Need help with car audio, Subwoofer recommendations

[Deathdiesel]

Okay I really dunno what to do anymore guys. Ive gotten so many reccomendations its unreal. Some people are saying only go with a 500w amp for a 500w sub. Some say to go waaaay past it like 1200w or more depending on the ohms.

Have you considered a cheap kit to use temporarily?

Instead of blowing $500 on something you might not prefer.You could buy a cheap kit to learn with and use while you save for what you want in the future.

$139 for amp, enclosure, both subs and instillation kit.Plus its from PepBoys not Ebay.

At this point im kind of considering it. The only reason why I dislike that idea, is because of it would ruin my trunk space.

I think I may finally understand the whole wiring idea.

Please someone correct me if im wrong, but this should be correct as per what ive learned.

I should be safe, to use this amp:
Sony XplMdâ„¢ XM-ZZR3301 Mono subwoofer amplifier — 600 watts RMS at 2 ohms at Crutchfield.com OR AN AMP OF SIMILAR WATTAGE

with this subwoofer 500w dual 2 ohm:
WoofersEtc.com - SD-2 10D2 - Sundown Audio 10" Dual 2-Ohm Subwoofer
Wiring in parallel, making the total ohm 2 ohms to the amp.

Would this be correct? This would be making around 600watts to the sub, but guessing that they are overestimating, im gunna guess around 450watts actually going into the subwoofer. Would this be a safe load, and proper numbers and everything?

You would need a dual 4 ohm sub to wire to 2 ohm final load for that amp.

How does that make sense? 2 voice coils at 4 ohm =8 ohm if wired normally, and 4 ohm if wired in parallel right?

I saw kits from a few more reputable brands on amazon, MTX, Pyle etc for around $200.They had a few kits with a single sub if your still worried about trunk room.

All of that stuff is higher quality than what I originally posted

half right... wired in series they would be 8 ohms, but, wired in parallel 2 ohms...

The resistance doesn't stay the same when wired in parallel, it gets cut down lower. A dual 4 is two 4 ohm coils so you're talking about doubling that in series to 8, or halving it in parallel down to 2. If it was three subs you'd have 1/3 of the resistance as the final load, in parallel so 1.3333 ohms.

Okay now I get it, so I need this woofer then, with the same amp, running at 2ohms, correct?

WoofersEtc.com - SD-2 10D4 - Sundown Audio 10" Dual 4-Ohm Subwoofer

So correct me if I am wrong, but it would be safe to run this amp with 750watts @ 2ohms x1, just keeping the gain down, that way the amp isnt maxed out or hitting near its limit? http://www.crutchfield.com/p_109GTO751E/JBL-GTO-751EZ.html

Yes, that would work. As far as setting the gains, that will work.
