got a maxima 97

what is the A/C pressure when the system is off?

Im looking for a program to create partitions. not the simple one from microsoft but one that you can actually choose which sectors of the hdd will be used at the partition you create.

for example sector 1-700000 will be partition 1.

and sectors 700050-1000000 will be partition 2.

does jumping the ratio up by one cause noticeable ride comfort on those tire sizes?

got a 97 maxima where the condenser is in front of the radiator.

i noticed that when the car moves with 1000 RPM the ac cools better than when the car sits on traffic with 1000 RPM.

questions are:

1. will upgrading the condenser to a thicker one provide better AC performance?

2. will it help to add a fan at the front that blows air at the condenser? (2 fans are behind the radiator which is behind the condenser. condenser is still the original one)

in my car, i got 4 component speakers each 55W and peak 160W at 4ohms

im looking for a quality amp to run them.

currently im using an amp with 4 channels that shows peak watts of something unrealistic which i dont care about :)

it has 2 x 20amp fuses so i think it has about 40-50W per channel at 4ohms.

i bridge that to get it above 100W so i can get it up to loud volume if i need it. but even with that, my pre-amp knob is already 1/4 close to distorting. yes it plays loud but its bridged, lowering impedance to the amp usually increases THD .

and i can only power 2 speakers that way. so my rear speakers are powered by my head unit because of that.

im looking to upgrade and i like the hifonics zxi150.4

and the MB Quart ONX4.125

i need to power all 4 speakers with one amp this time.

id rather get a strong amp and play loud without clipping than getting a weaker amp that clips when i play loud. and with something stronger i can keep the pre-amp knob further away from distorting. i'm after quality without spending too much on an amp :)

what do you think about those 2 amps, and can you suggest other ones?

I am building my subwoofer box out of marine plywood 3/4" thick.

dimensions is 30x14x8.

the driver i use is the JL 12w3v2.

thanks :)
