I have a question about subs and amps. I am currently running all of my speakers and a 10" sub off of a 5 channel amp. I want to upgrade my stereo set-up in the trunk area.
What I want to do is shown below. I want to bridge my 5 channel amps sub channel to a mono amp. How would I do this in the diagram below. I have to buy another sub and a mono amp. What wattage mono amp do you guys recommend? Also, How do you hook up 2 subs to one output? Just use a "Y" adapter?

BTW...I currently have a 10" diamond audio thin mount sub and will buy another one.

 

dont know abot your question but what kind of diamond 10" are you running...you said you were buying another, i am about to sell my MKII 10" and go with the new 12" D9 series (400 friggin bucks each..jeez) Bama350zM.D.

 

DS10D2
It's a thin mount so I could fit it in my trunk. Roadster is hard to get audio in without removing the spare, which is what I originally wanted.

 

If I understand what you want to do, I dont think that it is a good idea. My rational being that the amps will never produce exactly the same signal to the subs, that is they will be + or - 25-45 degrees off in phasing. This, as I understand, is due to the misalignment of the power supplies within the amps.(switching power supplies)

Ditch the 5th channel and buy a larger mono amp.


*edit* looked at you diagram again

for the same reasons above, not a good idea. If the amp was 'strappable'(sp?) than sure, go for it. Only big monoblocks(and highend full range amps) are 'strappable.'

 

So I could't just put the line out of my 5th channel into the line in of my mono? Damn!
I guess if I have to just waste the 5th channel it won't be a huge loss. Adding a good mono can't be more than a few hundred right? I mean, my 5 ch. was only like 450. What wattage amp should I get to power 2 10" diamond DS10D2 subs?

 

Also, how do you attach 2 subs to one amp output? "Y" cable or is there another way. I have heard of running them in series. Is that better?

 

Line in? wait, Im confused now. Line in, like hi level in?


Diamond's site is down or my connection hates it but I can not get any specs on that sub via google or any other practical means.

So without that I cant make a suggestion.

You would want to stay with eclipse I assume?

 

I don't care about a different brand. Depends on what I can get. I think I'd rather stick with a local retailer so I don't have to pay shipping. I know a place I can get a good deal.
Below are the specs of the sub.

Model # DS10D2/DS10D4
Shallow mounting depth. Ideal for trucks and under seats.

Type: Dual voice coil
Size: 10 in.
Power Handling NOM/MAX: 200/400 watts
Sensitivity (2.83V/1m): 87 dB SPL
Freq. Response: 30-250
Mounting Depth/Diameter: 4.8 in. / 9.3 in.


I don't know what I meant by line in. Like...the RCA from the head unit to the 5 ch. amp. for the sub. channel. Then the amp has an RCA out to the sub. And the mono amp has an RCA in. So couldn't I just take the RCA out from the 5ch and feed it into the RCA input on a mono amp? Or could I get a lower power mono amp and run one sub off the mono and one off the 5ch.

 

If your 5ch has preamp input and output then you can daisy chain from your 5ch to a mono amp.

As for your cost of mono amp question, a good mono block amp probobly won't be cheap, a JL 250/1 would power your subs, but they would be underpowered, that costs around $400 new generaly, go with the 500/1 and your talking more like $700 I believe. But these are very good amps in my opinion.

As for how to attach them, this depends on how you want to run your subs, series or parallel, but the mono blocks that I have seen/used (JLs) have the hookups for 2 subs (2 + and 2 - connections) its just one channel, no left and right.

 

What about bridging a 2 channel or a 4 channel. I can get my hands on a 2 channel amp that was taken out of another car.

 

Bridging the 2 channel should work fine.

 

phoenix gold xenon 400.1 can be picked for about 300-400 bucks


and the 2 channel will work fine

 

1 more quick question. The max power handling of one of these subs is 400W. If I connect 2 of these subs to a 400w amp. does that mean each one is only getting 200w? Or do they both get a full 400?

 

Each one would be getting 200w.

 

Ok, I'll probably be looking at a 600w amp then.

 

I wouldn't look at the peak wattage of amp, go by RMS, much more accurate, many amp out there will say 1000w, but only be 200w RMS.

 

But if the peak power goes above what my SUB is rated for can't I blow it?

 

You could, but probobly won't unless your really cranking up some stuff with heavy bass, blown speakers is generaly caused by unclean power, not too much, I have blown subs that were underpowered.
