does it sound better or worse when you are only playing one sub at a time?

I would ground them individually if it was me. I would also run another run from alt to battery as well. If you are doubling up all your grounds it probably makes sense to double up the + as well.

I can't imagine that port being too much for either of those scenarios at all. I'm probably not the best person to ask though, sorry! lol

What subs and amp are you running? Got any enclosure specs yet?

How much port area are you considering? If I remember correctly from some posts that I can't seem to find any more, it's pretty tough to get too much port area. I'm pretty sure you should be more worried about not enough than too much.

I just google that head unit, it's a subout (lowpass output only) and rear out. Not much you can do with that one. Agree with @SnowDrifter, no harm in using a splitter though. It's a 2V pre out, you'd have to be running quite a few amps before a splitter would be an issue.

What kind of head unit is it?

What is your volume setting on the head unit when you set your gains?

you're welcome!

I had it in a couple different vehicles. The first was maybe 3 feet, second was probably closer to 6 feet. As far as fuse, if it isn't popping you are fine as long as it is not higher than the wires rating. Also, my amp would be hot without playing any music as well. Forgot to mention that earlier.

My t1500 bdcp was always on the verge of being to hot to touch. I contacted RF and they said it was fine. According to them its just how efficient the heat sinks are. I ran it basically just like you are (0g to distro and 4g to amp) for years without an issue. I wouldn't worry about it if I were you.

That’s really old tech my dude. I had a 306.2 when it was already old tech and had issues at times getting to connect. You might just need to get a new processor.

It doesn't matter. It's a parallel circuit either way so to the alternator sees them as one. That being said, one wire from alt to batt1 then from batt1 to batt2 means you have to run less wire. Edit: Assuming your wire can carry enough current.

Sorry I wasn't very clear. I didn't mean to run them that way, I was asking about testing them both connected the same way. If you are only checking the Sky High speakers when you bridge the amp then it could be something weird happening when you bridge the amp. I was just suggesting to connect them unbridged to either the front or rear outputs to see if the sound improves. I have never had any luck when it comes to bridging amps and running mids and highs. Last time I tried I had a 4 channel RF amp and it sounded like ass when I bridged it. I connected the speakers to the front channels and it sounded just fine.

A lot of stuff to read, but have you tried a comparison running both sets on the amplifier without it being bridged? I realize the output level for the sky high will be pretty low since they are 8 ohm but I wonder if they sound better this way.
