[[EDGHIA]]

Hey guys i have recently purchased 3x 15" Soundstreem Picasso series subs.... they are 400RMS each and trying to think of the best way to amp them..... if i should run them off 1 mono block or 3??? wat would you do???
this is a seriouse thread aswell.... its not bull shiz

[dave.747]

Are they dual voice coil? 4 ohm, 2 ohm?

[ROOSTA]

How many voice coils and wat impedance (ohm) are they???

Cheers,
Nik

I would run one of the below combos..

2 x 15's wired to 1 ohm off 1 big mutha funkin d class..
2 x 15's wired to 2 ohm each off 2 d class mono blocks..
3 x 15's wired to 2 ohm each off 3 d class mono blocks..

Do you really need 3 x 15" subs in a falcon??? LOL..

Cheers,

3 is a ***** of a number of subs to run... I'd probably drop 1 or add another.. i dont think that you value boot space much.. with 4 then at least you can wire 2 in series and 2 in parallel and then get a nice 2 ohm final load on 1 massive mono..

what area you from? if i can help you with anything let me know..

[[EDGHIA]]

thanks for the info guys.... i think i will run 3 mono blocks..... and yes i need 3 15" :P it need s to be big and unique..... plus dont worry they will fit :evil3:

[ROOSTA]

I know theyn will fit.. i did an install of 8 x 12" subs in a falcon and before that it was 4 x 15"..

3 will fit without even trying.. LOL..

Cheers,
Nik

[xrtonv]

Well seeing that ppl are offering to help with instaling sound system anybody interested in helping me make a 15 inch sub box?? lol

yeah i would do 4 but i think it will break the dudbet on amps...... i dont really mind how much i spend but i dont wont it to drag out over a long time.... do you no if response do an amp that would suit thes subs good???

[ROOSTA]

I would personally go with 4 of the 15's and run them off 2 of the 1500wrms response d class mono's..

If you do decide to go with 3 subs.. 3 of the 800wrms response d class would do the job..

Retail price on the 1500wrms amps is $700 each.. and retail on the 800wrms is $400.. Cheaper if ya get a few at a time..

Cheers,
Nik

[-"Glowing" EF-]

or you can get 1200wrms clarion mono for $400

no clarion stuff is going in my car..... not a fan

[santoitaliano]

lol nah its just a bit to HeKtIc for me...... you see 4 subs in car all the time.... but not 3 15"......

[-"Glowing" EF-]

what you think of the latest MTX thunder amps, i heard they blow

[~EFhastE3~]

well in my opinion subwoofers are for chiks to go "oh my god... subwoofer!" im sure u'll make the right decision [EDGHIA] :

[ROOSTA]

How loud the system is is going to come down to enclosure design more than the equipment you use.. the old mentality of 25% equipment, 75% Installion comes to mind..

The problem with running 3 dual voice coil subs off one amp is that you will be presenting the amp with ~.6 or .7 ohms.. I have done this in the past and doesn't really give more noise but just decreases the amps efficiency and makes it heat up..

If you are looking at getting some response amps PM me when ya ready and i can hook you up with some good pricing..

Nik

stupid question.. why soundstream?

i like the stuff the make and have seen some pretty wicked stereos with soundstreem stuff..... and yeah :P pluss i want the big chrome spider grills for the boot install...

[ROOSTA]

I just did some research..

http://www.soundstream.com/subwoofers-picasso.htm

Nice looking sub but it is missing some important specs.. did the subs come with a spec sheet.. Does it have the xmax listed???

Cheers,
Nik

[ROOSTA]

I dont know wat the pricing is like but might be worth looking at there amps.. they have a couple of decently specced d class mono blocks..

http://www.soundstream.com/amplifiers-picasso.htm

Cheers,
Nik

[[EDGHIA]]

yeah they do but ther about $700 each :togo: ... so i wanna get something a bit cheaper

[ROOSTA]

The xmax is how much 'throw' the sub has.. that is how far it travels when pumping.. It is usually a critical factor in determining how well the sub will go and wat size enclosure to run it in..

Cheers,
Nik

[[EDGHIA]]

umm.... i dont no the answer to that but the guys who will be doing the install work with soundstream alot so it should be sweet.... :

[santoitaliano]

whos doing all the work...

chrome spider grilles are cool.. lol

roosta.. check out my subs mate.. www.jlaudio.com.. im running 2 x w3v3's... 12"...

3.0 cu.ft net vol.. facing into cabin.. kicker 750.1 pumping 465wrms into each.. i could prolly get a bit more out of them shifting the phase around 180 (eg into the boot), but i like the clarity and lack of boot rattle at the moment...

[ROOSTA]

Nice..

They look like a fairly tidy sub.. Plus coupled with a decent enclosure would give great noise..

Cheers,
Nik

Glenn, one quick question.
Why do you need to run 3 15" subs?

You can either Go Fast or Go Louder.............

Go Louder is alot safer and you wont loose your licence over it..........
