Please help home audio/car audio mix problem!!!

by joshmw86 / May 24, 2015 8:36 AM PDT

I have a type r Swr-1242d and I'm not sure if my carver pm-1.5 power amp will need a pre amp to run the sub or if the amp itself is sufficient. My receiver is an old jvc A-X900 which is running my 2 Polk audio towers. Please help

Clarification Request

A preamp is before the amp so maybe you are talking about a more powerful amp. For me I rarely need the preamp since I moved away from turntables.

When matching speakers it's all about Ohms. Then Watts. It's fine to drive a speaker with less Watts. Usually you never have a true drive issue but let's hear why you think a preamplifier was called for.

Just found the PDF on that. 300 to 600W per channel.

You will need more help than me here. What you want to do can be done..but how, is the question. a good geeky friend would help. First problem I see is that there are NO sub-woofer output. Now a speaker can be hookup to a system without a SW output but I don't know enough to tell you how though, sorry. I think you need some sort of filtering network, which I know just enough to be dangerous, hehe. You see, I have one of those SW but have never look inside to see what's there.
