How do I connect my RE-XXX 6.5's to the Orion HCCA 225G4?

[bdonkersgoed 10+ year member]

Hey Guys,

My Equipment:

- Alpine CDA-9835HU

- Focal Utopia 165W 2-Way Components in Front

- PPI Ax400 to power Utopias

- RE-XXX 6.5" Midbasses for rear doors

- Orion HCCA 225G4 to power XXXs

The Problem:

Now, my problem is this . . . how should I connect the RE-XXXs to the Orion HCCA 225G4? It is a cheater amp, so it likes to see a low impedance. The mids are 1.75ohms, so if I connect in stereo, the amp will only produce about 65W RMS, but the XXXs want to see 150W RMS. Is there a way to wire up the RE-XXXs in mono so that I get a larger output from the Orion, more suitable to the XXXs? The RE-XXXs are going to be the bass line of my car, because I will not be having any subs this time around. See the specs on the Orion and XXX below.

Here are the specs on the RE-XXX 6.5" Mids:

RE: 1.75 Ohms

Fs: 47.4 Hz

Qms: 2.33

Qes: 0.59

Qts: 0.473

Mms: 15.04 g

Cms: 7.505E-04

Vas: 21.49 ltr

1- way Xmax: 13mm linear

Le: 0.14mH

Bl: 3.636 t/m

Power: 150wrms

Spl: 87.75 dB 1W/1m

Here are the specs on the Orion HCCA 225G4:

4.0ohm stereo ~ 25W RMS

2.0ohm stereo ~ 50W RMS

1.0ohm stereo ~ 100W RMS

0.5ohm stereo ~ 200W RMS

4.0ohm mono ~ 100W RMS

2.0ohm mono ~ 200W RMS

1.0ohm mono ~ 400W RMS

Please help ASAP.

Thanks!

By the way, I am only concerned about the front sound stage. The Focals shoudl provide enough midbass, so I want the XXXs to provide as low frequencies as possible. Could I treat them like a subwoofer and run them in mono, and tune thm to low frequencies?

Thanks!

Well....yeah; but I wouldn't run them in mono and lowpass them any higher than ~80hz.

I dont know If I would really use them as subs. I've never tryed to play anything below 65hz on them, So I don't know how they would handle it...

Well, I guess I can have the installers play around with it for a bit. I can tune with my Alpine deck . . . what frequency range should I emphasize to the RE-XXXs?

Thanks,
