Legend LA1490 - American Legacy Series 2 - 1400 Watt High Performance 2 Channel Amplifier Car Audio Amplifier Questions & Answers
Hey
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.

Whats rms on legacy la1490
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.

Legend Amp hook up manual.
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
Subs
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.

Wondering why im blowing fuses
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.

No sound from wireless headphones in a toyota sienna
First thing to do is check to make sure that the batteries are properly charged.
Second, make sure that you have a clear line-of-site to the IR transmitter. Infrared (IR) works the same way that your TVs remote control works - if the signal is blocked, then you will not hear any sound.
Third, make sure that you are in the rear seat of the vehicle when listening to the sound. The IR transmitter only transmits to the rear seat, so you will not hear any sound if you are sitting in the front seats. This is a common problem that i see.
Lastly, make sure that the heapdhones you purchased are compatible with your 2006 2007 2008 2009 or 2010 Toyota Sienna. Remember that some older models require RF headphones, not IR headphones. I checked http://www.audiovideo2go.com for compatibility before I purchased my headphones. They have a useful listing of all the headphones and models of vehicles they are compatible with.
