Really? What's the difference? How does the amp know whether the two 4-ohm coils are on the same driver or not? (Not being sarcastic - I'd like to know why it's wrong)

He means a wire with a fuse on it. See: FUSES

Still have pop and then DC power going to sub for a short time before music kicks in. Gain and LPF were already set identically for both input channels, so no luck there. Thought I was on to something for a second. Oh well. I had the exact same problem with 3 different headunits, so that's a...

Missed your 2nd post. I believe both channels are getting the same exact signal now that I'm using the "mono bridge" wiring instead. That definitely helped a lot. The SA-8 v.1 sub is good for 400W RMS. The amp is a bit big at 300W x2 RMS continuous @ 4 ohms), but apparently people overdrive...

I've been experimenting with the LPF set at 60-80hz on the amp. No headunit at the moment, and no LPF or bass boost settings on phone/laptop. Just for kicks, I tried unplugging all RCA cables. No difference - still get the pop. Gain is set to "normal" (500mV), but have tried it at the...

Fixed the wiring to use mono output. Definitely a lot more volume coming from the sub - sounds a lot better. Unfortunately, it still has the startup pop and apparent DC output as seen in the videos. This should be 4 ohms per channel, right? Thanks for the quick reply, btw. Already made a...

Thanks for all the tips. The sub is an SA-8 D4, which is two channels at 4 ohms each (right?). Each channel from the amp powers one voice coil - no parallel hookups or criss-crossing or anything like that. I read somewhere that this was a bad idea, but I didn't see any explanation for it. Do...

What do I do with them? No connections are shown for those wires for bridged mode:

I don't know what the deal is, but BOTH of my amplifiers are having issues in bridged mode. This one, a Pioneer PRS-D4100F, puts out a pop every time it turns on. After the pop, it looks like it's putting out DC voltage, pulling the speaker cone in one direction) and holding it there for a...

It's been over a week and I've heard nothing from soundstream. No tips here either? My other amp, a Pioneer PRS-D4100F is also giving me trouble, but I'll start a separate thread for that.

A couple weeks ago one of the channels stopped playing on my pn4.520d. Turns out it's mixing both left and right signals together and only playing through one channel (right). I'm wired up based on the diagram in the manual and the labels on the amp harness. Only the top row is used (solid...

I'm seeing different widths on this thing from 9.25" to 11" - do you know the actual width? I need to fit this into the stock CD changer location, and I'm concerned about it sticking out too much if it's > 10" wide (not counting wire connections). Basically, it's going to be mounted in some...

Why do I see so many posts about Massive Audio, but not a single thread comes up if I look for the BX4? I find it strange that nobody has even mentioned it. It's way out of budget for me, but I still would expect to at least see people talking about it. The NX4 is tempting, but it seems like...

Hi all, I've been putting together a system for my Honda Insight over the last few weeks. The equipment is being taken from my MR2 (which I am selling), but I am willing to spend a little extra to upgrade a few things. Honestly, simplicity is probably my top concern - I don't think I have the...

Curious to hear if there are any more recommendations. I have about the same size constraints in my Honda Insight, to power a Sundown SA-8 and maybe MB Quart QSD 216s. I like the specs of the Precision Power P900.4, but it also scares me that the amp can draw @ 75A (900W), which is the max...
