Optima yellow tops are good i hear, XS power batteries. you should look around for a local battery shop though, I got a very nice battery, a Northstar AGM from a local store that came with a 4 year full warranty for a lot cheaper than I would have paid for an equivalent XS Power battery or something similar online.

Isn't wiring your subs out of phase not good? I'm not an expert but I've never heard of anyone purposely wiring their stuff out of phase. Anyway though, upgrading from your stock battery would be the next step for you. Get the biggest AGM battery you can fit under the hood and you should be good. I had the same problem and replacing my battery fixed it 100%. Also I don't know about your amp but it could be inefficient. I have an old kicker amp that when wired to 4 ohms produces 500 watts of power, It causes my lights to dim at full tilt when running my Crescendo BC2K at 2 ohms (1100 watts) rarely makes my lights dim. Technically the kicker should present less of a load but I assume its the effiency of each amplifier that makes the difference.

I've been waiting for someone to say something like this forever. Can you or someone please elaborate some more on all of this?

Ill have to see if its still under warranty. Thanks a lot for your help with everything man!

I've already tried three pairs of rca cables and I just fully unhooked my deck and brought it inside to closely look at the wiring of it and everythjng was mint.

Soso it passed the aux to rca test that means my deck is blown or its wiring is bad?

Okay I will try this tomorrow

Yes I have and evertthing appears to be connected properly

New update on this situation here... I plugged my old amp in and the subs still hsd the same problem. then I tried the subs on a buddies amp in his csr and thwy worked. I've checked all of my wiring 16 times so is it possible that something messed up in my deck? I have a pioneer deh4800p. I noticed that when I mess around with the volume knob on my deck the subs will momentarily cut in.

Yes thats right, Ill contact them first thing tomorrow thanks for your input man.

I guess I can try to open it up and take a look.. I wouldn't really know what im looking at but a loose speaker connection should be easy to spot out right

So I've had my BC2000D for about two weeks. I've only had it running on 4 ohms for 3-4 days and then 2 ohms for the other two weeks or so ive had it. It's been playing mint and today i was just driving around, had my music playing at about 10/62 for half an hour and then i decided to turn it up a little bit. I had it around 20/62 and then my subs just cut out. I went to look at the amp cause its in the back seat and they go back on, they went back off again and then just stopped coming on at all. No protection light and they still have power. I was even playing them earlier this day for almost an hour at near full tilt. I've checked everything fifteen times, the ground is fine and I know it because I have another amplifier grounded to the same bolt (on top of the bc2000d so if it was the ground this one definitely wouldnt work), I tried using three different pairs of rca cables ( which work with my other amp), the power wire is hooked up to my battery perfectly still, I redid the wires going to the box and the subs and still no output. Like nothing at all. Throughout me checking all of this it did cut on for 2 seconds about three times. It seems as though theres a bad connection inside the amplifier or something. Anyone have any thoughts on this? I'm going to try and call Crescendo tomorrow and see what they say. I'm so disappointed Ive gone broke trying to have a decent reliable setup and am still having problems..

If my clipping light is going off does that mean my amp is definitely clipping then? Since its producing DC voltage i cant hear? But the clipping light is worthless because the amp can be clipping even when the light isnt going off? Or is it that the clipping light usually goes off before the amp clips? And Welter, your saying you believe I can run 2200 watts off just a second battery without buying the 190a alt?

Alright well i guess its time to save uo some more dough. Thanks everyone for your input

I'm debating on the alternator, I got a quote from singer and they said 439 shipped for a direct bolt on 190amp alt. mechman has nothjng for my car and I don't know where to get an adapter bracket made aroubd here. the problem is I don't reallly ljke my car and probly wjll want to get a new one soon and an alternator won't be somethj g j could transfer into a new car or get my money back for throygh selling it. I was hoping I'd be able to get by with just a second batteru for now but I might seriously consider getting an alternator. Just how nuch of an jncrease in output should I expect going from 2 vvxs at 1100 watts to 2 of those subs I listed at 2200 watts? would it be worth the money spent?
