Question for all the ICE experts

[piggyboyz]

Hi Guys,

I have a amp that is able to run at 2x110 or 2x190 watt @ 4ohm and 2 ohm respectively. The THD listed is 0.3 and 0.4 respectively.

My question are -

Would it be ok to get 2 sets of component speakers at 4ohm rating, run it parallel so that it would be 2ohm and use the 2 channel amp

or

Get a set of 2 or 4 ohm speakers and use the amp.

What r the disadvantage of running the amp / speakers at 2 ohm loading ?

Pls enlighten.

Thank you

hi Bro, v interesting topic indeed.

try to answer straight to point, tho actuali lotsa reasoning behind...
- if you're audiophile : 2ohm.
if non-audiophile : 4ohm.
- disadvantage of 2ohm load : amp die/de-grade faster (bottom line)

just curious:
1. wat's ur idea of running 2 parallel 4-ohm speaks?
2. how to install? Front-rear/Front-rear config?

btw, think there may be professionals & experts out there who might disagree, but i'm also open to learn... me no expert actuali, just sharing fm a little experience and some studies

Thanks for the reply.

My tot was to run the front and rear component via one amp to achieve the 2ohm loading since my amp is able to run at 2ohm loading. Reason being i want to maximise the amp that i have without having to take up too much boot space with some decent sound better than the stock ICE.

cheers

Re: Question for all the ICE experts

i see... in that case, if u don't mind a little 'sacrifice' in terms of lifespan of the amp, just get a 2ohm, 3way component for the FRONT ONLY, and dump the rear (no speakers).

You don't really need it unless you plan to do 5.1 system.

Parallel on the F/R will give rather 'unacceptable' sound (louder version of the stock) imho.

ur problem now: i'm out of touch with current product market, so can't reco you any good 2ohm, 3-way component speakers. but there are lotsa excellent 4ohm, 3-way though, which i think you can easily pluck off any good installer/shop.

happy icing!

Hi there,

Thanks for the explaination.

Guess I will use another amp or swap the 2x2 channel for a 1x4 channel amp then

Cheers

Re: Question for all the ICE experts

hi piggyboyz... come to think of it, i have an idea you MIGHT wana consider.

a good 4ohm 2-way 6.5" or 7" component front.
a good 4ohm 4" parallel for the front.
(an combination/alternative to a 2ohm 3-way component front)

i've heard many systems, and also done up one of my friends rather large & appropriately insulated and dampened MPV (Toyota Picnic) and found that it sounded good (comp standard) even without the rear speakers (read: NO rear speakers).

a good 3-way front can give you surprisingly good sound, with a good clear amp.

for your 'alternative' consideration, den u can max ur 2ohm capable amp, and max the space, max the sound quality. saves weight (ok ok... insignificant...) on removing ur rear speakers.

Hi Alan..


IMHO, running your amp in 2 ohms mode has several disadvantages, the amp runs hotter cos more output current is being generated and this created more noise (explained in the increase in THD) and with this setup, you cannot fade your music and balance your front to rear speakers.

If you want to keep weight down, stick to original headunit and get a set of really efficient component speakers for the front and a set of co-axials for the rear. Total cost < $800.

Next step use an amp for your front speakers only. This will greatly improve your sound stage. If you have a 4 ch amp, you can power the 3rd and 4th ch to your rear or subs.

Normally, the 2ohms mode is used for subs only..

Cheers

Re: Question for all the ICE experts

Hey piggyz, Hope i read your question correctly....

190w to power 2 speakers wired parallel.
vs 110w to power 1 speaker

power wise, i wud go for option 2. Firstly, u save money on one set of speakers. U can use the same amount of money and buy another amp if u need more power. Then u bridge each 2 channel amp into mono, power increase by alot.

not to mention also tuning issues etc....

your amp must also be 2 ohm stable....

hope i make sense...cos i no expert also.
