[QUOTE="onobeka, post: 1079155, member: 562784"] I have one from the latest 7 series. It's the lowrange deh 3700 mp, but I might switch it to the 4700 soon. The only difference I can see between the 3700 and 4700 beside looks for what's interesting in sound quality is that the 4700 has the mosfet amplifier and a little more powerful. My midbasses are 4 ohms but If I will wire them in parallel that would be 2 ohms. The head-unit has only one preamp for the sub. But I don't want any amps so I was thinking about two bandpasses, one for each speaker and connect them to the rear outputs from the HU, so normal amplified/equalized full range freq from the HU in the bandpass enclosure with small mids. Of course first I was gonna try one enclosure [IMG]//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif[/IMG] to see if that works. [/QUOTE]
