Oops! 300/2. That's better.

Does 800W in total amp power mean I am always drawing 800W with both amps on? Or is that just maximimum if I had the volume turned up to 100%? If I keep my volume at 50% (17/35 on my Alpine HU) does that mean I'm only pulling 400W? Got this answer back from Optima: "800W = 67 amps. Even when...

I'm running a JL 300/1 for my fronts and a 500/1 for my sub. So I guess that means 800 watts max. total? I keep the volume at about 50% and the car is always running when I run my system. Car is an '07 Impreza STI with stock alternator. I've done the BIG 3 and use 4 guage wiring throughout. Any...

I've read the sticky ground loop thread a few times and also reviewed many other grounding threads. I'm not getting "alt whine" but instead two different noises that sound like pops and squelches. The pops are clearly pops. The squelches are almost squeaks but not as high pitched. LOL, don't...

Buy very thin alum. sheet metal from home depot, it comes in sheets, only about $10 or so. Use tin snips to cut out shapes that are a little larger than your holes. I used deadener matt to secure mine down, plus some heavy duty glue stuff from a caulk gun, mostly just the matt though, my glue...

This is an interesting comment "still image quite well". From what I've read, putting the tweeters up high brings the soundstage up, not sure how putting them so low sounds good. Which way would you point them if you had them by the woofers? Facing toward the driver, middle of the car, or the...

Sail panel seems popular. Do you also use time alignment to delay the sound from the nearest speakers?

Was reading the speaker FAQ regarding tweeters... My setup is fronts, 2 way component speakers, MB Quart QSC216 6.5", car is Impreza WRX. My tweeters are in my door panel, much closer to my ears than my woofers. So if I go -3db or -6db on my crossover settings, can that have the same impact as...

Curious why J3 is saying to leave some small holes for air to pass through? If nothing is living in your trunk, why is that needed?

I listen to mostly prog. rock, rock, and metal and I'm crossing over my fronts to sub at 80HZ with a -18 db/octave slope using my Alpine CDA9813 HU. So far this sounds pretty good. Anything higher like 100HZ and I start getting music out of my sub. Anything lower like 63HZ I can't really tell a...

So is it bad for my battery to start my car with the HU and heater/air conditioner on? Does it make a difference? My HU feeds into 800 watts of amps, that also come on via the remote wires.

Old thread but I want to try this - Do you have to disconnect the terminal that goes to the negative post on the battery? And then you hook up your DMM lead to the - battery post, or the the terminal? Also, how do you check the resistance of your extension wire? Supposed to subtract that...

Okay, I'm going to do one of these. But which is better: Grounding to the amp ground location or the battery? Does grounding the HU to the amp ground somehow prevent a "ground loop" but grounding to the battery would not prevent this? Both options are about the same level of work to get to, so...

Thanks for the tips. I just spent an hour separating my RCA and power wires - about 6-12" separating them now (12" most of the way). My RCA does run on my chasis floor under my carpet, but for now I'm going to accept that. My RCA is Knuconceptz from their amp kit and I think shielded. Yeah, all...

What kind of noises could I hear if my RCA and Power cable are next to each other? Should it be a hissing/static noise? Or could it be any kind of noise? I think when I did my install I didn't separate those 2 cables very well even though I read this tip 20 times. I'm getting a noise sometimes...
