Need advice: American bass amps

Anyone have any experience with this brand? I replaced my fronts and rears with JL Audio components and building an enclosure for a Sundown SA 10 in the rear. Need a 5 channel amp for power.

Any advice?

Alpine PDX V9 was another choice. My budget is 500.00 more or less.

Thanks

Yeah, the Alpine is the best choice for that price range. The Power Acoustik 5-Channel Gothic amp is a decent amp too. It's another 100(4)x500(1) and costs about $150. The PDX-V9 seems to run a little cooler though.

Also, depending where you're mounting this amp will also determine what amp you can fit in there. I had it narrowed down to two amps that i knew could fit up underneath the steering column.

I almost went with the alpine VX9 but decided on the JL 700/7 instead. Have no complaints and thing doesnt get warm at all.

If you're budget is $500 for an amp, get a quality amp and brand.

. This is sound advice. Pun intended. I'd personally opt for quality brands (JL, Alpine, RF, etc) not Internet specials. I think a $150 5 channel amp would be suspect. That's not to say I don't buy online.

I wouldn't say that just because something costs less, that it isn't quality. Its funny how no one has a problem buying a $100 dollar HU. I researched this amp thoroughly online before purchasing it. You can see awesome reviews all over the net about the Power Acoustik 5-Channel Gothic Amp. I had actually purchased it before purchasing my Alpine PDX-V9. I was having trouble with my system and I switched the PAG amp out, thinking it was the problem. The problem was a setting on my Head Unit. I wish I had the PAG and the extra $300.00 dollars back. It is a big amp,about twice the size of the Alpine PDX-V9. I don't know how it compares to the size of the JL700, but I know that it costs about $400 dollars less and has more power.

Reviews Here.
Power Acoustik GT5-2500 2500W Max, 5-Channel Gothic Series Car Amp

If you find a store that has them both, you could have them install the PAG amp first, and try it for a couple weeks. You may find its good enough with the extra $300-$500 dollars in your pocket.

OMG, what an exaggeration!! This little tiny amp compared to a football field! I threw a laughing fit. A thousand of them could fit into a football field. But, I do get your point. But, a football field? OMG! Could we fit a football field in our Jeep? LMAO!

. Hahaha, I almost posted the same thing. It's freaking gigantic. You could probably cook pancakes on it when it heats up.

I actually purchased a "MTX Audio Thunderform" molded subwoofer box which holds 2-10" Subs. Most people say that 2-10" subs are best. The MTX box comes loaded and unloaded. It's a perfect fit, and it looks and sounds awesome. I have the tan loaded one(400watts RMS) combined with my PDX-V9. This thing rocks hard. I love the way my back window vibrates.

I fit mine under the back seat and there was plenty of room there.
5" longer and 2" wider on the Power Acoustik is not the same as a football field, nor freaking gigantic. LOL.

Size Specs.

JL 10-1/4"L x 2"H x 7-3/8"W

PDX-V9 10-1/8''L x 2''H x 7-1/2"W'

PAG 15-3/4"L x 2-3/10"H x 9-3/4"W

AB PH5100 15"L x 2-1/8"H x 5-1/2"W

About the heat though, with the PAG, it did get hot. I had mine retuned and the heat was much lower and it didn't go into protection mode anymore. Sound was great though at 0.1% THD.

We need to find out where he wants to mount it. I remove my back seat too often so that wasnt an option in my case.

Yeah, I agree on both points.

Point 1- Where he wants to mount it.

Point 2- I agree that putting the amp under the back seats creates a problem if you want to remove the seat and want clean space back there for sliding stuff, and, piling stuff on the amp is probably not a good idea. It also ruins the clean look with the back seat out. I will probably relocate mine when I put bedliner down. I'm just not sure that under the dash is a good place. Inside the rear door is probably too close to the subwoofer, and with the slamming of the door, it could ruin the amp. Under the front seats there isn't enough room. The only place left would be the side, around or on, the rear wheel well. All the wires and the cramp space under the dash is probably not good for a passively cooled amp. It would be great if the amp was actively cooled. But, I have yet to see a actively cooled, high power, 5-Channel amp.

I looked at all the same amps myself. I had Jl in my last vehicle and had nothing but problems with it and was true diehard JL man before that . I decided this time to go with a Helix Audio B Five due to the fact they are owned by Brax audio and made in Germany not China or Korea. I am also going to use a Helix DSP. I have heard good stuff about Alpine also. is that MTX box made out of plastic????

Made from durable polyurethane resin. It is very thick, textured and durable too. It is not brittle. It feels almost soft.

Yeah, I like the Alpine too. But they need room to circulate the air or some way to move the heat off them. Let me know how it goes with the heat there if it fits. I may move mine there too if it works.

Have you looked at the skinnypedal mount for your alpine? It suspends the amp properly without the amp being upside down under the steering column. I find mine has plenty of airflow and the amp stays cool to touch. If it did ever het warm under there I would look at adding a small cooling fan so I can keep it hidden and out of the elements but hasnt been a problem in hot FL yet.

Yeah, that does look pretty awesome. Does it strap around the underside of the steering column?

Thanks for the info. I am so glad I traded up on it now. At least I know now where to move the amp when I put in my bedliner. It looks like there is plenty of air flow too. This forum is an invaluable tool for sure, and its members. Cheers.

I've seen it mounted upside down and right side up. I wonder which is best for maximum air flow. It seems that the upside down approach is best because this is the way the amp was made to breathe. I just wonder if its okay to mount the amp upside down?

Here is a picture I found with it mounted right side up.

It really doesn't matter with airflow on those pdx amps... they really don't thermal as long as you are running the 4 channels at 4ohm and the sub channel at no less than 2ohms...and not have the gains past 3/4
