  1. that amp can run both your subs, but getting a more powerful amp, would be ideal... i wouldnt run 2 sub amps. id just run 1 really powerful one and heres how to set your amp gain. the correct test tones (50hz for sub, 1khz for mids/highs) are at the very bottom https://jlaudio.zendesk.com/hc/en-us/articles/204374120-Amplifier-Level-Setting-Guide note.. set deck sub volume to 3/4. that link doesnt mention it, but JLs amp manuals do
  2. did you set your gain like JL recommends? .... deck 3/4 volume bass and treble = flat deck sub volume 3/4 crossovers off bass boost/loudness off 0 db 50hz tone for subs 0 db 1khz tone for mids/highs the correct test tones are at the bottom... https://jlaudio.zendesk.com/hc/en-us/articles/204374120-Amplifier-Level-Setting-Guide
  3. run a 12" sealed, i do. i listen to Metallica, Eminem, Bass Mekanik etc, sounds great, shakes my entire Accord sedan with ease. i have the 500 watt version of this amp, things solid https://www.woofersetc.com/c-23-subwoofers/c-34-12-subwoofers/p-9261-sa-12-d2-sundown-audio-12-600w-dual-2-ohm-sa-series-subwoofer.html https://www.woofersetc.com/c-3-amplifiers/c-27-one-channel/p-10270-r750-1d-rockford-fosgate-monoblock-750-watt-prime-series-class-d-amplifier.html my setup...
  4. audiofanaticz is right. i have an Alpine 9887, the RCA outs dont clip at full volume. but the internal amp clips at volume 21 out of 35 i have an oscilloscope, scoped it myself
  5. play a 1khz test tone. you can hear clipping. tones at the very bottom. you can wire up your speakers in series too if youre afraid you might burn em up https://jlaudio.zendesk.com/hc/en-us/articles/204374120-Amplifier-Level-Setting-Guide
  6. gotta set your gains right and use test tones. heres how. tones are at the very bottom https://jlaudio.zendesk.com/hc/en-us/articles/204374120-Amplifier-Level-Setting-Guide
  7. if your amp puts out more power than your speakers can handle, you dont have to worry about clipping if you know how to adjust your gains correctly if your amp puts out less power than your speakers can handle, just turn the amp up until it clips, then back it off a hair. you can hear clipping
  8. just reset your amp gain. heres how. the test tones are the WAV files at the very bottom of this page.. https://jlaudio.zendesk.com/hc/en-us/articles/204374120-Amplifier-Level-Setting-Guide
  9. how i set mine.... deck, just under clipping. bass/treble flat. sub volume on deck, maxed. xovers off. then i turn amp up until i hit target voltage, so long as its not clipping i use a 1k 0db tone for mids/highs. 40hz for sub

  11. a flat frequency response = better sq. ported boxes peak, thats why theyre louder than sealed boxes. if the peak is BIG, it will get real loud but wont sound very good id add a 2nd sub and run them sealed if you want to keep the sq you have but want it louder
  12. clipping will only ruin a speaker if its too much power for the speaker an amp that puts out 100 watts, at full clipping, is LIKE putting out 2x the power (200 watts) but if its hooked up to a 500 watt sub, it wont hurt the sub and if you understand that, youll understand how a 75 watt amp CAN cook a 100 watt speaker
  13. i bought this scope... http://www.elexp.com/tst_hhs5.htm works great and super easy to use
