Horns that could do midbass would be much too large to fit in a car.

Just picked up two 4x8 sheets of 19mm maple. $120 later

A subwoofer will not blow a hole in the surround unless it was "helped" along.

See project log link in my sig.

Overdrive pulley for the alternator will help.

I'm not lol More than enough power for the FRs, which I should be getting by the end of the week.

I did some of the frequency response of just the left channel of the DIY amp... output of the amp set to 2.83V & input of 0dB it is within +/-0.5dB from 50Hz to 25kHz, very slight roll off on the low end, down -1.5 @ 20Hz.

Hmm, how about a list of decent Ale's. Red Hook ESB Summit Pale Ale Goose Island Honkers Ale (cheap! and okay) Newcastle Nut Brown Bass Ale Sam Smiths Nut Brown Bells Amber Ale Had lots of Summit while I was there. Good enough. Next time I'm there, we have to spend more time at the micro breweries. Or perhaps my house. I can pick up some Growlers. That works too

Sundown SAE-1000D for the sub. Budget??

My front end came to a little more than that lol... but still not too bad, under $200.

you used to be an engineer major? had every intention of being chemical or mechanical but honestly one bad professor turned me away. That and i just didn't like the attitude of every single engineer that i met. most engineers are boring as hell and very socially inept So get an engineering degree and go into sales, no competition Truth be told.

T0p

mad cows attack! Serious.

I'm pretty much addicted to Guinness, weird.

I am not an engineer. Fine, physicist

delay top

Can't send Canadian beef

matte black, mmm Rear end is a little high though.

That looks like a roast and not a steak. Unfair since I dropped 6 bills on three of us for dinner at Carlos & Johnny's. Theres places where food costs that much!?!?!!!??!!!!! Holy crap, thats about half of what my truck is worth. Looks like a rib steak maybe... I dunno, not something I'd eat. T-bone & sirloin, thats it. Mind you, I've never bought a steak at a grocery store, all grain fed right from the farm. that must be nice. It is, you can definitely tell the difference. Now, I am going to remove a steak from the freezer so I can marinate it for 24 hours & eat it tomorrow for supper, mmm.

My OINK ratio is around 1.4 now.

My DIY amp power testing results are up: http://www.soundsolutionsaudio.com/forum/i...id=301173

Just completed the full power testing, so I figured I would share. Equipment Hewlett Packard 4935A Transmission Test Set Tektronix TDS 3032B Digital Oscilloscope Fluke 189 True RMS Multimeter Testing Procedure Test #1: This test will full power test each channel separately for comparison with the all channels test to follow. Connect a 4 ohm resistor load to the left channel output. Connect the transmission test set, which will be set with a 0dB 1kHz sine wave to the left channel. Measure RMS voltage across the load resistors at the point of clipping with both the oscilloscope & the RMS multimeter. Repeat for the right channel. Repeat with a 8 ohm load. Test #2: This test will full power test both channels simultaneously, also known as the all channels test. This test challenges the transformer & power supply to provide the necessary energy to power both channels at full output power. Connect a 4 ohm resistor load to the left & right channel outputs. Connect the transmission test set, which will be set with a 0dB 1kHz sine wave to both channels. Measure RMS voltage across the load resistors at the point of clipping with both the oscilloscope & the RMS multimeter. Repeat with a 8 ohm load. Testing Results All verified with the Fluke RMS multimeter. Test #1 Left Channel 17.6 Vrms into a 4 ohm load: 77.44 Wrms 19.2 Vrms into a 8 ohm load: 46.08 Wrms Right Channel 17.6 Vrms into a 4 ohm load: 77.44 Wrms 19.2 Vrms into a 8 ohm load: 46.08 Wrms Test #2 Left Channel 17 Vrms into a 4 ohm load: 72.25 Wrms *** Vrms into a 8 ohm load: *** Wrms Right Channel 17 Vrms into a 4 ohm load: 72.25 Wrms *** Vrms into a 8 ohm load: *** Wrms Conclusion The amplifier much preferred powering the 8 ohm resistive load, as the numbers show. Typically, an amplifier will double the power output when the load is halved. In this case, it did not. This could be associated to the transformer or power supply being undersized or the input voltage not being constant as I do not have a variac to keep the circuit from loading down. I am confident that the power supply was not able to supply the amplifier with the required output to properly drive the 4 ohm load, as the all channels test shows, the power output does not dip very much at all when the transformer and power supply is powering both channels at full output power & I know the input voltage would not be loaded down enough to limit power output like that. I was happy to see that the output of both channels match for all tests. I was unable to test the 8 ohm all channels power test due to not having enough high power resistors to make two 8 ohm loads. I will pick up more & complete the test at a later date. During the 4 ohm operation, all components stayed cool, but there was a slight ~1kHz oscillation that I could hear coming from the amplifier when the output got very close to clipping. This oscillation disappeared when the 8 ohm load was introduced. I would conclude that, while this amplifier can power a 4 ohm impedance perfectly fine, you will not gain anything by using it to drive this lower load. Please read this to find out why. Therefore, using this amplifier with an 8 ohm load vs. 4 ohm load will result in not only better performance, but a lower current draw, less internal component noise, cooler operation & a longer life.

SQ isn't RTA either. Completely flat frequency respone is very unpleasant. Only reason why this has gone this way is because the title says "this is SQ", but all I saw were batteries, a wall of amps, a wall of subs & a TL score. That is not SQ...
