PPI or RF Amp

[Ray]

I'm upgrading my system to Infinity's Component 5 1/4" and 6"x9".

I'm thinking to use PPI PCX-480(80w RMS x 4 4Ohms)

also RF Punch 800.4 (100w RMS x 4 4Ohms)seems a nice amp too.

Dont mention about money but the sound quality...!! Which would do better to match with Infinity's high db speakers?

rf will give you bass but i dont think that they have very good sq so i would go with the ppi

Right now I gonna bid a Brand New PPI amp in EBAY...It just cost around $350

I though It's worth!...But y so cheap for a BRAND NEW AMP??

Any risk buying amp there?????

I just bought a couple of amps through ebay. (Good Deals!) As long as you are cautious you should be ok. Just look at things like feedback., Do they have pictures of the product...etc. Anyway, PPI is a good choice they make a quality products.

The difference in the 2 amps would be slight if any. They're both quality products, both under-rated to the best of my knowledge.

If I were you I'd get the one with the most power for the best price.

Speaker quality, the amount of power they're being driven with, and inherent system noise are much bigger sq factors than what brand of amp you're using.

I heard that ppi is on the way out, again!, but they do know how to make amps so does rf but if you need sound quality for mid and highs no question ppi if you want to push 18s then rf

i about had an orgasm when i took my ppi (pc2150) apart to powder coat it, upgraded the heatsink compound to military grade =), and alot better insulator pads or whatever they are called, i also put a higher cfm cooling fan in it, it rocks!! the output transuistors on this are rated 200 watts power disappations, and there are 8 of them i believe, been awhile since i had it apart.. anyways this amp is my new girlfriend... =P
