Amp for 2 Subs

[wedgiekray]

Hi Folks,

It looks like i may be employed soon \o/ so I'm doing some virtual shopping until pay day and been going round in circles for most the afternoon trying to work the following out...

I've got a 4ch amp to drive 4 speakers and was hoping to drive 2x 10" 300w (rms) subs with another amp, but so far I've not come up trumps, most 4channel amps bridged give different outputs per bridged channels, ie. channels 3/4 higher than 1/2. So is the only solution to use 2 mono amps? In which case do i just chain all three amps together sequentially, so..

source -> 4ch amp -> mono amp -> mono amp

...or split the input cable and use seperate inputs on each amp, so...

source -> 4ch amp
source -> mono amp
source -> mono amp

Most of my kit is Alpine so would prefer to keep it that way, i know it'd be more sensible to have one larger sub, but... I'd like to have two :)

Cheers for any help

Personally id use 2x mono blocks, all running separate huge cabling from a seperate battery in the boot mate.
Get the Alpine mono blocks, i had one and i couldnt fault it, in any way, there awsome!!!!

Nice one, you've got me sold on those, I'll wait till after christmas and maybe someone will be ebaying their unwanted christmas pressies.

I was going to be having two batteries in the car soon anyway for a project, how you keeping your second one charged up? I remember reading about some alternator tricks you can do but can't for the life of me find the thread.

Cheers!
