Tuning, EQ Help

Hello All. I installed a system in my car a few months ago and its sounds ok but not what I think it should be. I have all infinity reference speakers and amps. The amp is a 475a. 4channel, 75watt rms X4 at 4ohms. It also says 90watts RMS X 4 at 2 ohms.

1. The components, (6030s), say that they can handle 90 watts RMS at 2 ohms. My question is do I have to wire the speakers up in a special way to achieve this impedance? When I originally set it up I just hooked up each component, tuned by ear and left it. I'm thinking of trying it again with a DMM or getting the DD-1.

2. The subwoofer which is a 1060w single coil is 275 watts rms at 4 ohm. So my question is do I have to wire this any differently then simply hooking it up to the positive and negative terminals? Is there any special way I have to hook it up to gain 4ohm impendance?

Thanks for looking at this. I know its not the best stuff to put in a car, but it sounds ok to me and I like it.

Also I f my sub is facing the back of the car, does that mean that I should select reverse phase or 180 degree phase on my headunit?

Im new to all this stuff so any info is appreciated.

1. No, pos and neg respectively.

2. See #1

About the sub, no, regular phase.

Thank for the reply! Does the positive and negative for the sub still the same if its bridged between to channels?

Model numbers would help a lot... but as said, just simply hook up the positives and negatives respectively. And both your speakers and subwoofers should be set with a DMM unless you want them to be damaged and fried.

Amp: Infinity 475a 4 channel. Subwoofer is the 1060w single coil. Components- 6032s 6.5 infinity. All Infinity.

Im trying to decide weather to go the dmm route or the ear route.

I just wanted to make sure I had everything wired up right and all the impedances correctly hooked up. Thanks for the replies!
