subs too close?

[kam311]

Those amps sell for a pretty penny! You could do that! But there are also amps that put out good power for less than the rf! You could sell both kickers and get a nice amp and still come out a little ahead maybe lol

Using pass thru is fine. Gain matching is tricky, you have to measure the output voltage of both amps and make sure they are the same AND make sure neither amp is clipping.

so i can use a DMM and a 33htz test tone to see what the voltages are at on the speaker terminals?

and the clipping is with an o-scope correct?

not an L shaped port...just a slot. aproxx 17 inches deep...15 inches tall x 3 inches wide

Then it's probably a gain issue because you're using two amps. One gain may be slightly higher than the other

i just dont get why one amp picks up the lows better...im using the older gray zx750...and a new 2010 zx750(black one)

could there be a diff between them in power and shit?

Yes. This is the problem. You set your gains wrong and the amps are different.

FML. i jus wanna sell em both. and get a RF t-1500.

run it at 1 ohm.

If you did this, you would not be disappointed

what would u reccomend for bout 1600 RMS at 1 ohm? that is cheaper then RF

[kam311]

Yeah man I'd say get a t-1500 or a nice amp that does from 1500-2000 watts. Makes life easier lol

i had a RF p.1000.1 but then i thought 2 zx750's would be louder...but i fucked myself over now...i just sold my p.1000.1 to my buddy.

i had em pushin around 1200rms from tht RF amp. but i was lookin for a wee bit more.

any suggestions on a good cheaper amp than a t-1500? but still gets me around a true 1500RMS

Pretty much any amp that does that power will he cheaper lol. Honestly I'd go with a sundown saz1500. Or I'd stick with the original rf idea

Basically, but check the voltage at the amp, no speakers hooked up. Also, once you set the voltages right, if you use an o-scope the check for clipping and you have to adjust the gains, gotta go back and match them again.

AQ has some nice amps, so does sundown, dc audio...lots of nice amps that are cheaper than the RF amps. None of them have cp though! But you won't be disappointed in an of what I listed.

looked into a DC 2k...shipped to me for 595....dont rlly wanna spend tht much.

i saw a used t1500 on Craigslist for 300. rlly thinkin about it. but idk. id like a warranty.

i was only looking to spend 300-ish.

whats your word on a hifonics BRZ1700.1 and BRZ2100.1

would the 1700 actually put out about that much true RMS

or should i go for the 2100?

those are decently cheaper. what do u think about the quality tho

[kam311]

The sundown is underrated by quite a bit, that's why I suggested it, because after box rise you'd probably still he seeing the most power. Rf is underrated as well, and like skippy said, it has cp which means that it makes 1500+ at 1ohm and makes nearly (if not exactly) the same power at 2ohms making box rise not an issue.
