AUDISON and HERTZ SQ System Configuration-HELP

[nmmhd]

Hello

Since January 2007 i started to spend some real money in car audio (untill then...just for home). By now, already have some equip.and i feel that now is the time for the next step... intend to make a fresh start with my own hands, but... for this i count with your wisdom and help (thanks in advance) to carry this project.

The equipent avaliable is a Fiat Bravo 1.9 JTD GT:

H.U:Alpine IDA-X001 w/ New Ipod Nano Classic

AMPs:LRx2.250 (2x120 or 1x420), LRx5.600 (4x60+1x180), Infinity Ref. RA7502 (2x75 or 1x220WRMS)

SPKs:Hertz HSK 163, and Hifonics Warrior 300WRMS sub

Stinger power cables, 1Farad PCap and Oxigen Audio spk wires, will aquire Sound deadening soon to apply in front doors.

After presentation, the first questions are about what's the best possible configuration w/ the actual equipement to achieve higher SQ (I do not intend to get into competition):

1. Should i connect all the spks directly to the amps, or should i use the supplied x-over (3W10) for tweeters and mids, leaving the woofers connected directly to the AMP?

2. When we transform a 4 ch amp to 2ch mono we win power at the cost of loss of SQ...is this true? Should i use the 4ch of the Lrx5.600 to feed the woofers with 2x170 dual mono?

3. Thought in 3 diferent system configs, but please help me choose the right one for my goal. Any advice or better config, PLZ describe.

1st config: With or without X-overs? where(tw or mid)?

Lrx2.250-> 2x120 to woofers

Lrx5.600-> 2x60 to Mids

-> 2x60 to Tweeters

1x180 (Audison) or 1x220 (Infinity) to sub mono?

2nd config: With X-overs for tw and mid

Lrx2.250-> 2x120 to woofers

Lrx5.600-> 2x170 to tweeters and to Mids (dual mono) W/ X-over 3w10

1x180 (Audison) or 1x220 (Infinity) to sub mono?

3rd config: With or without x-Overs? where(tw or mid)?

LRX5.600 -> 2x170 to Woofers (dual mono)

LRX2.250 -> 2x120 to Mids

Inf.RA7502-> 2x75 to Tweeters W/ X-over 3w10

LRx5.600 -> 1x180 (Mono?)

Thanks, once again, ill wait for your guru opinions to mount.

use the LRx2.250 for your sub

the LRx5.600 bridged for your 3ways and use the Hertz xover

Hi,

I'm trying to sell the H.U.(was a very good deal), then i'll probably go for the 9887 or 9857 and go active, same with sub, when i find a good deal for a 10" Hz high-energy sub w/ closed enclosure, i'll replace hifonics, but mean wile, that's what i'll install next weekend.

The option to use lrx2.250 for the sub is great because it's simple and easy to adapt to actual car install, but lrx 5.600 already have a sub channel (week but it's there) and if Infinity can drive my sub, lrx 5.600 sub channel maybe could do the job too.

With the actual config, Lrx 2.250, to the comps, the speks seem underpowered (120x2) with gains on the amp and H.U. just one step from max they begin to come alive but that brings undesired distortion and the sound begins to melt all together and confused. Using dual mono to feed them (170x2) i'll just win less than 50W for each 3way comps, this way seem thal i'll be obligated to run the amp gain high and H.U. volume above 80% of max volume. Off course they should sound better, but probably with one of these conf. i could reduce amp levels and feed the spks at 50-75% of the H.U. volume range.

1st config: With or without X-overs? (tw and mid)?

Lrx2.250-> 2x120 to woofers

Lrx5.600-> 2x60 to Mids

-> 2x60 to Tweeters

->1x180 (Audison) or 1x220 (Infinity) to sub mono?

2nd config: With X-overs for tw and mid

Lrx2.250-> 2x120 to woofers

Lrx5.600-> 2x170 to tweeters and to Mids (dual mono) W/ X-over 3w10 modified

->1x180 (Audison) or 1x220 (Infinity) to sub mono?

Thanks

i dont think so..

It just depends on how you set it up..

Bob Marrow tends to lison to his iPod alot..

I think I can trust his $0.02 on Sound Quality

Lets See Arc Audio, Morel, Genisis Rep & Wrights for Car Audio mag

Has been into car audio for a very long time 7 has Judged..

Even a ipod ripped in lossless is still not near cd quality. I can bet he uses his ipod for the convince, in a car environment with road noise and all other factors a lossless file on and ipod and store bought cd could be hard to differentiate the two. I was more making a joke than anything but i would never use an ipod for a sq competition or in my home theater

True, I have all of most-listened to music on my Pod converted to LL, but it still doesn't compare to a CD. I just liked having all my music with me.
