I have the following equipment (all figures in RMS):
- JBL GTO75.4 Amplifier (104W x 4ch @ 4ohms OR 142W x 4ch @ 2ohms OR 284W x 2 @ 4ohms)
- JBL GTO6507SC Components (60W - 2ohms)
- JBL GTO1002D Subwoofer (250W)
- Pioneer 4-way 6x9s (80W)
- JVC mp3 receiver with built-in MOSFET amplifier 50W x 4 peak (20 watts rms)
Set-up 1 (Only subs on amp):
- Each sub will be bridged over 2 channels to utilise the 284W @ 4ohms
- Since subs are dual voice coil 2ohm, I can wire it in series to get 4ohm load
- Components and 6x9s will be running off the deck
Set-up 2 (Subs and components on amp):
- Subs running off the two rear channels, only getting 104W @ 4ohms each
- Components running off two front channels, utilising 142W @ 2ohms each
- 6x9s will be running off the deck
Set-up 3 (Everything on amp):
- Subs running off the two rear channels, only getting 104W @ 4ohms each
- Components running off one front channel, utilising 104W @ 4ohms split between the two speakers (wired in serie to get 4ohm load)
- 6x9s running off other front channel, utilising 142W @ 2ohms split between the two speakers (wired in parallel to get 2ohm load)
Three questions:
1)Which set-up would be the best?
2)Would the last set-up cause any problems?
3)Is there anyway to get the dual voice coil 2ohm subs to each present the amp with a 2ohm load?
I think set-up 2 would probably be the best all-round set-up, since then the 6x9s will only be for rear fill and not fully powered. Can I please have your inputs.
Thanks
