Topic: Car amp for home subwoofer

[qguy]

Whats your thought on this

Cant seem to find a subwoofer plate amp...

I was thinking of getting this

and conneting it to 2 passive 12 inch subs

I too am having a hard time looking for a plate amp that suits my needs.  Maybe we can start a group buy? 

Anyway, back to topic.

I have considered using car amps too, but here are my concerns:
1.  That particular amp that you have on the link is not a good amp, and may not take the load of 2 subs. 
2.  If you intend to use a car amp for home subs, its best to look for one that is:
     2.1 a high-current design (can sustain a 2 ohm or greater load, and doubles its power when you increase the load)
     2.2 power efficient.... as in Class D mono, or Class T digital designs.
3.  Introducing an outboard step-down transformer may create a nasty hum at around 50/60Hz.
4.  Its better if the amp has a 0 to 180 phase adjustment
5.  Its better if the amp has an infinitely adjustable crossover (not just 3 positions like that amp)
6.  Its better if it has a high-level input

Thought about this too...
The amp on the link nga lang is one bootleg amp... Taiwan or China made V12....

I've got a mono class d amp (1ohm stable at 600WRMS) sa auto... parang na-tetempt nga akong ilagay sa bahay. One thing lang is that mahirap maghanap ng power supply na kakayanin yun, unless ang gawin mong power supply configuration is may naka-parallel na 12v battery kahit na 1sm lang (to regulate the voltage and supply the current the power supply cannot handle on some extended bass notes)...

Matrabaho lang din kasi eh, and wala akong paglalagyan nung box ng subwoofer ko... Mawawalan pa ako ng thump box sa sasakyan...

An additional cost: You'd need a 12V DC hi wattage converter that would set you back around 4K to 5K

Try ordering online:

Parts Express Subwoofer Plate Amps

[qguy]

cost of the amp and cost of shipping would be expensive, baka mas mura pa bumili ng DTX sub and get the plate amp na lang..hehehe

or use an integrated amp and connect an outbord subwoofer crossover....mukhang dito ako mapupunta...

mga sir try calling SPL Audio Marketing @ 735 54 40, they have a subwoofer power amp module that cost around 7k, power i think is 400wrms, these are the modules on professional active subwoofers

[adpm]

i have installed this kind of set up... ok naman ang tunog ng subwoofer... baka makatipid ka sa power supply .... use an at or atx powersupply ng pc... 250 to 500 watts iyan... kayang kaya...

does this come with a variable low pass? I feel like I can cut my sub lower, it's just that the cut off is fixed. I'll probably just diy another one if it does.

HI,

if you are looking for plate amps, you can get it touch with steve slater, he sells plate amps at a very reasonable price...

when using your car amp as subwoofer amp, you may as well build a conventional power supply for it...

... but really ... I think this person is correct ... power supply (like this one) is not an issue if you use car amp for a sub amp ... very cost effective!

Merry Christmas Sir Tony!

I likee the info above ... do you have experience buying from them ... how much overhead cost added to an item if delivered here in Manila?

i have ordered yet, will do after the holiday season though, shipping costs are dictated by weight more than anything, i have emailed him and he is willing to ship to the philippines..

the plate amps he sells are for 220volts, so if you buy from him, it will be a plug and play thing...

Sir, what payment types do they accept? Credit card payments?  PayPal? 

[ATJr.]

paypal is fine, but in my case, he agrees to western union as mode of payment..
