New and need help

First off I would like to say high to every one.Think I'll be spending a lot of time and money here!hahahh

Second off I have a Alpine7997 head unit,1 Alpine MRV-540 main amp running 4SPR-574 A's type R component door spks.I only have the 1 RCA pre out on the head unit for a sub running to my 1st Alpine MRD-M300 mono amp,then I'm Y jacked to my second Mrd-M300 mono amp.The mono's are wired to 2 Type S 1022D'S 2+2 ohms subs.Should or could I use the pre-out on the 540 that reads ch.1-3/ch3-4 for my second mono amp instead of Y jackin it?And would it make a difference?This in a 98 F150 exstended cab and pounds pretty good.I like SOLID bass for music like Megadeth ect. Subs are fireing down right behind the front seats.

Am I getting the most from these monos running the 2+2's.I was thinking of stepping them up to type R's soon.Plus I was wondering if one of these amps would push a type R 12 4+4ohm

One more thing is this wired properly in pic?

noooo that is wired soo wrong ok heres how ya do it.... u got 2 of those little wire thingers in tha package with ure sub... the black one goes from (-) to (-) and the red goes from the (+) to (+) then use one set of the spring terminals (use one side or the other) example.... dont use the positve all the way to the left and the negative all the way to the right... use a (+)(-) set on ONE side.... should be like this

..........Rj -Bj Rj - Bj

.........(+) (-) (+) (-)

............FA

FA=from amp

RJ= red jumper wire

Bj= black jumper wire

and that is how u properly wire a 2005 DVC alpine sub

I will try that.I know when Mobile Conceps in Chicago hooked them up the first time when I really turned up the volume nob I got a E-2 or E-3 error code and the amps shut down.One code excessive current and the other is exsessive voltage.I took it back and they actually removed a jumper wire and that problem was gone.They have been like this a year and a half.

Do you have the manual? It should explain how to properly wire them. I tried to get it online, but I dont have an alpine password.

Here is a pic of the 2+2 omh set up.My MRD300"s I'm pretty sure aren't 1 ohm stable so what I get from this diagram is 4 ohm hook up only.Am I correct.I see nothing like in my first pic.

Yes, 4ohm to each amp is the only safe way to power them. It doesnt look like they did anything wrong, they simply wired the jumper to the outside + and - terminals instead of the inside. I am not 100% sure, but it looks wired correctly. You could switch the jumper and input wires if you are not comfortable. I would try it, it cant hurt. Again, I wouldnt run them at 1ohm though.

Hope I helped a little.
