Separate names with a comma.
Wiring that way is called parallel wiring. If your sub is a 2ohm DVC, your amp is seeing 1ohm. If it's a 4ohm DVC, your amp is seeing 2ohms. If...
Sounds like your amp can't take the ohm load. What model is your amp and what is the voice coil configuration of your sub?
Yeah, PPI is awesome stuff. I had an A600.2 back in the late '90s. Wish I hadn't sold it years ago. I still run my old Crossfire 1000D, though. :D
What are the dimensions & vent measurements? Or do you know what it's tuned to?
Is your box sealed or vented? I don't see that mentioned anywhere.
According to the Kenwood site, the KAC-9105D Class D is 1ohm stable. Under General Features: "1-ohm stable (output regulated to 900 Watts)"...
Did you check to see if the turn-on lead or the RCA cables are grounding/shorting somewhere? Pinched speaker wire somewhere in the car maybe?...
Sounds like Ranger has it right--bigger box & better tuning. The guys here can help you tune your box right. They definitely helped me get my box...
You don't need to get to the speaker itself, just the amp. Change which channel the speaker is wired to on the amp so you can see if the speaker...
:D Those old hatchback Type-10 Cavaliers from the late '80s are awesome for bass, too. One of my high school friends had one of these back in the...
I'd get a Firebird, 6 speed, V8, '98-'02. :) Probably not gonna get 25mpg, though. lol
Okay, then a 1ohm stable mono amp would be fine for it. I'll leave it up to others for advice on which amp would be best for your budget.
The resistance of your sub determines what resistance your amp "sees". Your amp would see a 2ohm load with that sub, regardless if the amp is 1ohm...
You wouldn't really need to tear anything apart, just connect the wires that are currently on a "good" channel to the channel you think there is a...
You can check the remote wire by just running a jumper on the amp itself from the 12V+ to the remote turn on connection. If your amp turns on,...
Try grounding your HU somewhere else besides using the black harness wire. You can also just connect the red & yellow wires to see if your HU will...
There should be a yellow wire you need to hook up for the switched power.
How about a box in the bed with a blow-through from the bed into the cabin? :D I want to try this when I get a truck.
Which set of preouts does he have the amp wired to on the HU and where are the 4 speakers mounted? Or maybe he wired the speakers to the HU...
Wow, man, that sucks! Something's definitely awry. Have you checked the output on the amp's speaker terminals with a DMM or oscilloscope? You...
