Hooking up 2 sub amps?

[efm80 10+ year member]

was gonna hook up 2 sub amps(Jl HD750) to a 12w7 each. I also have a HD600/4 for my mids and highs. I have a Premier deck with 3 4volt preout (front, rear, and sub) Now I do not install my equipment, I have a guy that does, but how would you add the 2nd sub amp?? Does the 4 channel hd600 only use one set of pre-outs??? please help! also with 2 seperate sub amps going to 2 seperate subs in the same enclosure is that good, bad ,or whatever??? Is it imperative to tune the amps identical??? thanks!

Do your amps have RCA's IN/OUT?

if you look the first post was 6:18PM and the bump was 6:21AM. It was a 12 hour bump..come on now, I am not that impatient! but anyways yes my amps have RCA's in/out. Its the JL HD750/1. I am getting 2 of them

Sorry, just wokeup then //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I'm pretty sure you can run RCAs from the HU to one amp, then from that amp, take the out and plug those into the in on the other amp.

and yes the acv have to match EXACTLY on both amps if they are in a shared enclosure.
