Amplifier Connection... But No Preamp

[paddyboy15]

This is gonna take a while!!!

I'm Kinda stuck... I have a Sony CDX MP40 head unit for my 2001 Yaris T Sport. Details below...

* 23.2 Watts(RMS)/channel (4 Channels)

* Peak output 52W

* Compact Disc/Mini Disc changer controls

* Front & rear pre-amp outputs

* Wireless remote control (includes battery)

* NO SUBWOOFER PREAMP OUTPUT

* NO ANTI-SHOCK MEMORY

* NO DVD PLAYBACK

* NO VIDEO CONTROL

I also have an amplifier which will power a subwoofer, with midis and tweeters (which will run directly from the headunit), details below...

NOW...

I'm pretty sure i know how to wire everything, except one aspect.

The headunit has AUDIO OUT FRONT, AUDIO OUT REAR and BUS IN ports on the back. I dont know HOW or WHAT to connect the phono leads from the amplifier to on the head unit.

HOW DO I CONNECT MY AMPLIFIER TO THE HEADUNIT IN THE EASIEST, CHEAPEST WAY BUT WITHOUT A MAJOR LOSS IN SOUND QUALITY???

PLEASE HELP ME!!!

Are you just wanting to use the Amp just for the sub then, and want to continue to drive the main Speakers from the head unit?

In that case I think you can just connect one pair of the preouts to the MRD-M605 and it will resolve from that the Sub signal it needs. I think the rear connections would be the ones to use.

If that sounds OK for you then fine, but I would think you'd want to also ampilfy your other Speakers. Not sure if the MRD-M605 can power these and also drive the bass?

I know it does have preamp outputs for routing signal to another amplifier so you can feed a second Amp from this one if required.

cheers!!!! i think i'll give it Aygo (he he!) a go and c if it sounds ok. may end up running the components from a second amp but financially not viable at the mo!!

thanks again.
