You use RCA output for amps. If you aren't running an amp, you don't need them. So go with the two or which ever one is cheaper.

Hi -

Sony CD player Red / White RCA - > CD input RCAs on the Arcam.

From the Arcam Preamp Output RCA's, go to the Bose "Input". From the Bose "Output", you need RCA splitters to make them into four outputs to run your amplifier connections.clmrt5000_2.jpgclmrt5000_3.jpg

Connecting a car stereo to an amplifier


you have to connect your 4 speakers to 4 speakers output direct to your car stereo no need of amplifier to 4 speaker but speakers should be small not like a woofer, and you have to connect your sub woofer by using amplifier don't connect direct. connect the output of your car stereo (using 2 RCA) to the 2 RCA inputs of amplifier. If u connect your 4 speakers to your amplifier then your car stereo does not support Left Right channel.
You can also connect your laptop or iPod direct to your amplifier.
Good Luck
enjoy music

I hooked up my JVC-KD-G210 and worked fine all of a sudden all 4 speakers quit the amp and sub still work i even ordered a new plug for back of stereo thought it was problem and still diddnt work id like...


Your internal amplifier for the radio has failed (output IC). Probably due to a shorted speaker or speaker wire.
Repairing the unit will cost as much as another one.
You may be able to pick up a small used 2 or 4 channel amplifier instead and use the RCA signal to feed it for less than the repair cost.
You will be surprised in the sound difference between a dedicated amplifier, and the one built in the radio anyway!
The typical radio SAYS 50Wx4... however - realistically can put out 12-15Wattsx4
a small 25x4 or 50x2 amplifier can be had easily for under $50 used, and will make a tremendous difference in sound quality... without having to spend more on the radio for it to potentially fail again anyway.
A Dedicated amplifier will have a built in protection circuit that will shut down instead of blow the output ICs like your radio did.

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

How much volts or ohms should be coming out of rca cables to my amp?


ohms does not make a difference for the rca cables, and the volts at the stereos max power will be whatever that brand and model is rated for the output cables, usually 2.5, 5, 7.5, or 9. your average output is for 2.5 volts on an affordable aftermarket radio

How to hook up a boston acoustic ba7500g speaker


you can connect the BA7500G speakers to a regular digital coaxial output by using a cable that has an RCA plug on one end and a stereo minijack on the other. However, the pole of the RCA must connect to the tip of the stereo minijack and the shield of the RCA must connect to the middle ring on the stereo minijack. Also set your soundcard to output at 16bit and 48khz.

Still no sub woofer output


SET THE CROSSOVER TO "L.P.F."POSITION AND SELECT THE LOWEST FREQUENCY AS THE CROSSOVER POINT.
[AN AMPLIFIER IS SUPPOSED TO "AMPLIFY"(TO INCREASE)ANY OUTPUT.]

TRY CHANGING THE POLARITY OF WIRES FROM AMPLIFIER TO SPEAKERS /SUBWOOFER.{it leads to cancellation of bass output.}
if u still have doubt contact me again.
