I need a manual for Boss AVA 650 Amplifier - Tascam Car Audio & Video

Manualsonline.com

High input is designed for using speaker level output from another component (such as an amplifier) into the equalizer. Any source that is loud enough to power a speaker is a candidate for that input. The other type of input is the line-level input. This is a more common way to connect components. The power level on these is very tiny and must be amplified in order to be head.

Yes you can use the equalizer without an amplifier. That is what the high level speaker inputs are for. You simply take the positive and negative from a speaker and hook it up to the positive and negative high level speaker inputs on the equalizer.

wires are: red-ignition, yellow-battery or memory, black-ground, blue-remote for amp or antenna, orange-illumination (if it has one), the white, grey, purple and green wires are the speakers

You need a 30 amp fuse according to Boss Audio's owners manual.

Well without seeing a spec sheet on the amp and not knowing your voice coil impedance I will assume the following. If the speaker is dual 4 ohm voice coil the in parallel it would present a 2 ohm impedance to the amp. If this amp is stable down to 2 ohms bridged then that would be the hookup of choice. If it is not stable to two ohms with one speaker it will be tough to get full performance out of your amp. You would have to series the voice coils which would then present an 8 ohm impedance to the amp. Just look at your amp's manual before making the decision. My suggestion would be to get another one of those subwoofers parallel the voice coils on each then wire the two subwoofers in series. This would give you a 4 ohm load which your amp is almost certain to be able to drive.

What info do you need? All amps are exactly the same and the manual only differs for specific specs and db ratings!!

ENGINE NOISE PLUG ALL YOUR RCA DIRECT TO AMP BYPASS EQ AND SEE WHAT HAPPEN IF THIS STILL HAPPEN CHECK ALL YOUR GROUND AND RCA MAKE SURE YOU HAVE GOOD CONNECTION

remote connection and the unit should work

Disconnect all the wires and make sure that their all connected to the right terminals. If not positively sure trace all wires back to source. If you ground and power is swapped it will automatically go over to protection mode.
