what vc configuration on the subs?

or

what is the final load at the amp(ohms)?

each amp is run off a seperate channel on the amp, not sure what final ohm load is or really how to work that out i read how to do it but never took time to understand it sorry.

if the subs are svc 4ohm, and the amp is a monoblock, then the final load is 2ohm and you have 1500wrms to work with from the amp.

Assuming you set the gains correctly @ 1100wrms, you will see just under 80amps from the alternator. This assuming 100% efficiency and 14volts.

Realistically, you will not see 1100wrms with daily use. Therefore, you will be fine with the alternator and both amps.

However this is just my opinion.

edit: I would still do a high current battery

ok so at this point using both amps and not upgrading anything i will be fine, in taht case for R500 this side of the ocean which really isnt that much is it worth trying to get another 20amps out of the alternator or not rally bother?

for all that work and money, 20 amps won't matter.....leave it be

ok you mentioned that you would still doa high current battery is that so as to cut out the dimming of the lights?

yes....it will be more efficient at removing the spikes from the load than the stock battery, and then do the "big 3" upgrade to minimize the resistance between the alternator and batteries/amps
