  1. The best 350 dollar amp you will find is a Crunch GP3000-pro. They are strong as hell. I had one pushing two 18in Q's. If I needed 2k watts cheap I would buy one of them for the head room to grown and just watch the gain on it.

    I paid 500 for a new SAZ-1500 and then paid 350 shipped for the Crunch GP3000, If I had to do it over again I would buy the Crunch amp.

    He needs an amp for competition so it has to be rated below 1800w

  2. well i need more like 2400 at 2 ohms man. 600 rms per sub. 4 OA 15's

    i could handle 750 rms a sub but still i dont like to push my luck haha

    its safer to use a slightly more powerful amplifier since on a smaller amp you might turn the gain up too much since you would want to give your subs more power

  3. Why such a funky load after all is said and done?

    Funky load? A load doesn't have to be a whole number or 1, 2 or 4 ohm.. as with the case of most 4channels is that they put out the most power at 2 ohms per channel, so i wanted to get as close as possible

    This is how parallel impedance is worked out:

    1/Rtotal = 1/Rmid1 + 1/Rmid2 + 1/(Rtweet1 + Rtweet2)

    Rtotal = 1/ (1/8 + 1/8 + 1/(4+4) )= 2.66* ohm

    Ohh wow I feel dumb, well sounds like you should go for it tbh.

    You're not dumb, you just learnt something new :) I think i'm just going try it out, but i still have about a week before my mids arrive so we'll see then :S

  5. I dunno about the cap but why would you wire it into the speaker wire? Wouldn't it go inline with your amps power wire?

    Capacitors inline with tweeter are used as highpass filters, they cut off at a certain frequency according to their capacitance

  6. You have 2 component sets ... why don't you use the passive crossovers that came with them ... then series the complete sets to a 8 ohm load for the 2 channel amp ???

    or ... what final ohm load do you want the amp to see ??

    My idea was to have a 2.6ohm load(actually it should end up being a bit less) on each of the front 2 channels of my 4channel so that i'll get about 80 watts a side,

    that's the reason that i want the tweeters in series, i'm certain that the cap to will take the power and theoretically the circuit makes sense...

    but i just want some advice from some experienced people

    thank you for your reply :)

  7. Well i have 2 set of JBL tweeters that are 4 ohms each, and i have a bipolar crossover capacitor which handles quite a decent amount of power, can i wire both tweeters in series and then to one capacitor per pair?

    like:

    (+)---------------------(tweeter)-----------(tweeter)-----------(capacitor)-----------------(-)

  8. Most entry level, base model speakers are pitchy (bright), cause they have a fixed +/- for tweeter crossover. But you also need to take into account the staging and speaker placement.

    Proper angling and placement can make even the cheapest speaker sound good. So its not just the quality of the product, but also the quality of the install.

    Very true, his tweeters are very far forward on the dash, and its a big dash so they aren't right in your face, that's probably why they don't sound bright in his install, thanks for the informative reply :)
