Supercharged DCs Posted July 22, 2011 Report Share Posted July 22, 2011 I'd go with the 1500bdcp above all the other amps mentioned here... Quote Bassless once again.

kam311 Posted July 22, 2011 Report Share Posted July 22, 2011 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? 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 Hifonics would be a step or two lower than the sundown and rf the we mentioned, but they do pretty close to rated, I'd get the 2100 if I were you. But for that price you could also look into a crescendo bc2000. I think it's a step up from the hifonics and it's about 349 shipped Quote so far...

Supercharged DCs Posted July 22, 2011 Report Share Posted July 22, 2011 You won't find a good H/O alternator for under $200. You don't need one either though. For 1500w the Big 3 and an upgraded battery under the hood will do just fine, and anyone who tells you differently is an idiot. Quote Bassless once again.

TRTC360 Posted July 22, 2011 Report Share Posted July 22, 2011 <a href="http://tinypic.com?ref=2r3c8xw" target="_blank"><img src="http://i52.tinypic.com/2r3c8xw.jpg" border="0" alt="Image and video hosting by TinyPic"></a> 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 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 crescendo 2k, DC 2k?

Get more 0awg wire, finish up the Big 3. I haven't had experience with Optima, I normally suggest XS Power batteries to anyone looking to upgrade. Also, remove that capacitor, it isn't helping your situation at all, and can possibly hinder it. Edited July 22, 2011 by Supercharged DCs Quote Bassless once again.
