I worked on an 02 impala yesterday. There was a factory amplifier up under the rear deck in between the 6x9's. Yours might not have it but you might wanna take a peek just to be sure. Mine doesn't, luckily. I checked and it doesn't have the "premium sound" feature. I thought that could ha...

I did get the subs to work properly by setting the LPF on the HU itself (evidently the amp's filter sucks or is a shallow slope.) I do have an amp laying around at my parents house that I'm going to hook up to the main speakers. I'm pretty sure the HU's internal amp is fried after talking to the sel...

The car is a 2001 Chevy Impala. There is no stock amplifier to bypass, and yes the speakers are hooked up. The speakers are aftermarkets and worked with my older aftermarket HU.

Yeah it does. I have the internal amp turned on.

I just installed an Alpine CDA-9831 and no sound is coming out of the main speakers. My subs seem to be playing what the mains are supposed to even though the LPF is set at 80 on the sub amp itself. The mains aren't hooked up to an amp, just the head unit. The RCA's are in the correct spot (I double...

I figured I'd better do it with 0 gauge from what I've read. Might as well do it correctly once

That 4 channel amp was bought used, so I'm not positive if it came with the four 25A fuses originally though that would make sense so there wouldn't be problems with 2 ohms. I'll just leave them be. Thanks for the replies. I will do the rewiring and see if everything works out!

Right now only my subs are hooked up with a 4 gauge power and ground. The fuse is 75 and right now they are hooked up in 4 ohms (its a 2 channel amp and I just hooked one sub to each channel but the signal is mono.) Should I hook the subs up in parallel? The 4 channel amp is not hooked up yet. It ha...

For the power, that is a lot of current draw IMO. You say redo your big 3, what size wire have you ran for the big 3? If you decide to get another alternator, in my experience it is usually cheaper to have your existing alt. rewound to a larger capacity. What size fuses are on the amp? Like I said,...

I'm going to be installing an amp for my main speakers and already have one installed for subs. I'm just wondering if I have to worry about my alternator keeping up and want to see what others think before putting in the second amp. The two amps are 310 @ 2 channels and 75 @ 4 channels with fuses of...
