[QUOTE="Jeffdachef, post: 8597160, member: 650438"] He's running a DSP, its active bud.... if you actually had more understanding of how pre-out voltages work, EQs affect pre-out voltage and the guy said he cut a lot of frequencies there for the pre-out voltage is A LOT less than you would expect. In an SQ tune, whatever you are used to in SPL logic/common assumptions like gain at half is "bad", you need to throw that out the window completely. Totally different world here filled with EQ cuts and steep crossover slopes. its the tune he did most likely, Sounds like he had to EQ down a lot of nasty frequencies which can make it seem like your setup is not loud because its not blaring and screwing up your ears with a peaky response. OR he didn't use the full output level of the dsp to compensate for the loss through EQ cuts. What you can do is Increase the output level of the dsp or raise the gain, if any of the speaker sounds stressed or audio fidelity breaks up, that just means your JL amp is not making anywhere enough power to power your setup. The zapco "Might" be okay for the tweeters. However I'd get something with at least 150 x 4 to 200 x 4 for the mids. Or a giant two channel that can put out 800 x 2 at 2 ohms for the mids. 130 x 4 for the tweeters would be better IMO as well. So if its not a gain issue, its a power issue and I would not go with tiny power upgrades at all when it comes to SQ and loudness. Mids and tweets need power to sound good and get loud. It doesnt matter what RMS the speaker is rated for... With proper high pass / lowpass or bandpass crossovers in place, they take A FK ton more than rated power. [/QUOTE]
