio industry as a synonym for "mean power" or "average power". For a discussion of audio power measurements and their shortcomings, see Audio power.

Pretty Straight Forward get a 8 or 4 gauge amp wiring kit.

Run your hot wire to the +12V from the battery make sure to install the supplied inline fuse near the battery don't connect to the battery until installation is complete.

Run the REM to your stereo power ant. Wire. if available.

Run the GND to Metal Chassis Ground keep it as short as possible.

Run the RCA Cable from the back of the Stereo to the RCA Inputs or Low Level on the amp.

This amp is 2 Ohm Stereo Stable which means you can connect 2 (4 ohm) speakers in parallel to each channel or 1 (4 ohm) speaker on each channel or you can connect 1 (4 ohm) Speaker in bridged mode.

There are other speaker configurations you could use but you cannot drop the load below 2 Ohm in stereo mode and no lower than 4 ohm in bridged mode.

Hope this helps

I looked up that amp, it doesn't have a listing for 2ohms x1 but it has 2 ohms x 2 and its at 250watts. For this situation, I would recommend a different amp or different subs. Right now you are getting the most you can get out of your sub/amp combo, if you only have single voice coil subs. Which is common in the mtx preloaded boxes. Either you want an mono block amp stable at 2 ohms or 2 dual 4 ohm voice coil subs. If you got the subs you would wire the voice coils in series so you could get 8 ohms then the subs in parallel so you could get 4 ohms, which would be the best for that particular amp. Good luck.

The most common reason for an amp (in good working order) to blow fuses is a speaker load that's impedance is too low. You may need to rewire your speakers.

Let me know if you have any other questions.

Usually it is necessary to remove the unit and disassemble it to free up a stuck CD for removal.
