bam334 Posted June 24, 2018 Report Share Posted June 24, 2018 I’m running 2 sets of Memphis SixFive series 6.5” components on a JBL Gtr104 amp. Pioneer 490 double din. Wondering which option is better for getting some extra “sparkle” out of my tweeters. Leave them set at 0db(flat) on the crossover and boost the deck EQ a bit to compensate, or set them to +3db on the crossover and leave them flat or cut a bit on the deck EQ. Which is better on the amp/passive crossover as far as keeping the signal clean and not introducing extra stress(heat) at the amp/crossover? 85 caprice classic -Paint and Body -Billet silver metallic under ice blue pearl - midnight blue vinyl top -all chrome replaced -Interior -smoke grey with blue inserts and piping Audio - coming soon Link to comment Share on other sites More sharing options...

Joshdashef Posted June 24, 2018 Report Share Posted June 24, 2018 I spent a couple days finding the optimal tweeter setting for my setup. Try it out as ^^^ said and see what you like best.

bam334 Posted June 25, 2018 Author Report Share Posted June 25, 2018 The sound is great. I was really surprised with em. I turned off the built in cross over on the HU just to see how they sound completely full pass and they play really clean and they do it loudly. They’re at about 90 Watts@2ohms. Of course they’ll be highpassed with the substage on. My question was more about what’s better for them and the amp longevity wise. Flat on the passive crossover and boosted on HU or flat on the HU and +3 on the passive crossover. This is my first “done correctly” set up so I wanted to be sure. 85 caprice classic -Paint and Body -Billet silver metallic under ice blue pearl - midnight blue vinyl top -all chrome replaced -Interior -smoke grey with blue inserts and piping Audio - coming soon Link to comment Share on other sites More sharing options...
rambronco Posted August 3, 2018 Report Share Posted August 3, 2018 You will be less likely to clip the signal with +3 on the passive and flat on the eq. I always prefer to to take peaks out with the eq rather than boost any of the frequencies, thats not always an option but its the game plan i always start with. 01 Chevy Silverado X-cab 2 Sundown Z18v4 walled on 2 Lanzar Opti 7k's strapped at 1/2ohm = each amp wired to 1/4ohm. Havent checked impedence rise so not sure what they are actually seeing. 6 group 31AGM's. 2-Eclipse 34230's each one running 2 Eminence 6.5" Beta 6A. These are beastly mids rated at 350w program power. I was skeptical but the eclipse amps are 370w x 2 and when there was 4 mids on 1 amp I could push it into thermal protect within a song so added the 2nd amp. Eclipse 4212 running 4 CT sounds Meso tweeters. and 2 DLS ultimate tweeters up high to raise the soundstage. 96' Ford F350 4wd 4d long bed 7.3 diesel with 91k miles. Will be the sound quality rig if I can ever find the time. Link to comment Share on other sites More sharing options...
