bit of an upgrade . dam my ears are ringing

[leesturbo]

nice . new infinity kappa perfect's 6.1 .......100watts rms ouch . they weigh a ton too.
bit of door chopping action was needed lmao
old cav turbo door speakers meet infinity perfects 6.1
it looks like a full on sub, but its only 6.5"
.

lmao

Awesome! David and Goliath.

nice.are they deer to by? i want to upgrade my door speakers?where did you get them from? looks nice mate

[wallopsri]

i considered the perfects for my cav, but decided against them because the frequency range wasn't suitable for my needs. they are imo extremely well built and reliable, but like i say the freq range let them down a little. in the end i went for the kappa's at 95dB sensitivity and a freq range from 45hz upwards with an impedence of 2ohm's,(effectively doubling the amps available output to 4x 150watts rms).

they have been available at some reasonable prices, but availability at the moment is a little sketchy;

what amp are you driving these units with?

what sub & amp are you running in conjunction with these?

infinity amp 97watts rms one.
the 2 ohm will double your amp output but the kappa's will still only handle 270w
but the perfects 400w

[wallopsri]

infinity amp 97watts rms one.

what about your sub?

[leesturbo]

what about your sub?

lmao

[wallopsri]

lmao

are you running a sub?

are you running a sub?

not yet

[wallopsri]

not yet

at present you have little or no sound reproduction below 70hz then,(not sure what the roll off slope is like on the perfects), judging by your avatar and cars output figures your not looking to increase weight significantlylmao , check out these subs,http://caraudiosecurity.com/shop/pro...s_id/2423.html, recommended sealed enclosure volume is around half that of a std prefab enclosure.

i was on a weight shedding mission so emptied the boot of ps2,dvd,dsp,avcontrol/amps,240v inverter, all was installed in mdf and carpeted racks.
it was a huge weight and the car was noticably quicker with it all removed, but then all that stuff sold on ebay and i had cash in paypal hmmmmm infinity speakers and amp was itching to be bought lmao the weight is alot less than what was in the car before tho

[f4af100uk]

they are some sexy speakers them!

infinitys rock my mate and i both have set-ups in our cav turbos front and rears

infinitys rock my mate and i both have set-ups in our cav turbos front and rears

mine arn't much better than the std's i took out
i haven't installed them with mdf baffles etc but they are fairly solidly mounted, i would of expected it to not be at there best but alot better than the std one.
the amp starts clipping at under half power too.
my ipod has crackles at low volume too, it didn't have any with the old amp. and it still doesn't if i connect it to my home hifi using the same rca's!!! the amp is silent with no inputs connected.

tbh mate, it's not the amp nor speakers, it's the source,(i-pod's along with i-pod driven transmitters are notoriously unreliable in a car enviroment).

is yours this one,http://catalog.belkin.com/IWCatProdu...duct_Id=297313, or the earlier version?

you should also consider the amps specs,http://caraudiosecurity.com/shop/pro...s_id/2858.html, with a signal to noise ratio of only 83dB, noise will be a problem if using a weak input voltage.

you must remember an amplifier can only amplify the signal it recieves, it cannot improve it's quality, as the speakers will only reproduce sound according to the information they recieve from the amp, and so a poor source signal, coupled with a low input voltage,(higher gain setting), and a fairly low signal to noise ratio will add up to a little induced amp noise. unfortunately the only way to improve this is to improve the source,(new headunit incorporating i-pod control).

in your position you should also consider the speakers you selected, they will only play down to 75hz, so i would give serious consideration to high passing them at around this figure,(it may well improve quality and output).


with regard no noise on home system, this being a home system i would expect a signal to noise ratio thats much higher.

with regard the use of stock plastic speaker mounting adapters, to improve these simply remove the speaker adapter from the door, cover the mounting face with a bead of silicone or similar, now remount to the door, once tightened run a bead of silicone round the inner edge, using a wet finger smooth the bead into the join. leave for 24 hours to cure,(do not fit speakers till silicone is fully cured, during curing it gives off chemicals which may damage the speakers), also run a bead of silicone around the actual face that holds the speaker, again using a wet finger spread this bead out to give coverage similar to that of a gasket,(this will seal the speaker to the adapter when you come to refit it).

as far as sound deadening goes, get as much on the outer door skin as possible,(easiest way is to use small strips passed through the various holes in the inner door skin), when deadening the inner skin simply cover any holes,(but avoid fouling any control rods or mechanisms), use a heat source to warm the deadening,(hair dryer or heat gun), and don't forget to do the outer circumference of the speaker adapter.

recommend a headunit i don't have a head unit at the mo. what input voltage will that amp take? 3v like the pioneer put out?
and does that inturn allow the gain to be low?
i do have trouble coming to terms with the ipod/blutooth being a bad source when listening through headphones the sound is mint like wise bluetooth or hard wired rca's to my home stereo its mint but if sound to noises ratio's are wildly different then so be it. i'll get what i need / you advise

just borrow a headunit of a mate, connect it up and try it, the hiss should not be present.

if the hiss is present,(which it won't ), then you may have a faulty item,(but i doubt it).

most manufacturers have now released headunits that no longer require expensive i-pod interfaces, (Alpine have a few i-pod full speed units).

i noticed with my i-pod that the output quality drops off dramatically after half volume, this gets worse if you start to adjust the eq's.

the above aren't recommendations, they are simply a suggestion,(based on the basic requirements of---2 ch amp driving front components with possibly a sub at a later date).

HTH mate.
