actully i have found the opposie to be true... when i bought a 1500 watt RF it came outta the box w/ the power certificate sayin it had been tested to put out 1,825 watts

yah same here see with RF they run lots of tests on the amps and give you a read out sheet of what they put out......both my amps were 100+ watts over the original rating....and if RF is a fad then why were they around for so long...heck even my dad had an RF amp in his car when he was 18...it was stolen too.... :?

aight, I worded that statement poorly. What I meant is that yes, RF amps are great amps, but for the price you can find better. Take for example an RF amp, say, 100 watts costs around
$200. You can easily find other amps of the same or similar quality, that also put out 100 watts for a lot less money. With RF it is a good brand, but you are mostly paying for the name. There'* plenty of other amps that will perform similarly for less money. (putting out the same amount of tested power, not what they're 'rated' at.)

Don't think I'm saying RF is bad, I'm not, there'* just other stuff for less money that works just as well.

What is the manual refering to with the capacitors and inductors?
Are these additional required pieces? I thought I would be able to connect the sub directly to the amp.................
Please Help!!

Both companies put out great products, the JBL 1200.1 is one of the best huge power amps around. Both are very underrated, and will take much abuse. I will agree RF seems to be more popular with people then JBL, they are in all stores pretty much. Either will work fine, just pick the one that works best with your Budget and setup. You might like the Fosgate bass ***** etc. You might have a full fosgate system etc. I might do that route, as i have a nice fosage deck now, and i'll either get infinity or fosgate components eventually. Maybe JBL if I hear a pair I like.

Yes, this amp does not come with a built-in crossover. You will need to buy additional crossovers for the full range speakers, and for the sub. If you do not do this, you will have midrange sounds coming out of the sub, which will sound wierd, and you will also have low frequencies going to your full range speakers, which may cause distortion, or even speaker damage. If I were you I would try to get an amp that already has a built in x-over, (unless your budget doesn't allow)which will make things easier. You can still get this amp (80.4) and it will work fine, but you should definitly get the x-overs.

My JBL GTS 180X (older) has a built in crossover, and then a way to hook up a custom one like mentioned above.

Thanks TiMSmo0th,

What is confusing me is that there are switches on the amp for "high-pass" and "low-pass" and dials on the amp. Are these just to fine tune before hitting the crossovers?

Also, my components came with crossover boxes (passive I am assuming) but no adjustments on them.

The high pass and low pass is the factory crossover!!!! The **** is for gain, etc. Did you get manual? If not check out their website. The other hookup is for a different crossover if you don't want to use the factory settings.

O so it DID come with a built in x-over...
well then, you can just use that instead of the capacitors. You should refer to the manual for help. Im sure you can download it off of the manufactures' site if it didn't come with one.
