Posted By: Sivart_dup1 Stiffining Capacitor questions. - 04/04/06 06:21 PM
My system will consist of an older Precision power 75w X 2 amp bridged to run two Precision power 10" subs in a sealed enclosure. A Soundstream rub600-4 which is a 50w x 4 amp that will run polk seperates in the front doors and polk coaxials in the rear doors.

First of all, would I benefit from a capacitor? Second do I just run one for the sub amp or both amps? Third is this sufficient?

If not does anyone have any better suggestions?

Another question, will a 4 ga main supply wire be sufficient to power those two amps, http://www.knukonceptz.com/productDetail.cfm?prodID=KOL4BL or do I need to go with a 0/1 ga wire?

Before you buy a capacitor, buy some real amps. No offense but those brands do not work too well.

Also, the power rating on those polks may probably be higher than 50 watts.

Are those amp specs RMS or peak because if they are peak they are no good.

Before you post, do some research chief. If it's an older PPI amp, it's more than likey one of the best quality amps you could ever buy. The Soundstream Rubicon series is no slouch either. Nice comment about the power ratings as well, you obviously don't know shat about quality car audio. I'll put my trusty little PPI A300's up against all the power you're probably running and you'll get to hear what a quality setup sounds like.

True, Soundstream and Precision Power were among the Best some years ago.

yeah my bad... i thouhgt it said soundstage... not soundstream i read it quickly

The soundstream is only a couple of years old. I got a good deal on it and I didn't realize that they had changed ownership and that the Soundstream that I used to know no longer existed. For what I paid it will do the job until I can upgrade. The PPI is about 5 maybe 6 years old. It was before they changed ownership. I have an art series in my mustang and it's a fantastic amp.

I love those. The guy who taught me how to install had one way back when, and it was just great.

Yeah I love mine. You can fry eggs on them but they never shut down.

Exactly! The older PPI amps were some of the best made. Are the new ones not as good??

I have the older series of PPI amps and they are phenomenal in reliability, clarity, and power. 4th or 2nd (switchable) order crossovers built in, seious continuous power.
I'm using a PPI 2600 (Chromed exterior) to drive my JBL W12GTi sub and it is perfectly matched.
My PPI 4100 (powdercoat gray) is again driving the front end in the Volvo and it is also very awesome. Those Bostonacoustics Pro60 speakers that I selected sound absolutely crystal, crisp and have very good bass.
I'd recommend them in a heartbeat if you can afford them.

Just FYI, I order some Polk MMC 6.5" coaxial speakers for the rear doors in order to provide the rear fill and round out the sound. I have a friend who uses the Polk Momo speakers and they are very nice for the money. I still prefer the Bostons for superior sound, just a tad more natural sounding I think but the polks will treat you really well.

Many people consider the series including the model listed above to be the last of of the superior quality PPIs. They still make good amps, but their rep has diminished a bit.

That's really too bad.

Who/what are the top of the line amplifiers these days?
Posted By: dnewma04_dup1 Re: Stiffining Capacitor questions. - 04/15/06 06:31 PM
The likes of Zapco, McIntosh, Audison, and a few others rank among the best. To be honest, I think there are much better deals on amps these days then there was 10 years ago. I don't think quality has taken the drop that some people claim and watt/$ is much better than it ever has been.

JL audio makes a good amp also.
Posted By: svt4stv Re: Stiffining Capacitor questions. - 04/15/06 10:29 PM
JL audio makes nice everything!

i used to run PPI pro mas amps. they were pretty nice but overheated like crazy. and i hated the stupid wiring harnesses. i tried a 2600 but it destroyed my subs. BUT they did make excellent stuff back in the day. id always heard about how great the Art series were. seen them, but never used them.

I used to also use Linear Power back in the day. awesome amps but always shutting down on me due to heating issues. i tried fans and what not but just too much hassle. i prefer the newer amps with their mosfet circuitry.

old Soundstream stuff was great too. and ive been using the older RF stuff for years, without any issues.

ive heard that Xtant are great amps too. i just picked up some Eclipse amps cuz i know that eclipse makes quality products. i believe Kicker amps are pretty good too.

I never had heating issues with any of my PPI amps. It was actually the old Artseries amps that I first bought and they did get hot, but the next two generations were excellent. Never have had a shutdown and I put in enough systems back in the day using the powerdercoated gray series of amps, probably ten different models of that lineup and they never had a heat issue.
Still, I was sizing the amp comfortably in the range of the speakers....:D Hey it wasn't my money. You may have been extracting every ounce of power from them, that tends to run the edge of shutdown esp on a hot day.

I've been out of the stuff too long, I don't know those amps.

I have to agree that even the cheaper amps of today provide a lot of features for the money and sound great. Comparable to many mid to high-end amps of ten years ago. I remeber when you couldn't even find an amp with a built in crossover.
The old Coustic XM5e was a mainstay electronic crossover to balance out a multiamp system. Worked great too. Coustic amps and subs are really great bang for the buck stuff too.
