Quick question...
 

Amps....

I want a 4.3.2 amp if I'm getting a sub and front components, right...?

so you will be runing it in tri mode

basically means sub will be bridged on channels 3 and 4 or 1 and 2 and the the other two channels for the components

just need the RMS of the sub and the RMS of the components and your budget ??

:err:
I haven't a clue dude... Was looking at a 12" JBL Sub and also a JBL amp too...

your beter going 4 seperate amps unless ur buyin alpine etc etc:y:

like said a mono and 2 channel would be better but a 4 channel will be just as good plus saves space

best to get the speakers first then ill pick you a few options for amps :y:

Not sure of your budget mate, so can't really recommend any components. JBL do some fantastic gear for the money, especially their amps and their older GT4 sub.

The older model sub (the GT4) will out perform the new model (GTO1202D) in every aspect except for the fact that the newer model can be wired to show more power from an amp. But unfortunatly they can't handle that extra power (unlike the GT4) therefore that is pretty useless.

JBL GT4
JBL GT01202D

Don't be put off by the fact that it is the older model. It sounds clearer and louder than the GTO mainly because it can handle a lot more power on a daily basis. It's also cheaper.

As far as the amps go you'll be pushed to find a better amp for the money than the JBL GTO75.4. This amp will power both the sub and the components nicely. There is no need to go with seperate amps it's just more hassle.

If you don't have a set of components in mind tell us what budget you have to work and i'm sure you'll get some good recommendations. If you can afford £90. Then you can get your hands on the best entry level components available, either the Boston Acoustics S50 or the Rainbow SLX230.

Hope this helps at all.
