Here's what I'm looking at:

JBL px300.4 http://www.ikesound.com/product-product_id/1651

JLaudio 300/4 http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=11726

PPI pcx-480 http://www.ikesound.com/product-product_id/1809

Audiobahn A4601T http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=13499

One of those would be dandy, anyone have any experience with them.. or suggestions to another? Looking to power 4 speakers with around 300 watts.

Check out the Visonik 4208 on eBay...around $140US or so. An excellent amp. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

For MBquarts.. Discus and Premiums. I believe they're 90watts rms, but I think 75 will do fine. All 4 amps are the same power, excluding efficiency.

No experience with any of those, but I'm also looking for a new 4 channel amp and I'll comment just based on specs and price -

The JBL doesn't list HP/LP filter range. I like HP to be adjustable from 50 Hz up. Power doubles with 2 ohm loads, which gives you the option of another pair of speakers in the future without losing power to the first set.

The JL unit has great specs except that the power is the same for 4 ohms or 2 ohms. It's also nice and small.

Specs on the PPI are excellent. A big sucker tho.

The Audiobahn is also small size, and 18dB/Octave filters.

Personally I'm partial to R.F. amps, because their input circuitry really works for noise canceling. The RF 801 is 100 watts per channel and cost about the same as your other choices on eBay:

Wow, you know your amps..

Good info there, I considered RF.. but I find myself impartial, just because it's RF.. got a bit RF'd out over the years. Man, I truly can't make a decision here.

In my case I have criteria that help narrow down the choices:

1) I have some alternator whine caused by a ground loop that's been eluding me for over a year. All the RF amps I've tried (with the exact same install) are quiet as a mouse. I like that.

2) I want more than the 65 watts @ 4 ohms that my present amp provides. My 5.25" Resolutions will take more.

3) I intend to add kickpanels in the future, with 6.5" components and use the 5.25" door mounts for dedicated midbass (probably Focal W5's). I want an amp that'll handle both sets, a 2 ohm load.

4) My amp rack is 17" tall. That's the limit for size if I want to hide the amp. Also need to keep room for crossovers, so width matters too.

If none of these issues apply to you, it realy is hard to choose.

yo get a ground loop islator that i will stop the that noise.
