Running 2 Amps of Stock Bluapunkt

[Weekend Warrior]

Hey guys,

well im doing research for my stereo install and this is what i have come up with so far

Sub Amp
Jaycar Response 1000WRMS Linkable Car Monoblock Amplifier

Speaker’s amp
Jaycar Response AA-0426 Car Amp 4x100WRMS

Sub
Alpine Type "R" SWR-1222D 12" 1500w 500WRMS

Front Speakers
SPL dynamics 6.5” HF-6.1 100WRMS each + EXT 1.0T 50WRMS splits

Rear Speakers
Don’t know yet…maybe Jaycar Kevlar response 6.5”

with this system im planning on running a black six stacker unit out of a SS which i will get Phreddy to do the Low level out put mod too (Blaupunkt low-level outputs? You betcha! :D) as well as the aux in mod too.

My question is though, will this mod give me enough RCA cables to connect up the front + rear speakers + the sub?

Thanks

[acarmody]

Phreddy mentions in this mod that he can do a 4-channel version too. So what you want is for him to do 4-channels for the speakers amp, then use the AA-0426s RCA output to connect up to the mono amp. Simple and neat.

[Weekend Warrior]

ok thanks for that mate, im a total noob with sound sytems so you'll have to forgive me hahaha

so it should look like this?


obviously with power and ground cables running from each amp as well.

Is there any disadvantage from doing it this way?

[Weekend Warrior]

if anyone could help it would be great...

[Philthy]

That diagram looks about right, except that there will probably be 2 sets of rcas coming from the headunit to the 4ch amp.

[Weekend Warrior]

oh ok, so one for the front speakers and one for the rear? thanks for that mate, helps alot. Also whats the best RCA wire you can get and where from? Trying to do it once and hence properly hahaha

[acarmody]

No need to go out and get the best RCAs on the market. I have Cadence, Stinger and Sony RCAs in my car and all work fine. But if you want some good gear then the Stinger Level 2(?, the second top level) gear is pretty damn good, don't get thier high end RCAs because they are very damn expensive. I believe the Cadence RCA cables are moderately priced and very good.

[Weekend Warrior]

ok thanks for that mate, i take it you can pic kit from local car audio places p/m? will they come with the connection ends on them or will i need to put them on myself? Thanks

word of advice, new response gear = sh!t

I spent $600 on a 5 channel amp, it wound up being a paper weight.

I had issues with it, it had noise and the 5th channel wouldnt run the sub. I was told the noise was because of phreddies modification, we installed it into a car with Alpine head unit ... same thing.

Jaycar technical confirmed "its overheating". When it come back the manager set it up in store and confirmed the overheating the technical guys found was true.

Can i have a replacement? No, it might be overheating but technically theres nothing wrong with it. Can I have a refund on the basis it doesnt do what I want it too? No, because you may have damaged it during your install. Now this is a store issue, but still, the product was faulty.

I was going to take it further but I had gone in and out of having audio, try hour and a half peak hour drive with no music for 4 days, so I was over it.

Whacked it on ebay, someone bought it for $150.

Then they complained, and sent me a copy of a technical report that said its been damaged caused by overheating (caused glue to run), only 3 channels worked and those that were working gave different output readings.

While this is going on the Response speakers started to play up one by one.

Not impressed. Im no expert either but those that know audio have also been saying its gone downhill, its no longer affordable decent audio, its cheap sh!t.

Just a word of advise from someone who poured money into his car only to have to revert back to standard for the moment ...

[Weekend Warrior]

hmmmm ok mate thanks heaps for this, really appreciate it. What was the exact model amp you had?


The reason im looking to go response is that i've had alot of people say good stuff about them and i heard my mate Chris' system with those amps on the weekend and it ****en pumps! And he swears by them, i think the ones i want have been on the market for a little while now though?

And yeah im probably not going to go jaycar splits for the rear now, thinking about a 2nd hand set of something a bit more upmarket

[acarmody]

If it was me I would turf the rear speakers and invest the extra money into the front speakers. This is where you sit and where you get your music from. A really good set of fronts will sound way way better then 2 sets of decent speakers and while you have named some really good speakers for the front, you could go exceptional speakers, or even a 3-way setup for awesome music, like maybe Focals 3-way system, would require custom install but would totally be worth it. Then you could bridge the 4-channel and pump all that power into the front speakers.

[Weekend Warrior]

yeah you have a very valid point mate...some thing definatley worth thinking about, but only thing is if i am carrying passengers i would like them to be able to hear it as well instead of just base from the sub.


Does this look like a good way to wire it up for my wagon as well?

[Weekend Warrior]

oh and forgive the dodgy photoshop skills as well, it's probably pretty hard to follow!

