well, im getting around to building a system for my mini now, now that all the suspension work is done on the car and im going for mot next week i hope

anyways, i just ordered the start of my system
im going with this deck
http://www.kenwoodus...eivers/KDC-X693
because it has 3-4volt pre-outs and a aux input and a ipod input and plays mp3 discs also
i just ordered this deck and it should be here in a few days

and i ordered
http://www.kenwoodus...akers/KFC-1062S
im gonna build some pods to go up in the dash

and a month ago i got a small 160watt jbl amp off the forum for 30 pounds

and i have a old skool audiomobile mass 2012 sub
here is what the sub looks like
http://www.facstaff....movies/sub.html

the sub is gonna be underpowered but it will be ok because mini's don't
need alot of power to get loud and im gonna stick the sub
in a 3cube ported box so that will also help with the small power i have to give
it for now and im gonna build the box myself

the sub amp is for temp use for now, until i get my electrical system up to par
to run some sundown audio amps, i have the battery power but not the alt power for now

in sept or oct im gonna do my saturn alt swap
and swap out the mass sub for another one thats been built up to handle higher power

but so far i have about 120pounds into my system not counting the sub that i have had for many years


my goal for the mini is to do 145db's on music for less then 1000pounds

I'd rather aim to have high quality music that a stupidly loud max volume...

Kenwood HUs are crap by the way. Stick to Alpine or Pioneer.

My kenwood HU is rather nice thanks. Got a kenwood becuase the bluetooth was much eaiser to use than in the alpine I wanted (from reviews I read).

Bluetooth HU and high quality, best to go for is the Sony BT range. I've had both the 2600 and the 3600-U and they both worked really well.

pioneer or alpine h/u's wouldn't be my 1st choice for a high quality system,
and a mini isn't even close to a vehicle for a high quality system
so in saying that, im gonna say u don't know much about high quality system's
or havn't truly heard a true sq system

but for daily driving systems, alpine does make nice h/u's, ive used them
and like them

and the pioneers aren't bad, until the pre-outs burn up the input stage
on your amps because the rca cables aren't wired right, or should i say
the wrong rca cables are used in the 1st place
and if you don't know what im talking about them you should read up
on some real hardcore car audio forums
so no thank you on pioneer h/u's

but for me, ive always been a kenwood deck guy

look up the term sql

im building my system for sql, it will have the punchy bass to keep up with fast
kick drums of punk music and the low's to keep up with hip hop

also look up the company tc sounds, one of the greatest speaker making companies out their

my last vehicle was a truck with 2-18's hitting high 160's
and doing 155plus on music and it hit clean and clear also

I think you'll find it's SPL (sound pressure level). I'm certainly not a retard when it comes to this stuff like you may think I am.

Why are you aiming to hit 160 db anyway? That's just ridiculous - and you can't tell me a system hitting that level will sounds as good as a system geared towards listening at a "normal" volume.

the same reason why people want 1330 engines, when a 850 or a 998 will get you from point A to point B just fine

a system that can get loud doesn't mean you go listing to it at max volume everytime you listen to it
and a stereo like that at what you call a "normal volume" has alot of headroom at lower volumes,
and if the box is tuned in the low 30's, that will give you nice sql if the box is set up right for the sub(s)

plus music above 150 sounds the same to the ear

and im not talking about spl, im talking about sql= a mix of spl and sq, aka
really loud and clean hitting bass

starts out with a nice sub and a box design and built right for the sub specs

Underpowering the sub is a bad idea, the clipping and distortion will probably kill your sub, just so y'know (or so ive heard)

[westpark15]

hey
looks good but to be honest i wudda been aiming for pioneer as is such a better quality and also has the power there aswell and could definatly get it for under a 1000

[joakwin]

nope, under powering has no effect on your speakers/subs

as long as the signal is clean it doesn't matter
clipping is what kills the speakers, a sound wave is round and when you clip the signal you send a sqaure
signal, the signal is square because its beyond the limits of the range

you can clip a signal no matter what the amp is, if its over or under powered, it doesn't matter,
distortion is also caused by overdriving or turning up the volume to much
thats why to i set my gains on the amps with my fluke meter
and know the limits of the system

killing speakers by clipping is from trying to get more volume out of the system

[Jimmy Hat]

Fair enough, thought someone might correct me there, I remember reading that underpowering kills more subs than overpowering but then i also read that backpressure in your exhaust doesn't matter and that the bigger the exhaust the better performance you get...

[Ouster]

As joakwin, it only matters what shape signal you've got going into the speaker. If it's nice and sinusoidal, then great, but if it's square, bad. Underpowering is fine until you turn the volume up.

[joakwin]

thats why a ported box built to the subs specs will make the volume fine for being a underpowered system, vs a under size small sealed box, the ported box built right and tuned right will be 3-5db's louder then the same system in a sealed box

3db's in sound is equal to doubling the power to a sub

i started to build the door pods today to house the dual kenwood 4in speakers in the lower front door
when the grills are on the speakers, they are almost together, so thats why the spacing looks so far apart

gonna power them with 80w to ea door

[joakwin]

im gonna make new door cards and i will mount the pods to them

made out of 3/4 mdf, has a open back
this side is for the passager side
