Need some help with a Yukon system

PGPhanatic · Post by **PGPhanatic** » Wed Aug 06, 2008 2:07 pm

What's up. I'm a damn newb here but a long time PG Phan. Anyway, I just bought a '97 GMC Yukon and I'm researching what I want to do with the stereo setup. I'm gonna be using an Eclipse 8051 passive reciever, (I know it's a little dated but it rocks), and all PG speakers, subs and amps. I plan on using the rsd6.5 components in the front and rear doors, and rsd6x9's in the factory 4x10 location in the rear. Here's my question's....I will be using the ti series amps to power both mids and subs. What amp should I run for the six midrange drivers? I was thinking the zx500.4ti but I'm not sure if I can run six mids off of it. Any suggestions? Also, I'm planning on getting two ti elite 12's. Would the zx1200.1ti be enough for both of them? Or would a couple of zx600ti's (one for each) be suitable. I'm glad I found this site and hope someone can help me out. I would like to do this myself. Thanks.

i personally cant help with your current dillema cuz i've got no experience with ti stuff...however, i have heard that the elites will work well on that power, but can really excel with alot more... but anywho, i wanted to say WELCOME!! just hang tight and im sure that our experts will be chiming in for ya shortly...good luck!

the rsd comps should come with a passive crossover, so you wont need a seperate amp for the mids and tweets.

when you say passive receiver, thats the one with no on-board amp?

the 500.4 would do ok powering them all, but not ideal

if it was me, i would either snag a 400.2 & a 500.4 and use the 400.2 for just the fronts. OR do away with 1 of the back sets (probably the rear doors) and just run 4 speakers.

as for the subs, the TI elites need A TON of power, they wont reach their full potential without a true 1200 RMS each, and even then you could go higher.

i would either just go with 1, or switch to a pair of RSDc12's

Thanks for the welcome. I used to own a zx400.2ti and ran a pair of PG 15" dvc off it. That amp was the shit. I went to our local audio shop, Benchmark Auto, and they said I could use a four channel to run all the mids as long as the amp would handle the ohm ratings/load. They're a reputable shop and have had success but I still dont know if I would want to go that route.

they are correct the amp will be able to handle it, the problem is you will have no way of adjusting the rear 6x9's VS the rear door components because they will be on the same channel.

i still maintain eliminating the rear door speakers is the cheaper and better way to go.

I know the rsd comps come with their own crossovers, and I wasn't planning on buying an amp just for the tweets. I'm just stating that I would like to keep all six speakers working, just to keep me happy inside

As for my reciever, yes, it does not have an on-board amp. It just acts as a signal so everything is ran satellite. I paid $850 for it new, top stuff in it's day. The only thing that sucks about it is it's dated and looks kinda "cheesy" compared to the new h/u out now. As for powering my mids, The other route I was thinking would be to get a 500.4ti for the comps, and maybe an rsd 2-channel hidden for the 6x9's. I've been away from the audio world for a little bit and my knowledge is not up to date. Does PG have a smaller ti amp rather than the 400.2? I've seen the zx275.2 but it wasn't a ti. I know the elite 12" sub needs gobs of power, and I might just settle for one with a 1200.1 ti amp on it. I'm just not sure what route to go yet.

A dead-head HU and six speaker location plus sub makes it hard to do with even two amps while maintain balance and fade controls of some type. That idea is made harder by the fact that your sub wants a ton of power.

There's always the Ti900.7

However, since the 900.7 actually has five mid/high channels, it's still not perfectly ideal. But, if you're thinking about being a bit insane, you could run a Ti1200.1 to the sub, the sub channels on the 900.7 to the 6x9's, the front/rear channels to their respective speakers and leave the center unhooked (you won't be "wasting" that channel either!).

This way too, you could have an LPL for both the sub(s) and the 6x9s, pretty cool.

Just a thought. A pretty wild thought.

the 400.2 is the smallest amp in the TI line up. the 900.7 is a pretty good idea

I agree with Brian... Elites are going to need a 1200.1 EACH... good luck getting that to power them, you'd need a biiig alternator. I'd also recommend the RSD Comp subwoofers. They are far more efficient, and 1200 watts could easily run a pair. Either that, or run a single Elite... but with 6 speakers, that may leave you desiring more.

I think running the rear speaker sets in parallel would work out fine. I would probably recommend 6.5" coaxes for the rear doors, just to keep the efficiency nearly the same as the 6x9's. 6.5" comps will be noticably quieter when run together with them, due to the passive crossover absorbing some wattage.

Odds are you want your rear channels much quieter than the front, so you would run them together, and turn down the volume by quite a bit. The amp will have no trouble running them at 2 ohms stereo. The only issue is you can't turn them down independently of one another, but for rear fill, that's probably not a big deal at all. As long as you give them their own RCA feed, you can fade the four rear speakers in or out completely from the headunit as you see fit.

So a 500.4 and 1200.1 could run your proposed setup. If you got a 900.7, I would personally bridge the front and rear together for 300x2 on the front stage, and use the sub channels to power the rear fill in parallel as well. I think having 300 watts on the front stage would be way better than having independent volume control on rear fill.

Thanks for the ideas/inputs. I did come across the idea of the 900.7 for all the mids, but that is alot of powering for the amps since I do plan on a 1200.1. I think I'll just eliminate a set of mids. You all say the rear doors. I guess the 6x9's would make up for them. In my mind I think it wouldn't "sound efficient" if I eliminate the doors. I just didn't want a "dead spot" in the doors, catch my drift? But then again the rear fills are angled toward the front so you would hear them quite well. What do you all suggest? Rear doors or rear fills? So if I have the rsd6.5 comps up front and the rsd6x9's out back, the 500.4 would work them well together on the same amp? I dont want to get to crazy with this setup, just to sound good and close to harmoney.

Many of the guys here won't even run speakers in the back, just front components (or 3-way) and a sub(s). From a purist's point of view, you only want sound coming at you from the front for stereo sound.

Post by **stipud** » Fri Aug 08, 2008 7:17 am

In that case, I would personally leave out the 6x9's, and just do the front and rear doors. I have heard both setups in SUVs, and preferred the more forward speaker setup. The rear fill was less uhhh... rear sounding.

PGPhanatic · Post by **PGPhanatic** » Fri Aug 08, 2008 2:09 pm

Ok. I'll leave the 6x9's out and stick with the doors. So all in all, this is what I'll be using. The eclipse 8051 h/u, rsd6.5 comps in the doors, a ti elite 12" sub, ti500.4 for the mids and a 1200.1 for the sub. Sound good? Open to any other suggestions if the 500.4 is ok to run the mids. Thanks.

Sounds perfect

Post by **Bfowler** » Fri Aug 08, 2008 2:32 pm

that all sounds like it should kick ass.

the only other advice i have is deaden the hell out of the inside of the doors. cover any holes in it to create a baffle for your mids

PGPhanatic · Post by **PGPhanatic** » Fri Aug 08, 2008 2:41 pm

Thanks for the help. I'm glad ass hell to have found this site. I will be deadining the whole inside if the yukon when I gather all my pieces. Again, thanks to all.
