Amp Specs:

Maximum Output Power 4 x 260 W (4Ω)

4 x 400 W (2Ω)

2 x 800 W (4Ω bridged)

CEA 2006 Power (THD + N = 1%) 4 x 130 W (10 Hz - 50 kHz / 4Ω)

2 x 400 W (1 kHz / 4Ω bridged)

4 x 200 W (1 kHz / 2Ω)

75 dBA (ref: 1 W into 4Ω)

Continuous power output (RMS)4 x 100 W (20 Hz - 20 kHz)

4 x 150 W (1 kHz / 2Ω)

4 x 125 W (1 kHz / 1Ω)

2 x 300 W (1 kHz / 4Ω bridge)

2 x 250 W (1 kHz / 2Ω bridge)

Frequency response10 - 50000 Hz

Distortion

S/N ratio> 95 dB

LPF40 - 500 Hz (-12 dB/oct)

HPF40 - 500 Hz (-12 dB/oct)

​

I have also bought a dual amp wiring kit from Rockford Fosgate which allows me to add another amp if needed (0 gauge), my vision is to have the setup done with a 3x channel, 2 of them running the 6x9 and a single subwoofer, and if the sound doesn't suites me I may add 2x6.5" to the front doors and add a small amp to feed it or hook the main amp as 4 channel and buy a mono amp for a sub.

question is: which Sub should I go for to get maximum benefit? do I go for a dual 4 ohm or single 4ohm? how much power will my 3rd channel will be able to dash out (RMS)?

I've googled for an answer but the dual coil / single coil part confuses me.

please help

I would get a nice set of comps, separate mids and tweets with crossovers to the front doors most likely 6.5 inch set. I would then use a a two channel amp to run those. If you want to run rear speakers just get an average set of coax speakers and use the headunit/stereo to power them on your rear channel with the front channel going to the two channel amp for the fronts. Then get a mono sub amp. Most mono amps put out their max power at 1 ohm. To get a sub that can wire down to 1 ohm you need a dual 2 ohm sub and wire it in parallel or you can get two dual 4 ohm subs and wire them in parallel. Another option is to get a 5 channel amp and you can wire 4 door speakers to the 4 full range channels and the 5th channel will be used to power the sub. The reason why I suggested the two channel amp and a separate sub amp is that for better overall sound you should spend most of your money and effort on the front speakers and amp.
