I've got a JL 500/1 Class D I'm not using if you are interested as well. It's been sitting on the shelf for about 3 years since I sold the car it was in. I used to run two JL 10's in a JL factory box off of it.

I'm not sure what its worth, make offer I suppose...

I hear ya. I grew up poor myself. Come to think of it, im still poor! WTF

I have those aura amps, and 4 Alpine Marine 7'' coaxials, and 2 alpine marine 10'' subs under the rear bench. No need to get crazy, I aint gonna drown out those dry stellings!

I am running "AURA" amplifiers. They were manufactured in 1996, and installed in my boat then. They still work like champs. "AURA'' wasn't a big name, but quality made in the USA stuff from the 90's. 17 years on these units! In a boat!

For the most part, there isn't much out there today, that i'd spend money on. I'd rather buy some used stuff from 20 years ago, like Soundstream, ADS, PPI, US Amps, orion, zapco, etc. Maybe this winter I'll put a nice system together.

+1,,you know how much old schook stuff i have laying around?? remember the the old hifonics amps,,i still have a few of those in my donzi and in the suburban i have a punch 300 driving my rear sub and rear speakers,,still thumps and gets me in touble with the local sheriff if i have it too loud lol..chit i still 3 orial amps from the 90's im staring at in my office lol..hey remember alpha sonic amps lol..


what ever amp you decide to buy make sure its a class A,,that is where the power starts and look as the total harmonic distortion... point .05 is a good number if you see a .50 then the amp will distors the music faster then a .05 and 20~20000 hertz which is a snappy amp for dase and all across the board..

Mainly because I already have it. Is the amp too crappy to run the JL's? I dont want to ruin $600 worth of speakers by running a $100 amp but if it will work, then I'd like to use it..

As far as a sub amp, I'd like to spend as little as possible.. $250ish?

An Alpine PDX 1.600 will sound great, have low power draw and they are priced around $275 new on ebay.

the subs that I have say that they are "selectable 1 or 4 ohm".

I am so confused as to how much power I need to run these. Website says max is 1400w and constant is 350w each.

Im leaning towards this Rockford Fosgate Prime R1000.1

a 4 ohme speaker will take more power to run,,a 1 ohme will take less power but will also turn up faster and distort easier.. just make sure its a class a mosphet amp..in other words the amp will be more efficient at 4 ohmes then 2 ohmes..

I just installed a Kicker 450.2 & a 350.4 running 4 kicker 6" & 2 10" sub boxes in my wifes pontune boat and they rock the toons very nicely. My Eliminator has 2 700.5 & a450.2 pushing Rockford Fosgate (8)6.5" (4) 8" and (4) 10" subs. I expect it to delaminate the interior when cranked up!! All amps were bought on Ebay for under 300.00 each. Speakers were less than 1/2 retail also. Randy

MTX amps are a good reasonable choice. Highly under-rated at 12v and come with a birth certificate that shows true power and specs.
