Use the crossovers that came with the speakers. They work the best because they were made specifically for that speaker. You shouldnt need an external 3 way crossover unless your head-unit has only 1 set of preamp outputs or if you want to seperate the signal going to 3 different amps(1 for highs, 1 for mids, and 1 or more for the subs). Unless you want to do any of the above you dont need one. Also since you already have 3 ways up front, which should be plenty of highs, then you shouldnt need three ways in back also. Besides, if to much sound comes from the rear it ruins your imaging up front. 6 X 9s are for rear fill usually. Sounds like a pretty good system. Hope it turns out well!

Stinger's SWK4D wiring kit has all of the power and ground cable you will need plus a distrubution block. Speaker wire and rca cables usually dont come with multi amp wiring kits because the manufacture dosnt know how many or what lengths you need. So.. you will need at least 2 Hyper or Nitro rca cables and some pro or custom pro speaker wire.

Stinger makes excellent products. Yes their speaker wire is good! Some 14 gauge wire should be fine for your subs and 14 or 16 for your speakers.

The ground wire is attached from the negative - terminal on the amp to the metal of the vehicle. Do a search on grounds for more information.

so are the ground wires teh same wires as power as in the same material ....not purpose
Posted By: customsuburb

Yes the ground wire is the same material. If you buy an amp wiring kit the outer jacket might be a different color but is really the same wire as the power wire for an amp.

two questions 1) the 6 1/2 speakrs(infinti kappa perfects 3way) are 75rms and 225 max watts.would it be safe to run 125watts rms to them? 2) teh crossover settings on my amp and on my speakers. since teh speakers have a crossover how should i set teh crossover on the amp example if it set my midrange amp for the infintys at Highpass at about 100hz and up should i do the same for the crossover on the speakers need help plz are crunch amps anygood?

I would be careful if you were running 125 watts RMS to the 6.5" speakers(be careful with the gain knob on your amp). Your speaker crossovers are adjustable? If they are then you should leave your amp's crossover setting on full range or off. If your speaker's crossovers arn't adjustable then try these settings: for the crossover settings on your amp, I would set the rear channels(or what ever 2 channels you use for your 6 X 9 speakers) to full range. For the front speakers I would try setting the crossover on full range(or off) and seeing how it sounds and then trying a high pass crossover setting of around 80 to 100 hz. The high pass crossover would give you cleaner sound but you might like the full range setting better because your speakers may sound like they lack some lower midrange(60 to 120 hz or so) signals.

If you mean by "im not worried about low frequencies" that you don't want your speakers besides the sub to play low frequencies then the above settings i mentioned are what you need. -------------

what u think about that crunch amp
Posted By: customsuburb
Date Posted: February 22, 2004 at 9:09 PM
I have never heard a Crunch amp before. If you don't want spend alot of money on an amp but still want good sound look at US Acoustics. Their USB-4065 would be a good match for your speakers. If you want to spend a little more look at JL, Eclipse, or Alpine. They make good amps too. -------------
