I have a 98 Nissan Maxima gxe model. Its time to replace the stock components. The tweeter is located on the door panel close to the apiller and the mid is in the typical location on the door.

I have a CDT HD62 set with the passive crossovers and DRT 26sat tweeter set.

I have a 5 channel RF Power 1000 amp that does :

Rated Power Front/Rear Channels
50 W x 4 @ 4 Ohms RMS
100 W x 4 @ 2 Ohms RMS
150 W x 4 @ 1 Ohm RMS
200 x 2 W @ 4 Ohms Bridged Mono
300 x 2 W @ 2 Ohms Bridged Mono
Sub Channel
300 W x 1 @ 4 Ohms RMS
600 W x 1 @ 2 Ohms RMS
800 W x 1 @ 1 Ohms

Total Power 1400 Watts
Bridgeable Yes (front/rear)
Crossover Controls Front Channels
High-Pass (HP): 40-400Hz 12db or 24db/Octave Linkwitz-Riley
Low-Pass (LP): 40-400Hz 12db or 24db/Octave Linkwitz-Riley
10x crossover switch
Rear Channels
High-Pass (HP): 40-400Hz 12db or 24db/Octave Linkwitz-Riley
Low-Pass (LP): 40-400Hz 12db or 24db/Octave Linkwitz-Riley
10x crossover switch

Infrasonic filter: 28Hz fixed

I was told that if i mount the tweeter farther from the mid to go active and if i mount the tweeter close to the mid to go passive and put 200 x 2 @ 4 ohm to it.

Any recommendations are appreciated. Thanks

Go passive its going to be alot easier.

What HU/Processors do you have...that determines if you can go active.

not necessarily what HU but what type of processing do you have?

Sorry, i have a Alpine CDA-9813 and it offers 3 way active crossovers. I have always gone passive so this is new to me. I dont mind going passive if my installer can find a place for the tweeter right by the mid.

There is a lot more than just how far the tweeter is from the mid. The acoustics of the car also plays a very important factor. A decision to go active or passive just on distance from the each other is a poor decision. Infact, distance from the ear is more important than distance from each speaker. Then there is also the angling of the speaker and such that also have to be taken into account.

I would recommend to hook it up passive first. If then you don't like it, then move to active.

Sounds like a good idea. Thank You

I will try and mount the tweeter closer to the mid.
