So I bought a JL 450/4 acorrding to specs that were on the website I bought it from and they are WAY off, it's a whole 6.25 inches longer then I thought it would be and is not even close to fitting under my seat, 99' Dakota ex cab.

Now I'm looking at the PDX and I have heard it before and it had very good clarity on a pair of Focals. I've read that they have less punch when comparing the 1.1000 to the 1000/1 but have not read anything in that regards to the 4.150 and it's punch and was looking for info from people experencied with both. I'll be powering OZ ME 180CS up front and Infiniti Kappa 652.7i in the rear.

The PDX amp's are "underrated"  These little bad boys are awsome. Power, size, ease of install, fit and finish,

The size......this is the part that amazes me the most. That 1.1000 is the same size as the 2.150 smaller than a standard sheet of paper.

Read this test. It's very concise.

That looks good, thanks for the link.

When I went to check one out last night I was only able to compare it to a Focal amp and a JL 300/4 of all the amps the focal was the loudest and JL the cleanest the PDX sounded like it was in a small tunnel or something. That being said I was testing it with Focal speakers and the week before a few amps weren't even wired correctly to work, so I'm taking it all with some salt.

The 450/4 seems to have a better crossover but my 980BT has a built in crossover that is a little better the the one in the PDX. So I think probably gonna go with the 4.150. I'm gonna see if any stores in the city carry it so I can get a btter idea if it's the amp I want to run. Install would be a snap though!!
