Help on Memphis Belle wiring - Buy & Sell Car Audio Equipment

**IonSQL** · 03-31-2007, 05:54 PM

So I finally got around to getting my new equipment installed, but I'm having some confusion with the amp... Memphis Belle 16-MC1300d (the chrome one)

Head unit is Sony XAV-A1 screen... wiring is as follows:

--Front HU preouts: single set of RCA's, left channel is split to channel A on the amp, and right channel is split to channel B on the amp

-- Rear HU preouts: none

-- Sub HU preout: single set of RCA's, combined at the amp for the mono sub input

-- Each channel on the amp is bridged and set for 150w per channel to a set of Crystal SSCS6

-- Sub channel is set for 1000w @ 1 ohm to (4) eD 9Kv.3's

Everything gets wired up, and I turn on the car. Wait for the bass to hit, and only hear the comps. Hmm... so I open the trunk, and nothing. Unhook the RCA from the sub channel at the amp, and voila, bass. Hook the RCA back in, and no bass.

HPF for the comps are set to ~100Hz at the amp, and LPF for the sub is at about 80Hz at the amp. SSF is turned off, filter selector is set to HPF.

I confirmed that the RCA's are hooked up to the correct inputs at the amp and outputs at the HU...

I'm lost... any ideas?

You need the stereo to mono converter that memphis makes for it to work properly

You're not talking about the bridging module, are you? I don't know anything about the mono converter???

Either way, I think I've got more going on with the amp. If I hook up the mono input, and wiggle it around a little bit, it activates, but receives the same signal as the front and rear is supposed to be getting i.e. words are coming out of my subs

I've got a SquareTrade warranty with the amp... guess I should give 'em a call, huh? :crap:

Ya the module.
Memphis did some weird ish with that amp, the RCA's are very very very fussy

that input only accepts a summed mono signal. You need a processor that puts that out or the module like supa said.

Let's get this fixed before Saturday Chris

So where can I find such a module? Know any place online that sells them?

I can't imagine that would explain why wiggling the sub input would play MUSIC though?????

Sounds like it would play music becuase it's not being converted to a MONO signal???

But only when I wiggle the RCA connection? Sounds like something shorting out somewhere to me....

I knew about the bridging module, but I thought that was for strapping 2 mono amps together? Is this the device I need though?