Yeah that looks good (except you forgot the remote wire)

I've been in cars with amps under the front seats and unless they are installed well they can be annoying for back seat passengers and might end up getting kicked a bit.
Nothing else is standing out that won't work though

EDIT: Oh, and I'm not sure the distro block will fit under the seat either but thats no big deal

[Weekend Warrior]

hahaha yeah im not sure what to do about the remote wire as of yet because it's the stock blaupunkt i don't think it will have a socket to put the wire connection in, any advise as far as this goes?

and yeah it will be close call with under the seat, but i had a look today and the bottom of the removable part is all just that yellow foam stuff so i can always just cut a square of that out so the dist. block fits.

[VZ-Rob]

I use the active lead from the back of the cig lighter in the console as the trigger wire
also added an illuminated kill switch for the amp into the console

hahaha yeah im not sure what to do about the remote wire as of yet because it's the stock blaupunkt i don't think it will have a socket to put the wire connection in, any advise as far as this goes?......

[Weekend Warrior]

thanks mate, so just run a wire from the back of the cig lighter to the remote witre port on the amp?

[acarmody]

Looks good mate, though I personally would put the 4-channel amp in the boot area. Under a seat can be complicated and annoying but still feasible, just make sure it has enough air-flow or it could overheat. Again 'personally' I'd just bolt them to the back seat, unless you fold the back seat down often.

I have my distibution block underneath my back seat without any problems but I don't know how a VZ wagon seat is clipped in so up to you.

And if you have a really good set of front door speakers you don't have to worry about the passenger not getting any music. Not only will they hear it fine but so will cars 3 lanes over, but hey its up to you. I'm a bit of a hypocrite because I actually have front and rear door speakers and 99% of the time I'm by myself in the car, and I never have any problems with sound stages or anything.

[Weekend Warrior]

yeah when i designed the system the main things i kept in mind was for it to look completely stock (amp under seat, factory speaker grills and cargo blind to hide subs) and also wanted to still have full use of the cargo area with seats folded down because i sometimes sleep in my car after a few to many beverages haha, so only place i can really see is to put the mono on the side of the sub box and the 4 channel under the passenger seat.


And if i was to just run front speakers, what would you suggest?

[acarmody]

Haha your car is a 'sleeper' in all definitions. Have you gone down and talked to the guys at Northfield Moorooka, they are considered very good and they carry a lot of top brands. If you had the money I would go with the Focal 3-way setup, but try these guys as they have all the good speakers on thier walls.

[holdenboy]

The SPL Dynamics fronts are a decent set, but they are designed to be ran "active" (no crossovers to split the sound frequencies up), not something you could probably do considering your using the stock h/u. Most active setups use a decent head-unit thats designed to run the fronts active.

I know i preach alot about the SPL Dynamics gear, and its for good reason. But in this situation its just not possible without a very high quality amplifier with the required filters / crossovers. There will be an option for passive crossovers soon, but not for a while yet.

Maybe look into the Focal 3 ways like acarmody suggested, but i would be going into the store and listening to as many splits as possible within your price range to gain a better idea of how each set sounds to you.

[VZ-Rob]

Yep! becomes active when you turn the the key to accessory
also stays live when you turn the motor off
and turns itself off when you get out and shut the door (Bonus)
So you can still listen in without starting the motor

thanks mate, so just run a wire from the back of the cig lighter to the remote witre port on the amp?

Thanks you so much for that info!!! Probably just saved me ALOT of money considering i was most likely going to buy the SPL's.

Three way focal, roughly how much and what model would you suggest? And it will be fully compatible with my headunit and amp choice? (considering 3 ways are usually awesome i'd probably just run the front two speakers and no rears)

[TMM]

Phreddy's mod provides a remote wire that turns on/off with the headunit

165VR3 $869 (AUS)
6.5" woofer & 4" midrange 3-way component set
Maximum power 160W
Nominal power 80W

Frequency response (+/-3dB) 55Hz - 28kHz
Nom. impedance 4 ohms
Tweeter TNB inverted dome
Mounting depth (midrange) 40mm
Mounting depth (woofer) 68mm

This 3-way set is only rated at 80wrms, but being Focal I'm sure it will take 150wrms without missing a beat, but other experts are better equipted to answer that.

But if you have way to much money:

165KRX3 $1649 (AUS)
6.5" 3-way component speaker set
Maximum power 200W
Nominal power 100W
Sensitivity (2.83 V/1m) 93dB

The champion of Focal's 3-way range without spending MASSIVE money on thier Utopia range.

Like I said go talk to Northfield Moorooka, they have massive walls of all the top and mid priced gear, well worth it. Complete Car Sound at Enoggera is another store to visit, not a huge range with high-end gear but good to talk too. Talking to the experts is the best way to ensure you spend he money getting the results you want, we can give you advice here on the forums but we can only help so much. What seems good or bad for us may be totally different to you, and speakers that sound great to us may not sound so great for you. I'm not telling you to keep asking questions here, hell ask all you want and we will be happy to answer, but ultimately a visit to a top-notch car audio shop will give you a much better idea as to what you want/need.
