line output converter or amp quality?

[rklabon 10+ year member]

i have 2 12 inch type r's that don't pound like type r's at all..the problem is either i have a pyramid 2700 watt amp which i know is bad quality..or that im using a line output converter and the signal is no good..but i don't know why they dont bump like crazy...if it is the amp i am gonna get the Alpine MRD-M1005 V12 Digital Mono Amplifier

What voltage is the amp getting? Check your ground, and what size wiring do you have?

ditch the amp, check your wires.

That kinda box you running them in and whats the RMS on your Pyramid

the type r's are in a obcon vented box....is used 4 guage on everything..i got a 6 farad cap too..

all the connnections are good on it i think it just might be a bad amp...it doesn't even say the rms on it...just the big max ouput numbers...its also a 4 channnel amp bridged down to two subs

thats it...its not pounding my type r's like it should

 

[90accordman 5,000+ posts]

its probably putting out about 500w total

oh really.. thats no good..whys that?? would the alpine v12 1000 watts rms at 2 ohms be a lot better

Are your subs dual 2's? Wired in series for 4 ohms each??

Regardless - your amp's rms ratings are -

75x4 at 4 ohms stereo

115x4 at 2 ohms stereo

230x2 bridged.

With 2 20A fuses those power numbers sound reasonable, but for Type R's do do their thing, I'd say power's what you should be most concerned with, not the LOC.

okay...yea a friend from mobil link said the line out converter gives a more crystal signal then rca's from a head unit...but now i guess im not worried about it..just need to find an amp

ummm, he obviously doesnt know what hes talking about, quit talking to him and avoid his advice at all costs.

yea that didn't make sense to me that it could take a signal to speaker convert it to a rca signal and it would be more clear...Kenwood Excelon KAC-X812D thats the amp im looking at
