sub and amp set up please folks.
 

Basically i have got a alpine HU with all functions nessercary, got some rainbow sl230 comps and a spl dynamics amp...

need now a sub and amp box wiring kit and a box

budget for all is £250 i would like around 400 rms

lastly the sub needs to be 12"

cheers guys :y:

Iv got my Diamond Audio M6 800wrms sub for sale for £90. and with the monie left you could get an amp to power it.

no thanks buddy.

:bump:

needs to be a 12" whys that?

Because that is what he is looking for.

oh haii jimmy-boy..

naa want a 12" mate, as i listen to dance and hip hop all time.

i listen to dnb and dance all the time and have a 10"

its more a misconception that 10"s can only produce a tight bass, and 12" boom

all depends on make and model

ive always been told that to within a certain extent that smaller diameter subs produce a tighter punchy bass and bigger diameter subs create a much deeper boomy bass? i listen to hip hop, rap, dnb and was advised to get a 12inch by loads of people. My mates 10inch sub cant handle some of the deep low bass in these genres nowhere near as well as mine! and there both very similar in spec and rms etc..

theres no replacement for displacement (bigger size = bigger bass)

thats just the general term though.. theres a LOT more too it than just that.. im pretty sure my soundstream t410 ran off my jbl.gto.1201.1 will hit a lot harder than my pioneer400wrms ran off my kenwood 2 channel amp. even though the pioneer is 2" bigger

box spec is a crucial factor too.. along with how the eq on the amp / HU is set up. or if you have a seperate paramatic equaliser within your system to adjust certain freqs

fair play does it also matter about ported/sealed boxes as well? i was told my sealed box will produce a deeper bass than my mates ported?

ash mate im pretty sure i want a 12" mate ;) lol

any chance you can find something maybe post a couple of links on 10"'s too

but pretty fixed on a 12 now lol... see what ya can do :) you no i'll buy it.

:bump:

:bump:

i have this, work's out at about £140 delivered.

car audio security where slow on the delivery (2 weeks) but well worth the wait.

looks good mate, do you no the wrms figures etc?

cheap aswell for what it is :)

check his vid out link i have not got a vid as i took mine apart to make a false floor. you obv want a better wireing kit tho.

yeah, i'd get a better wiring kit.. does seem good value for money i'll check out some reviews as that video looks insane lol.

looking at the figures the sub will be underpowered?

Sub:

- 350watts rms @ 4 ohms

Amp:

225watts rms @ 4 ohms

?

# 225 watts RMS x 1 channel at 4 ohms
# 360 watts RMS x 1 channel at 2 ohms & 14.4V supply

for that package ;)

oops too late lol

looks good on that video, am running 350rms from a alpine amp so a spl dynamics sub not much shaking lol but does sound good, had a JBL sub too a 1202d not bad either:)

this is a good package too apparently that box is very good the amp will underpower it tho .. http://caraudiosecurity.com/shop/pro...s_id/8336.html

just get a second hand amp off ebay i got mines 350rms for £55

don't think i'll go for the packages now.. never are that great like ashley p always says :P

so bump this up fo' shizzle.

the only way you will get a good setup is look at your budget, your amp will cost 3/4's of your total budget! so if you want to spend £250 look for an amp for about £150-£180 then find a sub that will run around your amp. packages are good because they are designed to work. they cut the whole looking for parts that match. imo an underpowered sub is better because ther is lees chance of blowing it!

why does the 12" make a difference tho

:bump:

i get told always have a more power amp than the subwoofer. i use a 1300watt 2 channel mono amp to power to vibe 1200watt slick subwoofers they both sound great as i am powering both subs with 1300watt,

your sub will be under powered but its better to be safe because it may distort and pop :) eventually ive done that many of times :D

Decent speakers can handle a lot more power than they are rated at. My components are only rated at 40wrms and i am running them of a rated 90wrms from my amp. As long as the signal is clean (distortion free), and the gains are set correctly then you will be quite unlucky to damage your speakers by overpowing them as you will have to do so by a lot of power.

You can also damage a speaker by underpowering them.

:bump: still looking

ive got a 1200wrms amp & sub set up which cost me £180 :), its all about where you look. and your wrong, as alex said in my quote below if set up properly the speakers will be fine, coonper ran a shitty set of 6x9s rated at 90wrms with 600wrms and they didnt blow! oh and in your statement of budgets, you forgot to include a box and wires

the general rule is: bigger sub, more bass, smaller sub, tighter bass.. this isnt allways the case though, as a 500wrms 8" sub will produce more bass than a 12" 50wrms sub.. however, theres no "replacement for displacement".. this is similar in terms of quality, allthough a smaller sub will have better quality than its bigger counterpart (providing same brand, same model just bigger size) this isnt allways true as a £500 12" will sound tigther than a £5 8", quality of parts used, and brands plays a huge part, you get what you pay for.

you dont understand how wrong you are :)

this is the only correct statement in the whole thread

finally, to jimmy:

sub:

amp:

wires:

few points:

1, youll need a box, i didnt reccomend a prefab box as theyre awful, ideally you should leave this stuff boxed up in your room while you save for a custopm built box, remember a box is more important than the sub

2, yes it is much more than the 400wrms you wanted, allthough i dont understand why you want a set rms wattage, and also, if its too bassy, you can turn the gain down (this will reduce the bass output, and wont damage your sub before any noob says it)

cheers mate will order asap, any recomendations on where to look on a box?

Lol, you cant damage speakers by 'underpowering' them, what do you think the volume knob does?...... reduces the power sent to the driver!

Damaging speakers by simply using a lower power amp only ever happens when the gains are set incorrectly causing clipping, the same will happen with a higher power amp.

thats what he meant by underpowering lol.. as in an amp with less rms than the sub

regardless of what power amp you have, failure to set the gain correctly and you have a melted VC on your hands :n:

Dont follow what you mean but using an amp with a lower rms power output than the subs rms rating still wont damage it.

thats our point?! lol

it was stated earlier!

someone said "you should underpower to avoid damage"

alex & my reply was "your wrong, if set correctly its ok"

youve just debated the point all over again lol!

i hav 2 diamond m3's n a Pheonix gold qx900.1 im lookin to sell.... sound niiice
