On the Sundown amps they are remote gain knobs.

Are you talking about the store Civic music?

Test it out. Hook up a mp3 player to the amps and bypass the head unit.

Do all headunits have pico fuse in them or just Pioneer? If all headunits have a Pico fuse in them then why don Pioneers' always fail more than others? I was riding around one day and my one of my subwoofer wires came loose from the terminal and hit the terminals that encase the ground, power and remote wire. So know when my car is on the Sundown SAX-125.2 is now making screaching noise that gets louder with speed or when accessories are turned on or turn the ac to a higher setting. It only happens when the car is on, when the car is off or key in the acc position it doesnt make the sound. I also plugged up my mp3 player and househould boombox to the amp when the car is on and there is no screaching. So Im thinking I must of messed up the headunit somehow, it is a Kenwood Excelon KDC-X492. Thanks for any information bromo and sorry to thread jack. No not all head units use a fuse on the grounds of the rcas. Some use a resistor. When I had my pico fuse problem there was not a slight whine from the alternator. It was more like an unbearably screaching noise emitting from all the speakers, I couldn't even sit in my car when it was happening. I do get a slight alternator whine from the deck every now and then, it comes and goes. I am going to try and ground the deck better to eliminate it when it gets a little warmer out.

Plugging and unplugging the RCAs while musics playing. I blew mine from testing the amps and accidentally touching a screwdriver to the amp case while touching the remote terminal. To test if you blew it put you multimeter on the continuity test and touch one lead to the outer rca connector and the other to the chassis of the head unit. If its not blown you will hear a beep meaning you have continuity through the fuse.

No. I believe the ones in the deck are rated for .5 amps and just doing a quick search you can find ones rated up to 30 amps.

Kinda curious as to why you have the ports off axis from the subs like that. If you draw them up in Google sketch up you can check the volume with a little math.

Its 4.5" LENGTH after the corner of the port. Not width. It's stilll 5" wide. Nice design! Not talking about the length that is given. 15.25" port wall + .75" for the second wall = 16" 20.5" of internal depth - 16" = 4.5" away from the rear wall. Not to mention if it was 5" from the back it would be tuned to 34hz

I see no tweeter in your sig, in fact I seen no sig. A lot of people have sigs turned off.

I'd be wary of that design it doesn't quite add up right. Just at a quick glance the port width is 5" but at the back wall it is only 4.5".

What subs are you using? Voice coils specifically.

Well if you have one btl on a SAZ-2000D, and you're adding another btl.... you can't power them both with the SAZ-2000D. Why not?

When I saw this I thought, " Sampson, Simpson, Swanson....... Samsonite man I was way off."

Well lets see some pics then.

The type cvx will.

Glad you found one in the collection, I forgot it was there. If you want one with different dimensions let me know I can whip one up and if you want I could also get creative and do one.

I'm not adding any airspace. The displacements are subtracted from the volume and for reference the displacements I am talking about are like bracing(which there is none in this instance) and sub. Your off because your calculating to much port displacement. 1. The physical port is only 21" long. So you have an extra .021ft^3 2. You are accounting for 6.25" of port wall that is not there. So then you have an extra .0352ft^3 So your 2.2795ft^3 + (.0352+.021) = 2.33ft^3 that I calculated.

CVX's are either D2 ohm or D4 ohm, you want D4 ohm and wire them like this.
