I'm happy I can help a newbie. I remember when I was one and I'm happy to help you. First off, I nodiced that the fuse is only a 30 amp fuse. A quick way to see what is probably the max output of your amp is take the fuse value, in your case 30 and multiply it by the voltage you will be supplying it. Lets say you are just sitting with the car off the voltage would be 12ish volts. So your total assumed wattage is 360 watts. Which is an large amount less than the 1000watts listed. So watch out for that. Also, with subs you would want a mono-block class-d amplifier. If you need any more help at all, let me know. Good luck

Infinity Subwoofer input signal mystery


Have you tried changing the connector leads? They can become faulty. Powered Subwoofers generally work off one connector from the amp. The Sub is a mono amp basaically. So all it needs is the main imput and an earth. One possibilty is that you have the wrong jack plug. Say a stereo instead of a mono, or the wrong size one!

This means you have a dual voice coil sub. It is probably a dual 4 ohm voice coil. If you hook up the left channel to one input and the right to the other you can safely push the sub but the amp will be running at a lower efficency. In other words it isn't the best amp for the job because it can't push max power to a dual voice coil speaker but it will work.

Connect Bose 901 eq to Denon avr 2807


There's good news and bad news. The bad news you need a separate amp because a multichannel receiver with Bose 901's attached as recommended for a standard stereo receiver will only sound right in STEREO on stereo analog material. The other speakers around the room are not designed to receive its Active Equalization and if you engage your Tape Monitor you will NOT BE ABLE TO HEAR DIGITAL sources at all. Tape Monitor is for analog stereo material only and on modern AV receivers it disables any digital inputs so you really can't use the Tape Monitor circuit or attached devices for modern digital sources. However, you can still employ the Tape Monitor with any type of stereo-only sound processor (non-Bose EQ, dbx expander, etc) and the various DSP options to spread 2-channel analog source material around the room. I have a whole stack of analog processors, tape and CD recorders slaved to my single Tape Monitor and then into a dbx400x Program Route Selector. It not only expands my Tape Monitor to handle nearly unlimited external devices but it makes routing for listening or recording easy with simple pushbuttons. But I digress...

The good news. I have a setup similar to what you want to do and it works great! With one caveat - My receiver actually has 5.1 analog Outputs (probably like yours) so I can drive up to 6 external amplifiers if I want to (I drive 4).

A separate stereo amp for the 901's was my solution. I run a Carver AV-406 (5-channel amp) for my 901's in Front, 2 Subwoofers and the Rear Surround channel, with the Active EQ between the receiver Front L&R Outputs and the 901's amp channels. My receiver controls everything and just drives the Center and Surround speakers.

You could get by with just a stereo amp for the 901's. A Carver M-200 is a good efficient amplifier that would have you cooking just fine (2x100W). Run it with the Active EQ between the receiver Front L&R Pre-Outputs ** and the 901's amp channels.
** Front L&R Pre Out >>> Bose EQ Amplifer IN, then
Bose EQ Amplier OUT >>> NEW amplifier IN.

Attach the 901's to the new amp, set its volume to Max and run through your receiver's speaker level setup.

Infinity Basslink killing battery


Both issues sound like they are related to a non-connected or loosely connected remote wire on the Basslink.

If you're using RCA preamp wires to connect your stereo to the Basslink, make sure the remote wire input on the Basslink is solidly connected to the stereo's remote output.

If you're using the speaker level inputs on the Basslink and not the RCA preamps, make sure the remote input is not connected, as the Basslink will automatically turn on when it senses the speaker level inputs are active.

Car stereo crossovers


you should be able to remove the passive in-line crossover, but since it is blocking everything below 3500 hz, there is no need. leaving the passive crossover in place will also help protect the tweeters if something fails in your setup as any amped frequency below 3500 can seriously damage them.
