HHR Ed Posted April 15, 2014 Report Share Posted April 15, 2014 Won't underpowering a sub cause your amp to heat up? No, why would it do that? The amp does not operate differently according to what a woofer's power rating is.

rockFord_Expedition Posted April 15, 2014 Report Share Posted April 15, 2014 Won't underpowering a sub cause your amp to heat up? Insufficient electrical and prolonged use especially at max volume will cause amps to heat up. None of that is because it makes less power than a sub can handle.

BZRK_J Posted April 15, 2014 Report Share Posted April 15, 2014 I had 2 Lanzar shallows on a Pyle "2000" watt 2 channel and it was constantly heating up cause I had the gain up too high to even get a little bump out of them. I just read I'm not the only one that thinks the same. Link to comment Share on other sites More sharing options...

I just read I'm not the only one that thinks the same. It ran hot because the gain was up too high. The gain was up too high because you adjusted gains improperly to try and overcompensate for lack of power. You tried to overcompensate for lack of power because you wanted it louder than what it really could do. You wanted it louder than what it really could do because you bought equipment not up to your standards. The amp did not heat up because the woofer was receiving power lower than it's rating.

cgrez33 Posted April 15, 2014 Report Share Posted April 15, 2014 Can you run a 2200w sub on a 2000w amp? Pretty sure this proves my noob status... they lied...or were wrong.My cousin has been doing this since 1993 so I feel safe going with the 4g on this project. Anyway not arguing on that just wanted to make sure I am not going to blow something up doing a 2k amp on a 2200w sub.Actually, that proves your noob status. Underpowering a sub is fine, but underpowering an amplifier is not. I have been doing this since 1992 so I trump your cousin. HA Anyway, a 2000W amp will consume almost 3000W from your electrical. Being that it is around 65-70% efficient. At full power, it will draw about 250A when voltage drops to 12V. Running wire from front battery to an amp in the rear would be about 16ft of wire in most cars. According to electrical law, Pure Copper wire, 4awg can carry about 90-100 Amps at that distance. -Pure copper 1/0 Awg can carry about 300-350A at that distance. Also, Most standard starting batteries can supply 40-70A at any length of time. 120-300A Bursts. Thats up to about 1000W continuous A good aftermarket battery about G34 to G31 size will supply 110-160A over time and 300-500 bursts. Thats about 2200W continuous Take good advice or dont. The cries of a low budget are all too common. If a person has almost no money, car audio is a luxury option, not a necessity. If you choose to play in that luxury, make sure you do it within your budget. A 2000W, dual battery system with 1/0 awg wire and a beefy sub may be what you really want, but if you can't afford it yet, start with a 1000W amp and expand over time. It's amazing how good a 1000W setup can actually perform. And the second hand market place is huge. Selling stuff when you want to upgrade should not be an issue.

Yeah I guess that's true. Ha. Had to have bump even if it was under 100 dollars. Link to comment Share on other sites More sharing options...
Foamyy Thee Squirrell Posted April 15, 2014 Author Report Share Posted April 15, 2014 I'm upgrading from a 1000w Rockford setup to a 2000w dc setup. Why I'm trying to sell my Rockford Punch 1000w amp. If the amps sells I have enough for a 1/0 wiring kit. Then I'll have the 2 batteries, a 2k amp, a XL sub, and a proper wiring kit. Within my budget, if I did my math right. Link to comment Share on other sites More sharing options...
