Did I do it right?!?

[c_hayhurst 10+ year member]

After much pain and frustration, I got my subs hooked up. Since I had to do all this by myself and it was my first time dealing with hooking up a trunk battery to power a sub amp, could you please tell me if I did it right. Here is: the system:

Amp for the speakers:

Professionally installed using a 4 gauge wiring kit running 4x50W RMS, works perfectly.

Amp for the subs, which I just did using 1/0 gauge wires:

1/0 gauge wire from the engine battery to the positive terminal of the trunk battery

1/0 gauge wire from the trunk battery to the power terminal of the sub amp

1/0 gauge wire from the negative terminal of the trunk battery to the ground terminal of the sub amp

1/0 gauge wire from the negative terminal of the trunk battery to car's frame

Am I missing anything? I have to go to bed and am afraid that if I did it wrong, my car will burn up overnight. Here are some pictures. Please tell me if I did this right. If not, what did I do wrong?

The sub amp is a Hifonics Brutus 2008D, rated at 1200 W RMS, running 2 DVC subs rated at 700W RMS each, wired for a 2-Ohm load.

did you fuse the power wire near the front battery and near the back battery?

Seems pretty good, What about the fuses? 1 after hood battery and one before and after trunk battery?

x2....and make yur grounds as short as possible

the wire going from you positive on batt to amp is way too long...you will get less resistance by making it shorter

oh and is the battery going to stay put like that? you may want to secure it if you have not already.

any fuses at all you need 3 in there.. 1 by front battery 2 by back battery(1 on the batt-batt line 1 on the batt-amp line)

I am going to install the fuses (no, really, I swear!).

Going to shorten the cables as needed.

My main concern is that I didn't totally screw up. Waking up to a car fire in the middle of the night is not high on my list of "fun things to do".

looks right for the most part. could be cleaned up a little. make sure to install the fuses. and secure that battery.

I don't think it will burn up over night //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif I've had a lot worse on mine temporarily not burn up.

Fuse already by engine battery. The others are coming. In the meantime, I will be removing the trunk battery, disconnecting the sub amp and taping up the engine-to-trunk battery cable to prevent fire.

Can you tell I am terrified of setting my car on fire?

x2. just check everything over before you turn it on. not much you can mess up. just take your time and you should be good.

I ran my system like you had it for some time at first before I learned better. It will be fine for over night with no juice to it.

I think the worst that would happen is your weaker battery will draw your stronger battery down some.

If I'm wrong some one can correct me though.
