ok so i have a 200 watt reciever now and i want more watts. so i bought a 650 watt amp i think it is anyway... but how do you hook the two together if it is possible.?? also how do you power the amp??? thanks for the time.!!!!!!
If your receiver has pre-outs, you send the signal to a power amp from the preamp outs. The power amp is powered by plugging it into a wall outlet, or car battery, if applicable. The connection from receiver is achieved with rca jacks and an interconnect cable. The speakers are then connected to the power amp.
Not that it matters, but 20yrs ago, Carver made a coupler, the name I have forgotten. From low powered amp speaker outs, to coupler, to new amp via RCA. I have no idea how or how well it worked. Simple impedance device, I suspect, but no details.
In case you are considering the idea of using your receivers speaker level output to your amp DON'T!!! It is a sure fire way to "let the smoke out of" the amp!
Your new amp can only handle line level input from the preout on the receiver.
what kinds of recievers have preamp outputs. do the prices run fairly low? and you can only hook sub woofers up to an amp? you cant hook up any floor speakers up too it?
OK sorry, my question wasn't very good. What is with the subwoofers? Are they car audio too?
Does your home receiver have surrounds sound (5.1 audio)?
If so, on both counts, it might be fun (but probably not what anyone could consider high quality) to use the receiver as is with the main speakers, use the receivers subwoofer out to the car amp to power the subwoofers. Powing the car amp gets rather interesting and can be done in a variety of ways but the best is to purchase a power supply (120V AC to 15V DC) of sufficient wattage to handle the amp.
Only trouble w/car amps in-house is that 650 watts of 13v is 50amps. Factor in 60% efficiency of amp and power conversion and that 650 output could go to 1500 watts from the wall. A 60 amp/hour battery wouldn't last an hour before voltage dropped too low to be useful and a recharge was needed.
You either need a bank of deep cycle / marine batteries or a power supply from a Lincoln Welder.
Car stereo guys use huge, low gauge wire, 4ga, and larger to wire power. Generally not available on a computer PS. I've not yet looked, but a 650 watt computer power supply will not put all that power to the 12v rail. There will be 5v and 3.3v A computer PS will be the total available on all rails, at max.
But by all means, give it a try and let us know. If it doesn't work to plan, you'll be a PS ahead, when you build your next computer.
