OK I have seen that quite a few of you are into stereo systems. I dabble a bit myself but am having a problem finding some information. I have 2 PPI Art series 404.2's in near mint condition. I am running my highs with one and will be bridging the other to two chanels to run my DVC sub. I lost the owners manual and I have been searching the net for specs. Don't know if any of you have them but other than the bridiging info I haven't found anything.

I know they are 50x4 but I am trying to figure out what the output would be x's 2 when I bridged it??

Any help or even a suggestion of where to look would be great.

 

PPI's site doesnt have any archives with specs? Maybe you could call them too.
Im not really sure, I would guess something like 200 wattsx2 at 4 ohm.

You've got some nice amp there

 

Yeah I tried there site but since they sold out all of their old stuff is gone. I am going to try and call them in the morning.

You would be surprised how many people I know think they aren't worth a crap compared to their new Alpine, Kenwood, etc... amps. "Its 10 years old and no built in crossovers" if they only knew.

Hey let me throw something at you when I set the gain with a DMM since I am bridging it I would use the RMS wattage of the bridged channels right?

I am building a fiberglass box in the spare tire well of my Mach to hold a Treo 10" 4ohm DVC running 1 coil off one channel and the other coil off the other channel(PPI's won't push a 2ohm load bridged) I am thinking I might have about 1.5cuft in the box which I am worried might be too big?

Any insite?

 

PPI art series are very nice amps and you're right...your friends just don't know!
Yes, to your DMM question.
What Treo sub are you talking about? Initially, I would say yes that enclouse would be too big. Is it ported or sealed?

EDIT: Try looking on Ebay to see if anyone is selling that particular amp. Seller's usually put up the specs...not sure if they would be accurate though.

 

If the PPI amp is 50 x 4 then it is rated at 200 x 2. I use to have Art series but, do not remember which. But, they all would do the same doubling of power. 50 x 4 @ 4 ohm, 100 x 2 @ 2 ohm and 200 x 2 @ 4 ohm bridged. But, they were very underated and you could throw almost any load at them. PPI Art Series are some of the best amps ever made. And of so pretty.

 

I am thinking of going with a Treo SSi 10" sub. I haven't gotten the top put onto the inclosure yet, still layering the sides and bottom I want to get them to atleast 1/2" then I am going to spray the inside with undercoating. I guess at this point I could always add in a divider wall to cut down on the air space trying to keep it as close to 1cuft as possible, then use the left over as like a storage pocket of some sort. I had thought about mounting the amps there but I want to be able to take it out easily for when I go to the track. Right now I have the amps mounted under my rear seat delete.

Think 1cuft would be too big? Oh yeah it is going to be a sealed enclosure.


So I think it would be 50x4 @ 4 ohm, 100x4 @ 2 ohm, and 200 x 2 @ 4 ohm bridged. I don't think the Art series can be bridged to a 2 ohm load without going into protect, or atleast thats what I hear. Yeah from what I have heard they are underrated big time. I have heard guys getting 90 x 4 out of the same 50x4 amp. THat would be sweet if I could run it 2 ohm bridged...I could throw out 400x2 to 1 10" sub...man that would pund lol

Its kind of funny and sad at the same time but when I was in HS I had a PPI Sedona 60x4 running the highs and a 50x2 bridged running a JL W6. One night the 60x4 stopped working so I hooked all of my highs to one side of the 50x2, and the sub to the other side and ran it like that for about a week until I figured out what was wrong with the 60x4. I must have been putting a .5ohm load on one channel and a 2 ohm load on the other chanel and the amp never shut off. Wonder how the Sedona handled that but the Art series won't handle a 2 ohm bridged load??

 

Not that I would try it but, I would bet it would run 2 ohm bridged. I do not know for how long as it would probably heat up pretty good. The Sedona's were actually better amps than what they make today. Back in the late 80's, PPI made some amps for Crutchfield. They were along the Sedona specs and they were awesome.

 

Yeah I don't think I am going to try it, I am sure 400 watts for 1 10" would be enough...plus since they underrate the amps that 400 might be closer to 500.

Anyone know how to tell how many watts you are acctually getting from an amp? Maybe with a DMM or something?

 

Yeah, running it at 2 ohm might be pushing it. I know a lot of people have ran these PPI's at 3 ohms bridged (Im thinknig of the W6/1200.2 combo a lot of people used to have) without a problem. I wouldnt doubt it would work at 2 ohm, just for how long I dont know

Speaking of 1200.2, I was thinking about grabing one for my SI Mag, I think it might be a little to much though Maybe an A600.2.

 

Well I was looking for a 600.2 for a while because they are almost the same physical size as the 404.2. I will have them set up so you can see them so I wanted good looking amps. All I could find were beat up, scratched amps and unfortunatly with the graphics on the front you can't just re-paint them.

I have had my 404.2's since 96 or 97, and have managed to keep them in great condition with no really noticable scratches.

Hey Bartek, back to the enclosure what do you think would be ideal for the SSi in a sealed box?

I wouldn't mind porting it as Treo's website says "SS woofers can be used with great success in a sealed enclosure but will offer dramatically increased output in a ported application." But they don't give you any info on port size, box size, nothing.


I guess sealed would probably be the best for an sq application anyways, I like it loud but I want it to be clean too.

 

Yeah, it seems like almost ALL the PPI Art series amps on Ebay are beat up pretty bad. Maybe its just more noticable on the white paint though. I dunno. I think I like the black ones best though

As for the enclosure, Bryan is probably the one you want to talk to when it comes to Treo. I believe he had a pair of the 10" SSi's, so he should be able to tell you better than me. I really dont have any personal experience with Treo.
