Title: need advice
Post by: sharki786 on 24 November 2010, 14:04

hi all,

I have this http://www.thebassbin.co.uk/product.php?id=749 (http://www.thebassbin.co.uk/product.php?id=749) JBL GTO 6526e in my car (all 4) running from http://reviews.cnet.com/in-dash-car-stereos/alpine-cde-9850ri-radio/1707-6729_7-31848244.html (http://reviews.cnet.com/in-dash-car-stereos/alpine-cde-9850ri-radio/1707-6729_7-31848244.html) Alpine CDE-9850Ri would it be better to use an amp?

CD Player is 50 x 4
Speakers are: 180 W RMS
Thank you

Sharki

the speakers are only 60rms (180 watts is peak power so ignore that)
yes you will be fine running off the stereo but personally i would fit an amp as the h/u power quoted is max power which actually equates to around 4x12 rms

REALY?  :huh: oh yes i just had a look and its not RMS. how is RMS calculated? also what is the total rms of the speakers?

Title: Re: need advice
Post by: troublestarter on 24 November 2010, 15:04

the total rms is 60rms per pair as in 30rms per speaker

i might aswell get an amp for them, but theres also 4 power acoustic tweeters in the car. i have a budget of £50-£70 on a 4 channel amp or is that too less?
p.s these are the tweeters http://www.google.co.uk/products/catalog?hl=en&q=power+acoustik+tweeters&sqi=2&cid=15311031687616493784&ei=864GTf3zI5XIwAXv9vjqDA&sa=title&ved=0CAcQ8wIwADgA#p (http://www.google.co.uk/products/catalog?hl=en&q=power+acoustik+tweeters&sqi=2&cid=15311031687616493784&ei=864GTf3zI5XIwAXv9vjqDA&sa=title&ved=0CAcQ8wIwADgA#p)

you ideally want an amp that will do around 30-60 rms per channel at 4ohm to run the speakers well

if i was to get an amp that has more rms then speakers, that should be ok? rather then have powerful speakers then amp? will be getting a jbl 60w rms 4 channel

Chances are your going to f**k your speakers if the amp is putting too much through them, better to have a little less running through them and have them run forever, than to put a massive amp on them and blow them up!

i thought running more powerful speakers throught a low powered amp could mashup the amp??

If the difference is stupidly great, ie. 4 x 250 speakers running through a 4 channel 200 amp, then maybe it might do something to the amp, but i would be very suprised if it did tbh, in all my experience i have found it's safer to run a little bit less than you actually are capable of.

you should only really bridge subs and run sat speakers as normal
