i am just making a new thread cause the other one was getting cluttered. i know some of you compete and have an eclipse hu. have you ever tired a different hu with the same set up? i know by changing hu u can gain or loose a few tenths of a db. i know cheaper hu with 2 volt outputs are not as good for spl. so by getting the cd7200 and getting 8 volts would it win hands down?
how can i tell the best spl HU.
a guy that works at the local car audio store around my school told me that eclipse is designed to slowly take away up to 3 db "depending on the set up" the reason that you will have better sq with out over powering bass. but he read this in 1995 or 1996 and says they are still like that but he says some stupid stuff. prolly just trying to sell me something because they dont have eclipse.
i just wanted to know if any one has tried many HU with the same system on a meter and could tell any difference and if so how much.
The 8 volt preout is good and eclipse is good company as well. The higher voltage can help for spl but is limited to what your amps can accept voltage wise. Bottom line id go for the eclipse if there isnt any known issues because a clean 6 volts per say on a rd 3250 is good since its the max it can except and yet your deck is able to produce up to 8 giving you a very clean voltage to your amp. There is some to be gained with a little distortion but I would rather keep the signal clean and have equipment last longer.
Hes talking if your running below the ohm load your amp can handle but if you dont have sufficient electrical/battery your amp will shut off early also depending. Wiring below ohm load cuts down box rise but sometimes you can cut box rise down too much and your amp will shut off because of it.
Basically answering the question you just typed out...
Scott, I burp at .5ohm and I shock the mic with my volume at 40/62 (5750.1) should I be concerned about damage to the amp or anything as I really DONT have sufficient electrical to support it....I'm a bad boy.
Pretty much not overly concerned with competing anymore for the next year as I'm going to go with loud daily but I just want to know what techniques are better than others as rolling the volume takes....forever.
Lasted the whole summer @ .5 with many, many burps
I just have the big 3, one battery and a 160a alt. Head lights don't even dim until I really crank the begezes out of it, but that's just dumb right there.
Gains were set by ear and are failry generous and are not cranked by any means.
For my daily next year I've got two deep cycle Discovery RV batteries that I will be using along with a HO alt/Big 3 in whatever new vehicle I get so that should be a decent electrical set up, just have to keep the batteries topped up.
i'd never run a 7200mkii for spl.. they are built for sq.. yes they have high output rcas but how many amps accept 8v.. most high end sq amps do.. but rear amps designed for shear power do..
they might accept something close.. like 7v.. but remember you key is to match it as perfect as you can so you don't end up with a dirty signal
if this is just for a basic system.. i'd suggest the cd3200 if your stuck on eclipse
i dont wanna interupt this thread but i just gotta quick question. my amp only has up to 4 volt for the rca's. is it ok if i get a eclipse hu that has 8v(which i plan on getting is theres no problems)?
jack! u said if i am stuck on eclipse. i am not stuck on anything. i just want the best. so with my 1750s what HU would u say is best? i do like the look of the eclipse and the blue tooth and all that stuff is also nice. but if i can gain a small amount of spl any other way i am all for it
alright so i looked up my amp. i can set the gain from .2 to 6 volts. so looks like 5 volt rcas would be perfect! hope i looked at everything right.
KEVEN what times are good for me to call you? idk when u work or what is best. i don't want to wake u up if ur sleeping or call u at work.... but u do work at an audio place so idk

so you are running them at a .5 strap correct. this is where you should roll the volume. it will help the amp get to peak ohm load when the box rise starts taking affect. you might be able to shock the system if you get .33 each on those amps. i have found rolling isn't as hard on the equipment. btw i dont use pioneer to slow of a roll. i now use a kenwood excel. because it has a superfast roll feature and a 5v rca out. remember the smaller the box, the higher the box rise.
i dont know what rolling the volume is. i am guessing it just turning it up during the burp so it is not full power at first. so should i consider the kenwood excel over the eclipse?
i would. yeap turning it up while burping. the eclipse and pioneer have a slow roll while the kenwood have a super fast roll. my pioneer take 4sec to get full roll and the kenwood takes 1.5. it makes a diff.
ok that is what it thought.the kenwood i have now is 4 volt pre outs. .... that eclipse looks nice with that bluetooth already built it! so how is having a slower roll bad? i would just have to burp a split sec longer
depending on the amp and ohm load you may or may not be able to do a full power burp. in cases with low ohm loads ypu may have to roll the volume. ie my dc's at .25 i have to roll my rd's i dont because they ohm at .33 depends on imp rise and power supply.
