sifu,

since i have decided the setup i'm going to do with full Alpine stuffs, with the mono amp MRV-M605 and 2-channel amp MRV-T420 to feed for the sub SWR-1242D and comp SPX-177R.

 

ok, now come to the connection problem. since i need to use hi-lo converter, i will use one converter to convert one a pair of full range speaker output to a pair of RCA pre-out signal, and connect this signal to the input of mono amp MRV-M605 that power the sub, then since this mono amp has a RCA pre-out, is it a good or correct way to use this mono amp's RCA pre-out to input signal to the 2-channel amp? or i need another hi-lo converter doing the same signal conversion way for the 2-channel?

If you r into SQ - I would suggest that u spend a litle more and add a pre-amp to your system.

Then the RCAs from the hi-lo would feed into the pre-amp, and from there you can feed into the 2-channel and mono-amp.

You would then be able to have some control over the sub volumes relative to your font spkrs, be able to set LPF for your sub, etc.

Otherwise, without the pre-amp, you would have to use splitter cables to split the RCA signals after the hi-lo to feed into your 2 amps - further degrading the sound quality which has already suffered from the hi-lo conversion. [pirate]

I am not familiar with the MRV-M605 features so not able to comment about the alternative RCA outs from the amp to feed the 2-channel.

kwongwing,

i'm think to use two hi-lo converter instead of one only, below is how i plan to do, i think still better to do with only one converter.

What you intend to do is a workable solution, as your amps have controls for crossover settings/filtering capability. With the fader control you would also be able to have limited "volume/gain" controls between your component front spkrs and the sub.

However, my personal preference would still be to install a pre-amp as earlier suggested. [nod]

bro, whats your ride? Civic FD? Why not consider add on separate HU? Then you won't need to bother with those hi-lo converters [:p]

bro, if you are serious about the SQ of your ICE, ditch the built-in HU.

 

The system that you proposed is capable of fantastic sound quality but with a built in HU and high-lo converter, I'm thinking you will probably get about max 60% of the system's full potential.

*sigh*

I probably sound like a broken record but I will keep saying this:

Imagine buying a nice KEF/Marantz/Arcam/B&W/Sonus Faber/JM Lab/Rotel/etc home amplifier and speaker combo, then you wire up your existing $100 mini-compo by tapping its SPEAKER output, go through a high-low converter, and then into your Marantz/rotel/arcam amplifier to drive your KEF/B&W/JM Lab speakers....

 

Doesn't make any sense, right?

 

Forget about speaker-level inputs in the amp, basically what it means is that the high-lo converter is built into the amp. To use a somewhat crude phrase: LPPL

 

If you really cannot give up steering wheel control, well, I have seen my installer hooked up an external upmarket HU with the OEM volume control of the steering wheel. It was a Clarion HX-D2 in a Mazda 3. So it is NOT impossible to get a aftermarket HU to work with OEM steering wheel volume control.

It's a limitation which Kelvin would have to live with as one of the condition / limitation which he was working with from the very start was not he would NOT be changing his HU.

I have also helped fix up a add-on HU for a RX-8 as the stock HU sounded really BAD [shakehead]

Also got a Clarion D2 - swee [nod]

But we do have a friend (Kermit) who managed to get an after-market Blaupunkt HU to work with his steering wheel controls - so there is still hope ... [flowerface]

yup, i am agree that with the setup i mentioned, couldn't get the best result in SQ, but i really have my own reasons not to touch the stock on-dash HU, if can why not i do it. Due to this, i'm scratching my head and my friend keep pin-point me the stupid idea i having now, waste money lar waste time lar...i know, but what i intend to do is, i wanna my ICE system be better than stock one, better SQ than stock, maybe my stock ICE only can score of 10 marks (or lower) in eyes of the ICERs, then now i'm trying my best doing the best from the worst condition, stock HU with hi-lo converter, wanna score for 50 marks, maybe?

 

got one ICE shop introduce this item to me, better than hi-lo converter, did anyone hear about it, how is its performance, worth the money spend? how much will it cost?

Audio Control products are generally of a high quality - the LC6i would in any case be better than any standard hi-lo converter, but may also cost quite a bit!

So your actual reason for keeping the stock HU is not REALLY about retaining the steering wheel control....

 

If you must have a hi-lo converter and want a high quality unit, besides audiocontrol, JL and Phoenix Gold (dunno whether still alive or not...) also make their own.
